- pistols have only snap shots with 40-60% accuracy and 15-25% cost to use, other way its useless
- rifles have auto cheap but inaccurate, snap same and very accurate and expensive aimed
- heavy have normal snap, no auto, and a bit better aimed, heavy and bulky (even plasma) and in general better damage
- all grenades weight 4, high explosives 9
- all tanks have auto shot but very inaccurate
