Hi there guys,
Excellent job, this game will become an excellent one soon I guess. However I noticed there aren't a lot of weapons, items exc. My suggestion is to make much more weapons (assault rifle, rifles, pistols and so on), items (generally speaking) and armors&helmets.
Talking about weapons, I think you can introduce modern firearms like Ak47, M4, M16 and much more, and more alien weapons too like more alien laser rifle, alien laser pistols exc.
I noticed there aren't a lot of armors and helmets too. This is a pity: imagine your soldiers wearing "high tech" armors & helmet, cool uniforms (and above all, useful) and so on...
