Quake's Guardian fires three green salvos from its staff in an arc. Each beam does 15 damage, making for a total of 45 per attack. The beams move very quickly through the air, thus making them difficult to dodge at close range.
If the player gets close, Quake's Guardian may hit him/her with the butt of his staff, doing around 10 - 20 damage.
Once the player has defeated the Fiend and two Ogres, follow one of the corridors to the left or right to a large outdoor room with a sealed portal. After a few moments, Quake's Guardian will appear from the ground and attack. Take cover at one of the corridors the player just arrived from and attack it. As soon as damage is done, Guardians will begin to appear from different points in the room. The more damage the player does to Quake's Guardian, the more Guardians will appear.
Continue to concentrate on Quake's Guardian whilst backing down the corridor if any of the Guardians get too close. If a normal Guardian does get in the way, it doesn't take much to kill it. Once Quake's Guardian is killed (confirmed by an onscreen message), no more Guardians will appear and the player can either finish off what remains or head for the portal when it is unsealed. The best weapon to use is the Rocket Launcher with Multi Rockets.
- When Quake's Guardian is killed, a message appears saying "..."
- This enemy is referred to as "Quake's Gaurdian" in game, though this is almost certainly a typo.
- "Player" was crushed by a Guardian
