Arena

 is a commonly known style of Player versus Player team-based game play, and is used in quite a few MMORPGs and first person shooters. In Star Trek Online, players must eliminate a certain number enemy combatants. Once one team has eliminated a required number of enemies, it wins the game. Players that are eliminated are allowed to respawn after a timer.

The Cracked Planetoid map is also available as a small craft-only arena.

Tactics
Stay with a group of allies and use the environment to cut enemy line of sight if needed. In space don't let yourself be cut off from your team by the enemy -- if this does happen you will be attacked and you will probably be destroyed.
