Borderlands

Achievement Name: Steele-Trap
During mission "Operation Trap Claptrap Trap, Phase Four: Reboot", you will enter into 3 separate arena battles. Defeating the third boss will unlock this achievement.

Stelle can be irritating because she is so fast, and she dodges alot. However, there is one thing she can't do very well, jump.

If you are struggling with steele, run to the back right of the arena from where you start, there are a couple of white blocks, standing on these will leave you pretty much invulnerable to most of her attacks. Just keep shooting, allowing her time to stand still seems to give her a chance to aim her ranged attack at you better. I beat her on level 61 in playthrough 2.5 and only got hit twice.

if you want to do this achievement, a really easy way is to get a second controller and play split screen with your character and a completely new one, and make sure the new character is the host. So player 1 will be level 1 and you will be player 2 with whatever high level you are. Then complete all the missions. This achievement is the last mission. But because player one is the host all of the enemies in the game will be a really low level, so you should be able to shoot them one shot. Youll finish the DLC is no time! and because your such a low level, the steele-trap will also be a low level so he will be really easy to kill.

When you jump down off of the ramp after following the path from killing the second trap-converted boss, Commandant Steele will enter the arena. Turn around and face the ramp then go to your left at where the wall and ramp intersect. Keep walking into the wall(you might need to crouch) and you will end up going through it. If you follow this you will end up back on top of the ramp where Steele cannot reach you, not even with her projectiles. Shoot her 'til she is dead and the chievo is yours!
