The player has made a mistake in the past and has to face the consequences now ... through suffering! The punishment comes to the player in 4 parts and one additional final part. This is like nothing you have ever played before.
+ Unique boss fight
+ Some interesting puzzles
- Boring combat, you only face vortiguants and headcrabs (and some few grunts)
- Repetitive
- No challenging at all (except for the repeat part)
- Some bland maps
- Trial and error
- Nothing to do with quake, despite the name...
