I like the grass animation, looks realistic. Ideas:This would be hard,but moving realistic clouds. *none at night* Do your day and night systems. Add ponds. Oh,and I favorited this so I could check back at it.
My ideas:Some more primary guns. More maps. More medals. More killstreaks/skills. Oh,and if you can,more players (max 16). Oh,keep making great games! Otherwise 5/5.
I didn't think anyone would notice stuff like that. Gratz. :P
