The Las Gun is perhaps the most powerful stage 1, and even stage 2 gun. It does almost the same damage as a shotgun, is fast, and automatic. Sure the prifle can do lots of damage, but it is slow. The best close range tool at s1 is the painsaw. 3 Humans with a painsaw, 1 with a shotgun, and 1 with a lasgun can take down the whole alien base, with the whole alien team being goons (i know, it happened yesterday on killaz). The most powerful close range gun at s2 and possibly even s3 is the flamer. You can toast most aliens very quickly if you have skills, and do not spam. There are a few combos that are nightmares to any alien. They are a helmet & armor with a flamer combo, a bsuit with a chaingun, and a bsuit with a painsaw. A psawing bsuit can kill tyrants like that (snaps fingers).
