and throughout the whole game ive only found 2 alien weps... done every mission and everything.. wut bout the rest of ya?

Level 50... found about 30 of them. They are usually either level 28 or 48.
Most are bad though, no point in using them.
Only ones I found that are decent are the shotgun and rocket launcher versions.
You should also use the Borderlands topic to ask questions instead of a new thread, just letting you know.
