Ive recently started playing borderlands, i need two more trophies to Plat it, getting to lvl 50, and collecting all the backpack SDU'S but i think i may have sold one.....as im quite sure ive saved ALL of the claptraps,anyway so i was wondering is there any i can save one on the DLC if i bought it and will that  get me the trophy...or do i really have to start again? or can someone give me one online?

come on someone on here must be a borderlands veteren

Im going to assume your on your second play through...I wasnt aware you could sell the SDU's. hmm... I believe in the downloadable content there are a few claptraps you can save... not entirely sure though. The best advice I can give in search online and make sure you've found all the claptraps on both play throughs. Sorry man.

No worries dude, im pretty sure i have saved all of them wen't through 2 of the guides but i will look once more, i may be mistaken, I had done one as a co-op, not sure weather that makes a difference or not

dlc claptraps work on 360 towards the achievement. the dlcs are great though, id recommend them all except moxxis which is painful to play.

Yeah... I was really enjoying Moxxi.... until I realized that the five rounds I played were in fact just one round...

They gotta be kidding with that!

You'll find claptraps to rescue fairly early on in General Knox's expansion so donn't worry! The other expansion packs aren't done yet (on my part) so I don't know about them.
