at stage1.
if you need evolvepoints/credits with fun, fast and easy kills, i think best ways to get them is using rifle or dretch (or other stuff if u like)
reason1 about rifle: enuf good accuracy,
reason2:(enuf) good clip size,
reason3: (if good player, easily) can kill dragoon and other aliens(i dont think it can kill tyrant

)
reason4:good group of rifle mans pwn easily...(but can still be killed easily though

)
reason1 about dretch:small
reason2: fast
reason3: VERY lethal if you know how to use it well
reason4: headbite from the floor
reason5:can kill helmet humans too (reguires luck/skill)... can kill battlesuit players too(reguires luck/skills too)
reason6:can go into small places and hide there

so..... what do yea say? d(+_+)b
