Completing the game on casual shouldn't be to difficult for most players. Most players should do at least one run through on casual to get a feel for the game and to learn the levels.

As most hard difficulties prove a challenge for some players this might be quite a challenge for some and not so for others. Just take your time and play through the game on casual to get a feel for all the controls and how everything works. Each ghost will need to be approached with in a different method and each creature you run into will need to be tackled with caution.

These achievements do stack so if you want to do your first run through on pro and unlock most of the achievements you can.

Here are a few things to keep in mind while playiing on hard:

• Vent your pack on a regular basis
• Revive all team mates as soon as you can
• Know the area your heading into
• keep your distance, if you can
• Take your time

Required Upgrade: Slam Trap, all upgrades are accessible from the pause menu.

Use the proton pack to wear down the ghosts resistence which is display around your cursor, when it enters the red you will see a slam bar at the bottom of the screen. Drop a trap on the floor and hit while directing the ghost with the towards the trap. This may take a few goes but once you get it the first time it's pretty easy. You will also need the slam dunk trap which you can buy as an upgrade. To upgrade the trap press and scroll down the list until you find the slam trap.

Before you can do this you will need the Slime Tether add on for your Proton Pack. You will be given this as you progress through the game.

You will need to knock the ghost out before you can use the slime tether on it. Wear down it's resistance level and use the slam by pressing to knock the ghost out. Once knocked out change over to the slime tether by pressing and firing one at of the tether at the ghost and the other end at the trap.

Before you can do this you will need the Stasis Stream add on for your Proton Pack. You will be given this as you progress through the game.

This is a little harder to pull off more than the other traps, you need to wear a ghost out and make sure to knock him out, once knocked out hit to change to the Statis stream, freeze the ghost using the and drop a trap under the ghost by pressing .

You will get this within the tutorial, just drop a trap when indicated by pressing and draw the ghost to the trap.

Creatures are anything that aren't human, and show up as a ghost. Book monsters, golems, killer chandeliers etc. The first one you encounter will be in the kitchen of the Sedgewick hotel.

This is a lot easier than it sounds but if your not really paying attention you could miss this achievement. You should break enough stuff without having to worry about this achievement but if you want to make sure you get it once you get to the museum you can play through the "American History" checkpoint a few times. This exhibit will earn you at least $1 million worth of damage on each run. You must make it to the next room so the game saves your data at the checkpoint save, Repeat this as needed.

This will unlock once the game has been completed.

Before you attempt this achievement you must be prepared to start over, a simple mistake such as shooting a car can compromise this achievement. Let your team do most of the work and hold back in a corner, make sure you check your stats all the time to see if your under the required amount. This isn't impossible but it requires patience, The two levels to avoid causing any damage on are "Times Square" and "The Museum of History".

If you do make a mistake quickly quit out of the game and resume, check your stats and hope that whatever you just damaged didn't get recorded.

This will unlock once the game has been completed.

See "Spores, Molds, and Fungus"

Using your PKE scanner by pressing you will be prompted when an artifact will be close by. Artifacts have a purple glow to them while using the PKE meter so they quite distinctive.

There are 42 artifacts in total, you can find a full guide located here.

Creatures are either objects or things, you can tell a ghost apart from a create as all ghosts look human. There are plenty of them in the game just decide which one you want to scan. The first creature you run into is the fish ghost in the kitchen of the Sedgewick Hotel.

The best way to do this without any hassle is to scan everything paranormal that you come across. When you want to scan a paranormal being equip the scanner by hitting and aim towards it then hit .

There are a sum total of 53 paranormal ghosts and creatures in the game. Scan every single one you come across, if you find you have missed a few you can replay from a previous checkpoint and use this guide to help discover the ones you missed.

Load up any chapter on professional and keep reviving your teammates by pressing next to them. Do this 20 times and the achievement will unlock.

This will probably be easier for most people while trying to capture slimer, if you miss it then just allow any ghost to fly into you or attack you and you will become slimed.

You can either do this by crossing beams with your teammates or by firing a boson dart while close to a wall. Both methods will knock you to the ground.

While doing the tutorial mission at the very start of the game you have to follow the guys. Follow them down the pole by pressing in front of the pole to interact with it.

Use the Slime Tethers alternative fire to attach a ghost to any object in the room. Repeat this 15 times to earn your reward. You can repeat this multiple times with the same ghost to unlock this achievement.

