Infinite Eridium
Enter the Three Horns Valley, head northwest to the Bloodshot hideout and kill the Bad Maw boss. As soon as you take out Bad Maw, collect the Eridium, which he leaves behind. Once you enter the Bloodshot Stronghold head to the main menu and select 'Save and Quit'. Continue the game, go back to Three Horns Valley, deal with Bad Maw once more and grab additional Eridium. You can do this as often as you wish.

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

True Vault Hunter Mode
Complete Normal difficulty story mode.

Minecraft Enemies and Outfit
In the Caustic Caverns underneath Sanctuary, near the furthest edge, there is a shallow incline. If you go along the left-most cliff beside the incline, you will find Minecraft blocks. Breaking them will lead into an area with creepers from the Minecraft games, a golden ore block with a normal outfit, and a special outfit for defeating the creepers.

Duplicate Items
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.

Easily Reach Level 20
When you have a character reach Tiny Tina do all of her side missions until you make it to the final stage of her tea party. Here she wants you to lure Flesh-Stick to her little cove to join her tea party. Since you can fail this mission by killing him you can actually repeat that over n over for experience. On top of that if a second controller is available and you wish to make another character but don't want to level them up the normal way you can have that created person join your session and have them run all the way to Tiny Tina. If you keep them in front of her and your main character in front of where Flesh-Stick walks out you can kill him and re-accept the mission as fast as your trigger finger allows making anyone reach roughly 20-21 in a matter of minutes.

Easy XP Leveling
After completing the quest, "A Dam Fine Rescue", you will find Sir Hammerlock inside Sanctuary offers a quest called, "Mighty Morphin'" that involves taking an Injector and injecting Varkid Cocoons with a special serum. Injecting the serum into a cocoon forces a large flying Badass version of a Varkid. Killing one yields 1,900 Experience. As long as you don't complete or turn-in the quest, you can wipe the entire zone of cocoons, save the game, reload, and do it again!

Easy XP
At the end of Tiny Tina's Tea Party side quest you're required to lure a psycho named "Flesh Stick" back to her home. If you shoot and kill Flesh Stick rather than luring him back you'll reap a huge XP boost (750xp/kill on level 18 and around 1,800xp on level 17) which can be repeated by simply talking to Tiny Tina again and restarting the mission. This exploit works best during co-op play. where one person stations where Flesh Stick spawns and another at Tiny Tina. Doing so will enable you to repeat this process in quick succession until the game will no longer spawn Flesh Stick again. At this point you can run back to the start of the area, exit and return, or (faster), save & quit then reload the game. Doing so will allow Flesh Stick to respawn again.
