- Easy experience and weapon proficiency
Use the following trick to get easy experience and weapon proficiencies, as well as good weapons and money by selling loot from all the dead enemies. Once you reach 'The Middle Of Nowhere' area, you will eventually get the 'O Of Slaughter' quest. When do you do the quest, enter the arena, and kill all but one enemy (preferably a little one). Do not kill all enemies or the quest will end. Also, do not die or you will potentially lose a lot of money. After killing all but one enemy and collecting all items desired, exit out, and the game will save automatically. Reload your saved game, sell all desired items through one of the nearby machines, and repeat the quest as many times as desired. Notice: There are three rounds; the last one is called' Final Round'. Do not finish it if you want to repeat this trick.

- Easy experience
Notice: This trick requires at least one player with a high level (preferably between 40-50). Have the high level player(s) join your game and travel to places with high level enemies. Stay back, and have the high level player(s) kill the high level enemies to quickly increase your experience because the game has experience sharing. This is also a good way to get high level weapons and items.


Successfully complete the game, and try to be around level 40 with your character. Then, begin a split screen game with your high level character and a new character that you want to level up quickly. Find a location with a lot of enemies that are easy to kill (for example, the Lost Cave with the crabs and leveled up Skags). Make sure your high level character was saved in the area you wish to go, and load him or her as the host with the other character as the second player. Leave the low level character by the New-U Station, and use your high level character to kill all the enemies. Your new character will gain levels almost instantly. This will begin to slow down around level 28, but you will still be able to get them to around level 35 relatively quickly. You will now be able to begin a new game with your new character at a very high level and play through the game easily while collecting more and better loot. This is a great way to play with the other three characters and begin at a high level.

- Infinite loot ('The Secret Armory Of General Knoxx' DLC)
To be able to loot the armory as many times as desired with unlimited time so you can collect loot from all the crates, create a multiplayer game, then reach the 'Armory Assault' mission. Once you defeat General Knoxx, enter the armory, and get to the elevator where you turn in the mission. After turning in the mission, it will say you only have three minutes to loot all the crates. Acquire as many weapons as possible, but when you have approximately 30 seconds remaining, have everyone exit the game and return to main lobby, with the host being the final person to exit before time expires. Then, have the host create a multiplayer game again, and invite everyone back to the room. Next, travel back to the armory. Once inside, continue to General Knoxx, but instead of being sealed in the room with him, the door behind him should now be open. You should be able to walk right into the armory and have unlimited time to open all the crates. Notice: If you want to be able to do this multiple times, you must do the following. After you have looted all the crates, have everyone exit to main menu, except the host. The host must either reset his or her Xbox 360 or press Xbox Guide, and go to the Dashboard. This makes it so the game does not save the armory progress for the host. Thus, anything the host picked up during that run will not be saved. So make sure when looting the armory that only the other players pick up items, which they can then give to the host later. -From: Psychotic Elf

- Pulp Fiction reference
The names of the ships in 'That Sinking Feeling' mission are Righteous Man, Great Vengeance, and Furious Anger. Each of those names is found in the biblical lines quoted by Samuel L. Jackson's character in Pulp Fiction.

- Critical hits
It is important to try to get critical hits on enemies so you kill them quicker and get additional XP. To get a critical hit on a human, shoot it in the head. If you use a sniper rifle, it will usually kill them instantly. For a Skag, shoot it in the face when its mouth is open. This varies depending on the type. For the pups, shoot them while they roar at you. For adults, quickly shoot them while they jump at you. For the spitters, shoot their mouths while they fire their poison projectile at you. Critical hits are easiest at close range with a shotgun or scattergun.

- Army Of Darkness reference
The Boomstick and weapon description for it, 'Beyond groovy', are references to Ashley's shotgun in Army Of Darkness. The main character Ash's catchphrase is 'Groovy', and he calls his favorite shotgun 'Boomstick'.

- Easy 'You're on a boat!' achievement
Go to the dock at the farthest south point of the begining position in Treacher's Landing, and get on the little boat to get the 'You're on a boat!' achievement.




- Tenacious D reference
The 'Master Exploder' achievement name is a reference to the song of the same name by Tenacious D.

- Mad Max reference
The 'Can't we get BEYOND Thunderdome?' achievement name is a reference to Mad Max: Beyond Thunderdome.

- Duplicating items and weapons
Begin a co-op game with at least one other player. Drop the item(s) and/or weapon(s) you want to duplicate. Then, leave the game through a non-saving method, such as signing out of your profile, going to the dashboard, or resetting the system. Since the game did not save after you dropped the item(s) and/or weapon(s), you will still have them, and the other player(s) who picked them up will also have them.

- Easy loot and money
Every time you load a saved game, the chests and lootable objects restock. Save the game near a place where there are multiple weapon chests, such as in the town of New Haven. Acquire all the loot in them, then save the game. Reload the saved game, and collect all the loot again. Keep the loot you want, and sell the loot you do not want. Repeat this as many times as desired. Notice: You get more money and better loot when there are more than one player. This is best done with four players.

