Borderlands 2

Game Cheats:
Extra Wubs

True Vault Hunter mode
Successfully complete Story mode under the Normal difficulty setting.

Borderlands skin
Have a saved game file from Borderlands to unlock characters skin from the original game.

Item Duping
Place the desired item(s) on a character, and ready or create a second character to take on as many of the item as you wish. Start a two-player co-op game with the first character as player 1 (and the other character as player 2, obviously). Give desired item(s) to player 2 and have player 2 save and leave game. Quit game from PS3 system menu. Because the game doesn't save player 1 when player 2 leaves, nor when you quit from the system menu, now both players have said item(s). Repeat as desired (for faster duplication, transfer all copies of the item to player one, save-and-quit with both, and start over with the duplicates on player 1).

Badass Rank Farming
To build a high Badass Rank, and gain all the perks associated with it, create a pair of new characters in co-op mode and have player 1 beat player 2 in 50 duels. This gives 166 Badass Ranks. Save and quit, then start another new game, creating another new character for player 1 (don't bother messing with player 2's character). Fight another 50 duels, with player 1 winning them all for 166 more Badass Ranks. Repeat as desired, and delete the pile of unwanted characters when you're done.. If you set the controller configuration to something where you can just keep tapping the melee-attack button without ruining your aim at the other player, you can finish a duel-run like this in roughly 10 minutes. Thus, over the course of one hour, you can build up 996 Badass Ranks.
Easy Badass ranks
Create a new character and join the game as a guest on controller two. Stand in front of the guest character with your main character and start a duel. Win the duel and repeat the process. Fifty duel victories will result in a gain of 166 Badass ranks. Create a new character and repeat the process as many times as desired.

Easy money and Eridium
At the beginning of the Southpaw Steam & Power Facility, where you do the "Assassinate The Assassins" mission, is a room of lockers and small boxes. Check all the boxes and lockers, then go to the "Pause" menu. Select "Quit", then "Save And Quit". When the game returns to the title screen, continue your game. You will appear at the begging of Southpaw, and the boxes and lockers will have respawned with new items (weapons, money, ammo, shields, and Eridium). Loot the boxes and lockers again and repeat. The entire process is very fast and you can receive at least one Eridium every four times that the room is cleared. This is a good way to get black market items early in the game.

Minecraft reference
Go to Sanctuary Hole after Chapter 9. Jump off a cliff then go to Caustic Caverns. Run northwest to Guardian Ruins then go to the minecarts and turn right. Jump over the rectangular rocks then turn left to find Minecraft dirt. Break though it to reach Minecraft stone, cobblestone, and coal. Break though those to find Creepers, as well as blocks of gold, diamond, iridium and more. Kill the Badass Creeper to unlock Minecraft-themed skins (Steve Head, Steve's Clothes etc.).
