Team Deathmatch is similar to the classic game mode from other games. In this mode, players are broken into two teams. The first team is Marines and the second are the Xenomorphs and after a round, they switch teams so that each team gets to play both sides.
During a round, the goal is to kill as many of the enemy as is possible. Each round has it's own winner and at the end of the game, all kills are tallied from both rounds to decide who wins. It isn't necessary to win both rounds to win the match if your team wins by a significant margin in one of the rounds
