Cheat: Gain Levels and Money Before Entering Borderlands

In the first scene, when you're getting the tour with the scrap robot, follow him all the way through to the small campsite with the car up on the lift next to the burning tires. Collect all the loot (guns, money) along the way and kill all of the guys. Once everyone is dead simply pause the game and go to exit. It will save your character (level & loot) and start you at the very beginning upon loading your game. You can repeat this as many times as you'd like!

Cheat: Duplicate Items

To make a copy of any item you'll need a cooperative partner in a multiplayer game. Simply drop what you want to make a copy of on the floor, exit the game without saving, leaving your friend free to grab it. When you return, you'll have your copy of the weapon still, and your friend can hand you the other. This works on all guns, shields, and class mods, and can be done as many times as necessary.
Unlockable: New Game +

Complete the game to unlock a New Game + mode. Some items and stats will carry over into the new game and enemies will be tougher.

Hint: Reload Quickly

Watch your reload animation. As soon as the cartridge is removed (or rounds are being inserted), click the Right Stick (melee) and the gun will finish reloading. Do this to save time and possibly your life.
Hint: Easy Escape After Defeating Sledge

After you've defeated Sledge (and collected the artifact), exit and save your game. When you start you're game again you'll begin at the save point at the very beginning of the mission. This way you don't have to backtrack on foot and you'll save a lot of ammo too.

Hint: Item Storage using an Alternate Character

An effective, but annoying, way to store your extra stuff is to create an alternate character that is only for holding your extra stuff. Just create a new character, load a co-op game with both your main character and your new level 1 character and give them the items you want to put up. Log back in to your level 1 character and give the items back to your main character when you need them. This can be really useful when you find weapons and items that are above your level, or are saving them to give to a friend's character.

Hint: Easy 20,000 EXP

As soon as you are able to get a vehicle, find a safe place away from enemy spawn points... 

If you dont have mods or any buddies that want to help you take don Craw the invinc, then heres and easy way.
When you enter his upper lair, youll notice him, minions, and 2 rocky objects.
Your gonna want to run tp the second rocky structer, (the one on the right, its sort of like a tunnel), and avoid enemy its at all costs. Now, your gonna want to wait for Craw to burrow under ground backwards. When he does this, make sure you have full sheild/HP. No when he flies up in the air, hitting you up as well, look down for the rock platform. Try to land on it.
Now this may take a few times, but its worth it.
Once you get up there, you can shoot all his critical locations depending on where he stands.
THe only attack he can hit you with is the spit balls, which cant knock you down, but try to avoid them.
His minions cant hit you either.
But make sure you have lots of ammo.
I brought an eridian rifle just in case. Unlimited ammo, you know?
I defeated him when i was level 54 this way.
If your still having trouble, add me and ill help. On alot. GT: Viral End.

Once you hit level 5 and get the Berserk action skill, you can exploit a glitch that will allow you to constantly be able to move as fast as you would if you were going berserk while still being able to use all your weapons normally. 1. Activate the Berserk skill. 2. While Brick is doing the beginning hand animation he does at the beginning of Berserk, quickly hit the Back button to get to your inventory. This will cancel the Berserk prematurely. You must hit the back button before the beginning hand animation ends or it won't have any effect at all besides just canceling out the action skill. 3. If you did it right and you exit out of the inventory, you will walk at running speed and run even faster! To return to normal, just activate the Berserk when it recharges again and wait until the hand animation is done. Once it is, just wait or exit out of Berserk by going to the inventory and it will be set back to normal.

If you play as hunter and got the exlosive artifact for him go in the backpack press A on explosive artifact onec you do it go to perks in the top left corner ther is a dimond there press A. press A onec more on explosive. (works on all artifacts) ;)

First,go to t.k baha's house. there will be a tower to the left of his house. run and jump onto the first brownish line on the tower. when you land on the line, you can keep jumping up the tower then you will be on top of the tower. NOTE: DONT crouch or you cant stand back up until you walk off of the tower.

All you have to do to keep the berserker's speed is activate berserk mode and then pull up your inventory within ten seconds. If you did this correctly then you should be running really fast until you die, change areas, or pull up your inventory again. I am not sure if this works on any dlcs or patched versions. This way of doing this is less lethal and time consuming and constant.

This method will require two players and two profiles. One of the players needs to be a level 45-50 hunter with level 5 of the shield bypass skill. Just take the new character to the eridian promontory on play through two and have the high level hunter kill as needed. The new character should hide and run if the need arises. Though after you kill everything there you will have to leave the area to respawn the enemys. (for obvious reasons this trick works best if the low level player is a siren:-)

This works better with soldier class or in co-op get a car and drive it to the entrance get out and go up the baord walk drop in destract itad lead it where you enterd keep him there when you die go to the station but instead of geting a car teleport to drivers seat drivers seat and go to entrance hole but dont go in if you get there fast enough skagzill will be right below just keep shooting until he dies it may not work at first just keep trying if you have soldier class and skagzillas not under lead him there with the turret
