I have tested this with up to 4 players, but I have it set to 6 players since the map should be more fun that way (let me know if ANYTHING goes wrong or if you find ANY bugs)
Also I have turned off gun recoil for enemy players for now, since it can cause some problems I have not fully worked out yet...

A lot of the gun sprites are not finished yet (the art in general is mostly placeholders)
I realized after making this that various aspects are inspired by the Flash game Strike Force Heroes 2 (and some of the item features and gun mechanics are inspired by Halo Combat Evolved / CE)
