Coldest is an online multiplayer Mech combat game. Two teams battle each other on a variety of maps in an attempt to destroy each other's base(s). It is possible for there to be more than one base per team, but only one needs to be destroyed in order to win the game. Each player selects a mech, weapons, and an item based on the amount of salvage that they have. Both teams initially spawn from their base, but may place additional spawn points at strategic locations as the game progresses.
