This is available at the beginning of the game. Simply weaken an enemy and then jump on its head to finish it off. Be aware that midgets may commit suicide and explode when close to death.

In the Dahl Headlands there is a race track left of where Skagzilla is. You must complete the track in under 31 seconds. Both the driver and the passenger can get this achievement at the same time.

-Thanks to Shadow9392 for the video.

These can drop randomly from enemies or can be given as quest rewards later in the story. Once looted, you can equip these from your backpack by selecting them and pressing to equip. You can also change which artifact you have equipped by going to your Skills Tab in the menu by pressing . To change, it move left from your Action Skill and press to change to which ever one you prefer.

This should come to you as you progress to the final level of your second playthrough. XP can be earned by killing enemies, completing quests, and completing challenges (Challenges can be found by pressing under the quests tab). Re-run the last area of the game on your second playthrough if needed.

Power-leveling can be used to get an early boost this and will definitely help as you progress through the game. To power level, it is required that you have at least 2 players, one who is just starting the game and the other who has completed at least Playthrough 1. The higher level character must teleport to the last level of the game in Playthrough 1 or 2 and rush through and kill all of the enemies. This will allow very large XP boosts to go to the lower-level player. It is possible to get to level 20 during one run and this is very helpful when starting out.

As soon as you have access to the first Catch-A-Ride in Fyrestone, you'll receive your first vehicle. Simply run over 25 enemies. Going at a decent speed should instantly kill an enemy. Progress can be tracked in the challenges menu.

Rakks are the bat-like creatures that fly in the air and swarm in groups of about 5. You should find swarms in different areas around the game or during the Rakk Hive fight when it shoots them out of its mouth. Simply shoot them as they swoop down and attack. On the quest "Get the Flock Outta Here" there is a hive near the windmills that you can get a lot to spawn.

Another method is to use the Siren class and use the phasewalk action-skill when they're within a close proximity. Because Rakks have fairly low health, they should die as you enter/exit phasewalk. -Thanks to KFZ Scrubs.

This should come naturally as you progress through the first playthrough. Simply collect and sell dropped loot as you complete the main storyline. If you do not have it by the end of the first playthrough, some weapons/class-mods during the second playthrough will sell for around $100,000+. This is cumulative, so you don't have to have it all at once. Progress can be tracked in the challenges menu.

This should also be achieved before the end of the first playthrough. Simply collect loot dropped from enemies, found in chests, and rewarded in quests and then sell it to a vendor. Selling med-kits and other loot will contribute to this achievement. Progress can be tracked in the challenges menu.

You can do this on splitscreen, system link, or over Xbox-Live. All you need to do is win an arena match. This is easy to boost with friends or by yourself on splitscreen. There is an arena in Fyrestone early on near one of the bandit camps. Only the host can start the arena once you have entered the lobby of the Arena. Nearby Arenas throughout the game will be marked by an "Arena" sign. The one in Fyrestone is near the starting area, and looks like a staircase that leads downward towards the entrance.

See Duelinator for more information.

You can do this on splitscreen, system link, or over Xbox-Live. Whether your teammate is overwhelmed by enemies and is downed or he purposely downs himself, run over to him and press and hold to begin reviving him. Once he is revived the achievement will pop-up.

You can do this on splitscreen, system link, or over Xbox-Live. As you progress through the game with a partner this will unlock.

You can do this on splitscreen, system link, or over Xbox-Live, as long as your partner has the achievement already. This is a viral achievement, so either search for an online game, or play with someone you know has it.

Weapon proficiency increases as either you or a partner kills enemies. You do not have to kill the enemy to gain proficiency. As long as it's equipped while a partner kills enemies it will continue to increase. This will come to you as you progress through the game. This can be viewed under the first tab in the character-menu.

You can do this on splitscreen, system link, or over Xbox-Live. To start a duel, go up to a person in your group and melee them to initiate the duel. For them to accept the duel, they will melee you back. To do this just let one person attack the other while the other person does nothing. Then do the same for the other person. You must not receive "damage" but damage on the shield will not negate this achievement.

