False Dawn is set a number of years after the events of Quake 4, where you assume the role of the Most Unexceptional of a new breed of soldier, the Stroggified Marine. You can go where no regular human can and have been called upon to save humanity from the threat of a mysterious new super weapon developed by the vicious Strogg!
The gameplay and story in this mod one-upped Raven themselves massively. The Stroyent health mechanic is really cool and the level design is spectacular for a fan project. I agree with the other reviewer that I'd love to see a follow-up to this.
