Teams is a game mode putting players into different teams, up to 7. The more players/bots, the more countries per one team, but the game still limits the number of bots in the world to 500 or so.Template:Fix/category
You get assigned a color, and play together with your color to beat the other teams.
Unlike Free for All you do not get to break your alliance or betray them. However, it is still possible to do team damage using missiles.
In the team game mode players often decide to pool resources, like sending troops to their allies on the front line or send gold to be able to afford defense posts and later on in the game MIRVs.
