How to: Final Quake Monster
Question: How do I kill final moster on the last level of Quake?
Answer: look around the level and try to understand how it works. Pay especial attention to teleporters and flying objects. If you are still stuck, read the next paragraph.
Look closely at the flying spiked ball - when you pass the teleporter at the end of the path, you are teleported to the location of the spiked ball. Read next paragraph if you are still stuck.
Ball enters the monster from time to time.
Think about telefragging.
You have to enter the teleported when ball enters the monster - you will then be teleported inside of it and instantly kill it.
