14 Video Game Bosses Players Had To Defeat Within A Time Limit

GLaDOS (Final Battle) – Portal

When fighting GlaDOS in the final battle of Portal, she’ll fill the room with poison gas. As such you have a time limit and must solve the puzzle or die in the process. Interestingly, this is perhaps the only puzzle in the game that actually has a time limit. Given the urgency of the encounter, it makes sense.
