Crysis PVP Game

I am hoping to make a crysis in minecraft PVP game, in a completely vanilla scennorio (no mods), and because of the /effect command added in a snapshot, I have decided to start. the project. The game will be either 2 or 4 teams, with you all competing for kills before time runs out, just a simple deathmatch. will choose a loadout and a suit, the loadout effecting weapons, the suit giving you temporary superpowers, a once per life effect. Any CREATIVE FEEDBACK would be greatly appreciated, as would a kind direction to any projects already like this. The map will probably be a simple office building, or a small town. The office map may look like the one in the image, I'll get a real image up once I have an actual map going!