Weapons and grenade mods in this game have different elemental types. You can tell what they are to the right of the stats on the gun. These can be bought in the store or looted from enemies and chests. Killing the enemies with the specific type of elemental weapon will count towards this achievement. You can check your progress on each elemental type in the challenges menu.

The rocket on your vehicle counts as an explosive weapon and will count towards this achievement. Adding elemental artifacts to your action skill will also count toward these achievements. -Thanks to KFZ Scrubs

This is unlocked fairly early in the game and can be done before you leave Fyrestone. One of the missions will require you to complete the objective and come back to Dr. Zed, he will then reward you with a class mod. Simply equip it as you would a grenade mod in the inventory.

You need to rescue claptraps in the various locations to be rewarded with 3 more inventory slots.

For a complete guide on the Clatptrap locations, look HERE. Thanks to Fizzmatix for the guide.

Once you reach level 5 with your Siren, you will unlock her action skill. Going in/out of phasewalk will send out a shockwave that will damage your enemies. Adding artifacts to this can also contribute to the elemental weapon kills achievements. To use the Siren's action skill, use . To exit immediately push in .

Once you reach level 5 with your Hunter, you will unlock his action skill. You can send his bloodwing to attack by pressing . After he attacks someone, he will return to you and you must wait the appropriate cooldown time before using him again. Spending points in the "Bloodwing" tree will reduce the cooldown and increase the damage and speed of Bloodwing. To be on the safe side, weaken your enemies before using the Bloodwing.

Once you reach level 5 with your Beserker, you will unlock his action skill. Simply press and go into Beserk. Use the for a upper-cut and the to jab enemies. Pressing the to kill enemies is faster because you can throw more punches than when using the .

Once you reach level 5 with your Soldier, you will unlock his action skill, which is a turret. Use to place the turret. Weakening enemies before you deploy it will be helpful.

This achievement will unlock once you have completed the first mission.

Note: This will generate a lot of brains but do not pick them up until you have spoken to TK. (see Braaaains for more info).

Story related and cannot be missed.

This achievement will take the longest to complete but can be done whilst completing other missions. Also if you have more than one player all players can collect towards the total this will make it far easier and quicker.

To activate this misson you have to take TK's wooden leg to his new "zombiefied self" His leg is located on a porch at the south west of the map in Hallows End once you have this in your possesion go into the buiding you found the leg on and give it to zombie TK.
He will then give you the missions to collect zombie brains to feed TK.

1. Collect 10 Brains
2. Collect 25 Brains
3. Collect 50 Brains
4. Collect 100 Brains
5. Collect 250 Brains

To get the zombies to drop a brain upon death try to kill them by a head shot. I found using a shotgun and aiming point blank in their face worked best, as opposed to using a sniper rifle.
After collecting each stage you have to return to TK who will eat the brains in front of you and then puke up a collectable as a reward.

Make sure that you collect the set amount for the mission. Return to TK then start the next mission. You cannot collect 200 brains and turn them all in at once.

Complete the quest "Prove Yourself." This is the first quest from the bounty board once entering the Underdome. Complete all 5 rounds in Hell-Burbia, The Angelic Ruins, and The Gully. Each arena should take roughly 25 - 40 minutes.

See "The Gully."

See "The Gully."

Complete the larger challenge for the specific arena. The larger challenge consists of 20 rounds that are split into 5 waves: Starter, Gun, Hoarde, Bad Ass, and a Boss round. Each arena should take roughly 3+ hours.

Complete Hell-Burbia, The Angelic Ruins, and The Gully using one character/account. Each challenge must be completed by the same character.

If you are playing with three friends everyone will be rewarded the achievement as just as long as they have been playing through all the same missions.

Awarded for completing the quest in T-Bone Junction entitled "Greasemonkey." You get this quest from Scooter as soon as you complete the DLC's second quest, "Boost the Monster." That quest requires you to find three parts for the new vehicle.

