Here just a short review.......the most useful weapons:
1.rocket launcher-useful against crowded enemies..only has 10 ammo.
2.flamethrower-useful against crowded enemies(glitch: sometimes goes through walls)
3.flaregun-batteling demons? just use flaregun!hit them once then avoid their napalms....they will burn to death without you shooting more than 1 bullet!
4.gause rifle-pierces through enemies and destroys turrets in 3 hits!!! useful if enemies stay in a line.
5.minigun-surrounded?no problem!just use the minigun..its bullet hose technique can kill even a demon in 1 hit!
6.napalm launcher-can burn down a single tank!!!!the napalm launcher is like the flame thrower,but more advanced!it explodes in contact with any thing.has a special secret....the triple flamethrower.
7.mikor-powerful!useful if the enemies crowd together.its like the rocket launcher but more ammo.
8.arctic warfare magnum-a strong gun that can kill an enemy in one hit!!low ammo but worth using.
9.m7-a short pistol of some sort..but fires tiny missiles rather than firing bullets.can hit enemies behind walls.
10.death's scyth-a powerful tool that is used by death himself!can kill an enemy in one hit.can kill multiple enemies if they are hudled together.
HOPE THIS HELPS.
