For these three achievements, simply complete all three acts (five levels each) of the Villain campaign.

For this you need to play an entire level in local co-op. Make sure to have the second controller turned on before you enter a level, such as in the Batcave or the Asylum.

There are 10 pieces in each level for a total of 300 through the Hero and Villain levels.

After completing the story mode on the Villain side you will be able to purchase everyone except the character Hush. To unlock Hush you will have to find and save all 25 hostages. Then you can purchase Hush as well to unlock the achievement.

Note: You can use codes to unlock all the other characters, but Hush must be unlocked by saving hostages.

You will need to purchase Nightwing and Batgirl for this achievement, both of which are available after the first Hero mission.

There are 22 vehicles total. This will cost around 500,000 to unlock everything. You will be able to buy them all after completing the Hero and Villain story modes.

This is easiest done on either the first Hero mission or the first Villain mission. Simply take your time and collect any hearts that drop to keep your health up.

As the description states, you can not have any extras enabled when trying for this achievement.

You will get this on the level "Breaking Blocks" (Villains, Episode 1, Level 5) through story progression.

For this you will need to do the following:

• Finish all story modes.
• Find all 300 collectibles.
• Find all 25 hostages.
• Find all 30 red bricks.
• Purchase all characters/vehicles.
• Purchase all suit upgrades/extras.
• Purchase all tidbits in the Data section.

If you have 100% and the achievement does not unlock, replay a mission and it should pop after the mission is over.

In the Villain level "Lure of the Night" (Episode 3, Chapter 4) you will build a giant clown robot. Once you've built that, continue down the street and some cop cars will show up. Walk over each of them to destroy them.

Note: If playing co-op, make sure you are in the driver's seat of the robot and not the gun-turret seat on its head or you won't get the achievement.

As there are 30 levels, 5 will not have a hostage to save. For a complete list to find them all, go here.

To see if you have saved a hostage, go to the mission selection computer for any episode and hover over a number. There will be a happy or sad face next to the circle if you have or have not saved the hostage in that mission. If there is no face, that is a mission without a hostage.

You have a bar at the top of your screen which will fill when studs are collected. Just fill it up completely on every level, on both the Villain and Hero sides and you will get this.

Tip: Use the cheats to unlock all the stud multipliers (see "Richest Man in Gotham") and use them from the beginning. You will get it after destroying just a few objects.

You will get this well before the end of the Hero campaign through normal story progression.

The suits are unlocked again through normal story progression. You will unlock all of them before the end of the Hero side of the game.

There are 15 suit upgrades, one for each red brick you can find on the Hero side. Find all the bricks, then purchase all the upgrades for the achievement.

Note: You can also just use the unlock codes for all 15 to get the achievement and bypass the need to collect the brick in the levels.

You will need four billion (4,000,000,000) studs to max out the counter. Since cheats do not disable achievements, I would suggest using the multiplier cheats and using them the entire time you play the game (story mode and free play) to make this go quickly.

• 4x - CX9MAT
• 6x - MLVNF2
• 8x - WCCDB9
• 10x - 18HW07

You should get this after finishing the final Hero mission, just make sure that during your boss fights, you make the killing blow on each of these chracters while controlling Batman. If you kill them while controlling Robin, the achievement will not unlock. Replay the necessary story missions in Story Mode if you messed up.

• Joker: To the Top of the Tower (Episode 3, Chapter 5)
• Two-Face: The Face-Off (Episode 1, Chapter 5)
• Riddler: The Face-Off (Episode 1, Chapter 5)
• Catwoman: There She Goes Again (Episode 2, Chapter 1)

Just enter a level as Two-Face and switch the second player to a goon, then kill him 10 times. Now switch the second player to a cop and kill him 10 times. Must all be done in one level, can be Free Play though (obviously).

You can do this at any time. Enter a level where you play as Catwoman, then take control of the other character and break Catwoman 9 times. Can be done in Free Play or Story Mode.

There are plenty of chances to get this, but the first (and maybe the easiest) is when you get attacked in front of the bank in "The Face-Off" (Episode 1, Chapter 5) of the Hero campaign. Just wail away with the  button. Use the Invincibility cheat so you don't get killed.

When playing as a character with superstrength (Bane, Clayface, Killer Croc, Man-Bat), press  and then  again to throw an enemy. This must be done 50 times on Policemen.

Go into Free Play (any level) and select Bane, then pick up Batman with  and hit  again and you will get this achievement.

Just walk up to a enemy and hit  as the Joker and you should shock the enemy. Repeat 29 times and you will get this achievement

You will unlock this after completing the level "In the Dark Night" (Episode 3, Chapter 4) of the Hero campaign.

The easiest way to get this is to go into Free Play with Gordon and Harley. Take control of Harley and hit  near Gordon to break him in one shot.

This can also be done during story mode during the Gordon fight. When he has one heart left, use Harley to kill him with the  button.

Once you unlock the Joker, enter Free Play mode and make both characters the Joker. Walk up to the doppelganger Joker and hit  to shock him for the achievement.

Hold down on the left thumbstick and hit  to do a backflips. Just keep tapping the  button to keep flipping for a total of 20 in a row. You can just back yourself up to a wall or line up down a long path, either way.

Like Wayne Manor you will need one million studs to finish this. But, unlike Wayne Manor, there are way more than one million studs total. No real need for a guide, just run around smashing everything in sight and you will get it in no time.

You will need to get Super Villain on all 15 Villain missions to unlock this room.

In the Hero level "The Face-Off" (Episode 1, Chapter 5) you will need to build a lever and ride some scaffolding up to enter a vent. Instead of entering the vent, make sure you have the Glide Suit on and jump off the scaffolding. This is more than enough time for the achievement. Just make sure to keep holding  to glide.

In the same place as the "Shot to the Goon" achievement, jump in one of the cars nearby and run into the crows of enemies instead of fighting them normally.

There are 21 total streetlights in this level, most near the beginning. The achievement is slightly glitchy though, so if you don't get it right away, start a new game and try again.

You will get this through story progression in the level "A Daring Rescue" (Episode 2, Chapter 4) of the Villain campaign.

At the very beginning in the level "A Poisonous Appointment" (Episode 1, Chapter 4) of the Hero campaign, you can build a carrot patch. Place a bomb in the middle and get out of the way and hold  and detonate the bomb and you should get this.

Can also be done during the Clayface fight in "You can Bank on Batman" (Episode 1, Chapter 1) of the Hero campaign by blowing up all the silver bars on the left side of the vault.

You can get this on the level "Little Fun at the Big Top" (Episode 3, Chapter 2) of the Hero campaign. When you get to the part where you see some stores you can go in there are about 10 flags. Target all of them so the yellow box is around all 10 and you should destroy them all and unlock the achievement.

Can also be done in either of the sections mentioned for "Destroyer of Worlds."

The easiest way for this is in the Arkham Asylum bonus level. Head to the second area to get the Venus ride on and kill 15 enemies, or just eat your partner 15 times.

All you have to do for this is hold down the  button while controlling Mr. Freeze to freeze an enemy. Repeat until unlocked.

While controlling Penguin, hit  and a little LEGO penguin should come out. You will need to use these to kill 20 policemen for the achievement.

While controlling Scarecrow, simply hold  to scare en enemy. Repeat until unlocked.

The Villain level "On the Rocks" (Episode 1, Chapter 2) you will need to mind control a cop to pull a lever for you. Instead, walk him off the edge and repeat until unlocked.

While controlling Batman, grab a goon with  and hit  again to slam them into the ground. Repeat until unlocked.
