Em@il Games: X-COM is a turn-based game played over email (optional one computer hot seat) loosely based on the original X-COM game. The units and weapons are similar. The graphics are basic but clear. The major difference is the game-play of course, which is very simple. Each player controls a squad of randomly assigned troops, you have limited action points and move/fire options. Whoever kills the other squad wins, no research, no campaign type options, just single map games. The players can select the side of the conflict (X-COM troops or Alien forces) and one of five available mission environments.