- Gauntlet (NES) reference
The title of the mission 'Earl needs food... badly' is a reference to the classic NES game Gauntlet. When your character was low on health in Gauntlet, a voice would say 'Blue Elf needs food badly!'

- Quick reloads
While reloading, click Right Analog-stick to melee as soon as the cartridge is removed or new rounds are being inserted, and the gun will reload instantly.

- Programmer messages
Look at the wall in the cell that Tannis is trapped inside to see programmer messages.

- Extra SDU Backpacks
Sometimes during your second playthrough and beyond, you will get an extra SDU Backpack after repairing a Claptrap even after you have reached the 42 maximum allowed slots in your inventory, which is not supposed to happen, and is a known glitch in the game. Thus, before you turn in a repair kit to rescue a Claptrap, exit the game to save. Then, turn the repair kit in to the Claptrap. If you do not get an SDU Backpack, leave the game through a non-saving method, such as signing out of your profile, going to the dashboard, or resetting the system. Then, try again until you get an SDU Backpack.

- Claptrap locations
The ten Claptraps can be found at the following locations. When you repair a Claptrap, it will reward you with an SDU Backpack, which adds three extra slots to your inventory.

- Hidden house with Rider gun in New Haven
When you get the 'Another Piece Of The Puzzle' quest (do not complete), you can go to a secret house in New Haven. When you enter the house, you take a lift down to the bottom. There is one regular weapon chest and a red weapon chest. The red weapon chest always contains the 'Rider' gun, which is a reference to the Red Ryder BB gun from the classic movie A Christmas Story. Its stats usually vary slightly each time you get one. The weapon can only be found in this house. The weapon's manufacturer is 'Gearbox' (the game's developer), as opposed to an in-game company such as Dahl, Hyperion, etc. Notice: When this location is used with the others in New Haven for the 'Easy loot and money' trick, you can get a lot of loot and money quickly.




- Easy rare weapons
Save the game near a location with multiple weapon chests, such as in the town of New Haven. Then, host a game, and have three other players join. Acquire all the weapons in the chests, then exit out of the game, and host a new game at the same spot. Repeat this process as many times as desired. You should get quite a few rare weapons using this method.

- Back To The Future reference
The '1.21 Gigawatts' achievement name is a reference to Back To The Future.

- 'Green Thumb' quest
Fast travel to 'The Middle Of Nowhere' Bounty Board. Get a car from Scooter's, and drive to the right. Look for the small shack with big plants around it. Talk to the man leaning against the shack to unlock the 'Green Thumb' quest.

- Overcomeing The Destroyer (final Boss)
Make sure you have a good shotgun with full ammunition. Destroy the purple tentacles first by shooting the spheres to prevent it from shooting missiles. Then, jump behind the red tentacles at the very back of the map. You will be next to a wall and two of the large tentacles. You can do this on either side. The eye that shoots the beam will not be able to hit or damage you. The only time you may get hit is if the purple tentacles with the spheres reappear or it does the 'energy wave' attack. While behind The Destroyer, shoot at the red tentacles. You should be able to kill The Destroyer in less than two minutes using this method.

- Weapon chest locations in New Haven


- Hidden rare weapon chest in Rust Commons West
Go to the far northwest corner (on the map) in Rust Commons West. Find the rock wall with the gun tower on top of it. Stand near the left side of the gun tower. Then, crouch and stay against the rock wall as you move down the rocks. The warning sign may appear. Ignore it, and try to move as quickly as possible. The chest is basically in front of the gun tower, under a large rock overhang. The weapons chest has a high chance of spawning rare weapons. Notice: It may require a few attempts to reach the chest. Once you get the weapons, you either must kill yourself or exit the game because there is no way to leave this area safely.




- Easy 'Sucker Born Every Minute' achievement ('The Secret Armory Of General Knoxx' DLC)
Locate the huge bullet. Find the building closest to the bullet. Follow the arrows pointing to a box with a '$' sign on it, and activate the prompt located there to get the 'Sucker Born Every Minute' achievement.

- General George Patton reference

- Extra item space
Create a second character for use in Co-op mode. When you want to store an item, begin a Co-op game with your main character and secondary character. Transfer the items you want to store to the secondary character until you need them, then transfer them back.

- Special weapon effects
There are sometimes cryptic or humorous messages found in the stats box for weapons. These lines indicate a certain effect for the weapon. The text usually gives a hint as to what the special ability does, and is also often a reference to a video game, movie, famous quote, etc. Sometimes the description relates to the Boss or enemy who dropped the weapon. For example, the description for The Clipper reads 'Don't Drop It... Might Lose A Toe.' The Clipper belongs to the Boss Nine-Toes and is the reason for the weapon's name. Notice: Some of the listed effects may not be completely accurate. All weapons vary in quality, except Eridian weapons, which are always green. Boss and quest weapons range from green up to purple, with blue being the most common. Weapons will also vary in accuracy, fire rate, ammunition count, etc., based upon what weapon is the basic model. For instance, some revolvers have two rounds; however, these revolvers generally do more damage than the revolvers that have three or six rounds. Essentially, orange weapons modify the base gun with their special modifiers.
