great game
take all the bugs mentioned and some suggestions and fix em. Then improve and reamp and launch multiplayer right before summer ;)
1 bug: able to use adrenaline after death
AI can be improved. Allows option of 'smartness' from retarded to elite.
more specific, how well they move, accuracy for shooting, and priority logic. (like do I search for weapon spawn if I'm low on ammo or deplete first and search? When should I find a health pack? 40% of health? 20? 5? Etc, complex, but more fun without multiplayer. ;)
above is not necessary but can make the game more fun.
The ingame GUI can be improved. When I go to certain area the foreground objects would cover my sprite obstructing my exact area. So, use alpha to render visible of the player when going behind objects.
I hardly looks at the minimap since I'm focused on the action and the map is somewhat small. Try make it more useful and tactic related.
when went over a weapon spawn of same type held in your hand, the extra ammo should add up
add powerups! super armor, double damage, etc.
very nice for map editor. would be nice if you can test in real time ;)
