Amatuer Fps Loadout

[Alcatrazz]

Me and my friend are designing a FPS for PC as a sort of a spare-time project. It involves 2 teams: Government, a sort of generic space marine type, and Rebels a ragtag bunch of misfits using cheapshit guns and converted construction tools. These are the weapons per team; light, medium and heavy pistols, machine pistols, PDW, Assault rifle with underslung GL, Scoped assault, shotgun, sniper, Grenade launcher. Please, tell me what you think of the weapon selection. Keep in mind that these are only guns I found 3d models for, and thought were cool.
Also, Pretend that Ruger is like a 45 acp instead of a 22lr.