While you are attacking a ghost drop a trap on the floor by pressing , wear down the ghosts resistance level and then trap it using your trap. Repeat this 19 more times.

When you first encounter slimer in the dining room of the sedgewick you will notice a ham just to the left of him. Run up to the table and fire at the ham by pressing , keep shooting at the ham until it explodes.

While luring Stay Puft around times square you will enter a building. As you make your way to the top you have to go through a large room where you will need to fight a small horde of marshmallow minions.

Kill all the creatures and then carry on trashing the whole office, smash anything and everything in sight that will break, this includes windows, pillars, desks etc. If you see the damage counter keep going until it stops counting. Open the door to carry on, you will have to fight more minions, use Boston Darts and trash whatever is in the doorway.

You come across a childs reading room as you make your way through the libary. It's quite obvious but if your not sure you will see a panda bear floating into a door which then shuts.

You have to enter through a door behind you, as soon as you enter press to use the PKE scanner. In the middle of the bookshelf's and in the middle of the room you will find a hop scotch games drawn on the floor. Leading away from the hop scotch you will find footprints leading to a tree with a dancing bear. Follow the hands prints around the wall which are behind the tree, this will lead you almost back to where you started.

Scan all the things you see in this video, hop scotch, handprints, bear. Once you do that the achievement will unlock.

As your progress through the museum you will enter the cival war exhibit, it's fairly obvious as there are 2 statues of soldiers riding horses in the middle of the room.

There are 4 speakers, one on the right as you enter, one to the left around the corner and 2 by each horse statue.

Once you return to Sedgewick you need to turn the power to the building back on, carry on progressing until the power is back on. Return to the entrance and you will find a door on the right side of the entrance. Enter the room and equip the slime gun, clean all the black slime off the walls and celling.

You will come to the maze fairly soon after you arrive on the island, once you find the hedge use the proton beam to set fire to to all the bushes around the maze.

While in the grave yard you will come to a big tree in the middle of a circle, you will need to fight a ghost a few minions. You can load the checkpoint "Airstrike" to get here. You will see a firely trail in the sky, shoot at these until you break the coffins. This may take a few goes to get but it's not that hard to shoot down the coffins.

There are water fountains located all through the game. You must use every water fountain in the game. You can load back to previous checkpoitns and collect each fountain, you must progress onto the next checkpoint once you use the fountain so the game saves your progress.

If the achievement doesn't unlock while collecting the last fountain complete the game or finish the last boss fight and it will unlock.

To see pictures of all the water fountain locations, check out the achievement guide for Ghostbusters HERE.

You need to beat every level of each campaign being the highest earner and coming in first. You can't fail any round you must complete each round with a victory.

If this doesn't unlock you must complete each campaign, there are 4 campaigns in multiplayer with 3 random game types each.

Join any game you feel comfortable with and capture 50 ghosts. Slime dunk will get you this achievement the fastest as you will capture between 15 - 30 ghosts a game depending on your skill.

Most wanted ghosts show up randomly while your playing through campaigns. So far I have only seen them in ranked play, once one shows up just ignore everything else and fire at the most wanted ghost instead. As soon as it's destroyed you will be awarded with a mark on your most wanted card.

See "No Job Too big" for further information.

When you join a ranked campaign you will earn money for captures, basically earn more than anyone else by captuing the most ghosts and killing the most creatures. Once you finish the level your on you can see how much money you have earned so far on the round end status screen.

Earn more than anyone else in the whole campaign even if it's just by $1 and the achievement will unlock. You must complete the levels fully otherwise it classes as a fail and the achievement won't unlock.

*Currently Glitched*

All 20 most wanted ghosts show up randomly in different levels, you can check your list of most wanted ghosts from the xbox live stats menu, the menu will tell you where to find the ghosts and what you need to do to provoke them to show up.

Not all the ghosts show up where they are meant to so if your playing with other people and a graveyard orientated ghosts shows up at times square don't be surprised. You can only collect these ghosts in ranked games, if one shows up concentrate on taking that ghost out.

Anyone can capture or destroy the ghost so it doesn't matter if you do or a friend does, just make sure you capture it as it may not show up again for a little while.

It is better to do this in Instant matches, it will be easier to keep track of what you have done. This achievement has a tendency to unlock early for some. You will need to complete around 60 or games with victory for this achievement.