- The supercharger can be found in the lowest portion of the level closest to the far right semicircle as seen on the map. It's almost dead center of the map and behind a small shack.
- The nitrous oxide tank can be found in the middle of the right semicircle of the map in a trash pile Near Marcus' place. NOTE: Going near this part will begin the quest "Wanted: Dead!"
- The exhaust pipe can be found at the bottom of top left semicircle attached to a car that's crashed into a pole. It's right next to Zed's place.

With all three parts in hand, return to Scooter's and put the pieces on the Monster. After installing the parts, hit the switch and watch the scene. Once the Monster disappears, turn the quest into Scooter for the achievement.

After you complete the quest "Prison Break: Over the Wall" you will enter Lockdown Palace and receive the quest "Prison Break: Try Not to Get Shanked." Your goal here is to Kill Mr. Shank, grab the PTD and free Athena. First you must make your way through the prison until you see the shower scene and begin fighting Mr. Shank. The key to fighting him is to stay far away (he's a melee fighter) and take his shield down with an electric elemental weapon. Once his shield's down, you can shoot him with a fire weapon and he'll be dead in no time. After he falls, pick up the PTD next to his body and fight your way to Athena's cell. The achievement unlocks the moment you hand the PTD over to Athena.

After you complete the quest "Bridge the Gap" you will enter Road's End and receive the quest "Armory Assault." Your goal here is to kill General Knoxx, enter the code to the Armory (Blue, Yellow, Cyan, Orange) and blow up the Armory. The only difficult part of this for some may be killing General Knoxx. The easiest way to defeat him is to use a highly corrosive weapon on him. Also, be sure to kill any medics that appear right away. They love to drop their healing turrets which heal Knoxx very quickly. After Knoxx is dead, the rest of the mission is self explanatory.

GLITCH WARNING: In order to avoid your game glitching and making the Armory permanently closed, you must do the following:
- Do not quit out of the game once you enter the elevator shaft. Wait until the Armory explodes and the credits are done to quit out.
- Don't have the quests "Super Marcus Sweep" or "It's Like Christmas" in your quest log.

This is probably the hardest achievement in the DLC to do solo since he is level 64 on both playthroughs. Crawmerax is a giant lobster type monster that you fight during the quest "You. Will. Die." The hardest part about him is that both he and the little minions he has running around him can take almost all your health in just one hit. This means that you need to use a lot of teamwork with your partners to ensure that no one is concentrated on by the enemy. The way to actually injure Crawmerax is to shoot the purple soft spots on his body. He has six in total - one in his eye, one on each of his four claws and one on his back. Once the final purple spot is destroyed, Crawmerax will fall and drop a LOT of loot (very rarely pearlescents though).

In addition to the above, there are a couple of other little tips that may help you defeat this giant lobster.
- For his minions that annoy the heck out of you, the Green Craw Worms are weak against fire, the Armored Craw Worms are weak against corrosive, and Craw Maggots are weak against shock.
- There is a spot you can get Crawmerax stuck in that can really help you kill him fast. Read HERE for more info. Thanks to Powerman1469 for the help.

Loot midgets are fairly tough little buggers that jump out of various loot containers. They come in five varieties and can sometimes be found in multiple locations. Below is a list of the types of loot midgets and at least one of their locations:

Meat Popsicle: Hides in refrigerators. Can be found in the lowest portion of T-Bone Junction or in the midget village in Sunken Sea

Dumpster Diver: Found in the dumpster in the area where you kill Motorhead

Truxican Wrestler: Found in one of the lockers at the beginning of Lockdown Palace

Mini Steve: Found inside normal red weapons chests. Can be found in one in Lockdown Palace

Crimson Shorty: Found in one of the Crimson Lance Chests at the end of the Road's End map (just before the Armory)

Racers are the vehicle you drive around from the original game. They are the weakest of the three vehicles you can choose from. Lancers are the APCs that the Crimson Lance drive around. They essentially look like a tank with wheels. The racers become available for you to drive after you talk with Moxxi for the first time.

