Easy XP
Search for a ranked match in Multiplayer mode. When it says "One player in game, waiting for more players", quit, and go to the main menu. Then, load a Marine mission on the Normal difficulty with a lot of enemies, such as the Praetorian boss in the "Research Lab" mission. Simply kill enemies now to get easy XP. Repeat this as many times as desired.







Audio Diary locations
Search the indicated locations to find all 67 hidden Audio Diaries:
Part 1/2






Part 2/2










Finding collectibles
While playing as an Alien or Predator, activate your Focus to get collectibles to appear as flashes on the HUD.
Avoiding instant kills as the Marine
In Multiplayer mode, keep your back against walls to prevent getting killed instantly by Aliens and Predators.
Getting past ventilation shaft as the Alien
In Level 3 as the Alien, the Queen will tell you to get to the bottom of a shaft with a huge fan at the top. When you get close to it, another Xenomorph will be blown into the fan. If you use your Focus, you can see two vents on the opposite wall. You can use either of them and safely jump to it despite the power of the fan. As you continue, you will find more vents to hide in. Use them to make your way down.
Easy "Ain't Got Time To Bleed" achievement
During the first wave in Survivor mode, kill all enemies except one alien. Let the alien get close and hit you once or twice, then run away while your health regenerates. When the alien gets close, face left or right, wait until you get hit with the claw, and then run away. If the alien tries the headbite, try to avoid it because it stuns you for a while. If you let the alien slash you once, it will take away approximately a half bar of health; thus, you will have to let the alien slash you 60 times to regenerate 30 bars of health to get the "Ain't Got Time To Bleed" achievement. It is quicker to let the alien slash you twice, but is not as safe as just letting it slash you once.
Easy "Spin Doctor" achievement
At the checkpoint in the "Ruins" mission where you must activate the three species symbols switches to open the exit, activate your stealth, and bring up your Battle Disc. There will be two soldiers standing by each other. Line up it so you can hit both soldiers with the Battle Disc. Hit both soldiers to get the "Spin Doctor" achievement. If you fail to get the achievement, reload the checkpoint, and try again.

Resident Evil 5 Cheats







Cheat: Unlocking Midnight Wesker Early In Versus Mode
When you have unlocked Battle Suit Jill and S.T.A.R.S. Wesker, you can select Midnight Wesker for play -- although he won't stay unlocked. When you are choosing your team, press RT to get to S.T.A.R.S. Wesker, then mash RT and LT at once and Midnight Wesker will be selectable.

Cheat: Inventory Duplication
This requires two very cooperative human players, and a Live connection (or a split screen game and two profiles).
1 - In the Inventory Lobby, invite a friend.
2 - Start the level (use 1.2 to make it easy). Have the host hand items (Rotten Eggs, First Aid, Ammo) off to the guest for duplication.
3 - With a full inventory, have the guest leave the game (it should say "All unsaved progress will be lost" -- select "Yes").
5 - After selecting "Yes," another question for the guest will appear asking whether or not to save status and ammo. Choose "Yes" to save and you will have all the passed-on inventory saved.
6 - Now, back to the host: Quit out of the game, but at the second question, choose "No" and do not save ammo and status.
7 - Restart the game with the two characters and you'll both have the ammo and items. Duplication successful! (Note: You cannot do this with weapons as you cannot hand them off to your partner.)
Addendum: A popular money-making strategy involves duplicating Gold or Rotten Eggs. These are worth $2,000 a pop, and 5 can be crammed in each inventory slot. That means you can eventually be duplicating $90,000 each time. Finding Rotten Eggs can be tough; they drop randomly from enemies in later levels. Also, for two people to increase the amount of eggs quickly, you'll have to pass them back and forth, alternating who is saving and who isn't. Finally, you may request eggs from the computer once the guest has quit out to make this process faster.

Mass Effect 2 Cheats


Cheat: Infinite YMIR Mechs
(Unconfirmed) When you reach the point in the Freedom's Progress mission where you are told to place your teammates around the giant blast door, you can trick the game into spawning extra YMIR Mechs (Ed: But why would you want to ... ?). First, position your team accordingly, and watch the cutscene. You'll now be confronted by a Giant YMIR Mech. Instead of killing it, turn around, and head BACK through the blast door. This will glitch the game back before the cutscene. Place your team around the blast door again, and the cutscene will play. This will spawn an extra YMIR Mech. Repeat as many times as you wish, but more than three YMIR Mechs will most likely kill you!
Elcor_Sculpture_Sux
Cheat: Max Out Skill Points ("Infinite" Skill Points)
To do this you'll need to have the Dominate skill, the Retrain Powers and Advanced Training upgrades and tons of Element Zero. You can get the Dominate Skill by recruiting Morinth (Samara's daughter), which means you have to sacrifice Samara in her own loyalty mission. A list of planets with Element Zero can be found below. First, purchase Advanced Training and choose Dominate. This will land you a bonus skill point, which you can use by instituting the Retrain Powers upgrade. Repeat this process for additional skill points -- one at a time!
Another technique by drenthez: This cheat works best when you have at least 10 available points. Simultaneously press X and A when choosing the fourth rank of an ability. This bumps up an ability to the next rank (fourth), but keeps any points spent to get there. For example: if you decide to do this when a rank is at level three, then it would cost 4 points which you would then be given back. When you do this using all 10 points on an ability, you get all of them back. Free Skill Points!
And finally, an addition by Dale Dearnley: If you do not press the X and A at the same time you can "Back" out and "Undo Talent Points". Go to the "Retrain Powers" menu. Retain and max out all powers using the above X and A cheat. Then go to the "Advanced Training" menu and buy a new power. It seems that a character can only have seven total powers at one time but you can buy the same power more than once so that a new one over rides an old one. Go back to the "Retrain Powers" menu and retrain all using the above X and A cheat, again. You will receive at least 50 extra Skill Points. If you up your skills in the "Squad" menu you will NOT get the extra Skill Points. This process can be repeated for more Skill Points.
IGN Guides
Cheat: Double Your Hacking Rewards
Occasionally, after completing a hacking minigame for credits etc. you can press A repeatedly as the window closes and cause the game to glitch out and let you hack a second time -- for another chunk of credits! We've confirmed that this is rare, but it does work -- so get in the habit of mashing.
