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

If you are running low on money and need ammunition, go to Southern Shelf and buy some there. What used to be over $500 to fill your guns now costs about $100.

Play through the Story mode all three times then return to Normal mode with your character of choice. Carefully examine all the non-level specific challenges to see what is required to complete level 1 of each. Note: Some of the undiscovered challenges do not unlock until you reach a certain area in the game or with weapons until a particular weapon's level 5 challenge (i.e. "Open Wide!"for the shotgun, completion of which unlocks the previously undiscovered Shotgun Sniper challenge) have been completed, which can be a grind even in Normal mode. The easiest way to complete the level 5 weapons challenges is to spend your time exclusively in Southern Shelf and Southern Shelf - Bay where the lowest level enemies spawn. Additionally, just because a weapon challenge has not unlocked yet does not mean the game is not counting progress towards completion if you sometimes do what that undiscovered challenge asks. Also, it should be noted there are 114 non-DLC and non-level specific challenges that need to be done and at least three of them require two or more players.

To easily kill Terramorphous the Invincible, wait to accept the mission "You. Will. Die. (Seriously.)" until you have a level 62 or higher character and your current playthrough is inUltimate Vault Hunter mode. Then while in Sanctuary in Normal mode, accept the mission from Dr. Tannis inside the Crimson Raiders HQ. Next, travel to Thousand Cuts and follow the mission marker to the entrance to Terramorphous Peak. Pay the 8 Eridium fee to access it and Terramorphous. Finally, summon Terramorphous with the longhorn. Within five minutes you should have Terramorphous killed, and if the profile being used kills him for the first time the achievement or trophy will be earned. Also, at the very least you should gain one Orange (Legendary) item in the form of a "Slayer of Terramorphous Class Mod.

Enter The Fridge and turn left immediately to enter the next zone, "Fink's Slaughterhouse". This is the first arena. Accept the quest from Fink and complete all five rounds earn "Went Five Rounds" and a unique gun. If you have difficulty winning all five rounds, progress in the storyline until you are a higher level and try again.

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.

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.

Press Up(2), Down(2), Left, Right, Left, Right, B, A, Start at the title screen to unlock the "Extra Wubs" option at the "Gameplay" section of the "Options" menu. Note: Extra Wubs has no effect in the game.

One of the rifle challenges is called "This Is My Rifle", which is a reference to one of the movie's more memorable lines. The reanimation station states "You will not die unless you are told" after reviving you, which was also a line in the move.

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.

During the "Clan War: End of the Rainbow" side mission, once you have followed the Bagman to the Holy Spirits' cash stash underground and are attempting to kill him, he will occasionally teleport. During this time, non-lootable gold coins and paper money resembling the money used for playing the board game "Monopoly" will appear momentarily. This is most easily noticed if you are trying to attack him from close range.

There is a quest Patricia Tannis will give you called "Splinter Group". The first step is to pick up some "bait" from Mad Moxxi. This "bait" is actually pizza and Patricia will say after you pick it up that they love the stuff. You end up going into the sewers, which then is a hideout of the runaway mutants. Leave the pizza on the table and get ready to fight four "brothers" who talk like the four talking turtles. After you defeat them. you will go further and can choose to just leave and forget about the puzzle in the final room, or try to finish the puzzle to turn five red lights into five green lights. Once all lights are green another mutant will will come out of hiding and attack you. All five of these mutants does flips, Rolls, and jumps just like a ninja would do.