Once you are able to drive a racer, head on up to "The Ridgeway." If you haven't already, grab a racer and head down the ramp. At the bottom there should be a Lancer. The easiest way to kill it is to stay as far away as you can and shoot rockets at it. If you are being shot at, simply swerve back and forth. The weapon on the Lancer is direct fire, so if you move around they can't hit you. Once the Lancer is destroyed, the achievement will pop.

This achievement should come fairly early on into the DLC. You should be on playthrough two at this point and I suggest that you play the DLC on it to maximize the amount of experience you can gain. If you're like me, you may not have finished playthrough two of the original game. If this is true, I suggest you do those quests to get yourself to about level 52/53 before you even start the DLC. The reason for this is that playthrough two quests for this DLC start at level 51. If you're under that, you may have a tough time surviving.

See Ding! Overleveled to 11 for more info.

This is the highest you can get your level to legitimately. Getting there will require you to accumulate 5985083 total experience. Though this may sound like a lot, there's more than enough experience available in this DLC to make it there. Any experience earned from the original game or other DLCs count towards you experience total. Therefore if you haven't completed missions from those stories feel free to do so once download this DLC. With completing missions and killing enemies, you should level up very quickly. If you want to really expedite the process though, you could try to join a group killing Crawmerax as that boss and his minions give boat loads of XP.

Below is a list of all missions available in this DLC. They are separated by area you receive them with the quest giver in parentheses. You must complete all of these missions in the same playthrough in order to get the achievement. In other words, playing all but one mission in playthrough 2 and the other in playthrough 1 will not net you the achievement.

There are six statues to find and they are spread around the new area. Here are all the locations:

1. Hyperion Dump - When you first enter this location after you have collected the clap-components for Tannis, it will be directly in front of you underneath, a speaker.

2. Sanders Gorge - When you first enter this location you will see the statue in front of you, just past a few vending machines.

3. Dividing Faults - When you first enter this location, you will see the statue in front of you.

4. Scorched Snake Canyon - When you first enter this location, make an immediate left down a small set of stairs and another immediate left and it should be right in front of you.

5. Tartarus Station - In the winding path towards Wayward Path.

6. Wayward Pass - After defeating the Knoxx-trap for the second time, the statue will be located just outside his back door on the left.

This is the final boss in the DLC. After the cutscene, there will be a huge claptrap that drops down, the MINAC. There are sentry guns around the body. Take those out. Its weak point is the giant red eye on the front of it. Shoot that to defeat it. After it is defeated, the INAC will appear, kill the INAC and you will get the achievement when the credits start to roll.

This is similar to Brains from the Zombie Island of Dr. Ned. You aren't required to collect as many brains though. This is very similar in the way that if you have the required amount for the quest, any more you pick up will be voided out. You have to collect components from Clap-Traps that you kill. These consist of: Wires, Motherboards and Gears. These don't drop all the time, but they will drop frequently enough. There are four parts to the quest. Here is the amount required per quest.

1: 42 components
2: 75 components
3: 100 components
4: 150 components

Oil Cans are randomly dropped from Clap-Traps that you kill. There's a lot of grinding involved, so here's what Mad Ibrowz suggests:

"Go fight the Minac and when he appears, just hide behind the rocks near the van...

Where the van is, behind it you'll find a save point and a shed. Whilst standing in the shed facing out, turn immediately right and you'll see a silver crate with weapons in it. Next to this there's 2 rocks with a thin passage in between them. Simply just hide here... When the Minac comes near you and starts to shoot at you, however, he'll only be able to reach you with 1 turret. All you have to do is shoot the turret and once it's gone, you can sit where you are forever without being hit - he won't shoot you, his robots won't, you're safe. At this point, leave the game running (use a wireless controller) and when you come back a few hours later, there'll be a ton of parts all over the place because the Minac accidentally runs over most Claptraps. Simply run out, collect what you can or need and then if you don't have everything, just repeat the process once again."

This is the same concept as The Lubricator.

This is the same concept as The Lubricator.

This achievement requires you to collect 3 pink panties, 5 clap-fish, and 15 pizzas. These items are also dropped randomly from clap-traps.

This is the same concept as The Lubricator.
