Bosses are powerful enemies found at the end of missions as a challenge for the player to defeat. They have high health and powerful attacks, making them much more difficult than normal enemies.
Bosses must be defeated in order to progress into the game's storyline and unlock the next mission. Defeating each boss awards the player with a quest completion, sometimes with rewards (e.g. defeating Dreadwing awards the processor).
