I would like some help in finding an OFP Campaign. It was probably one of the first, and it received a lot of praise for its storyline, ominous atmosphere, and mission scripting.
I believe it dealt with a group of genetically engineered people, which killed their creators. The player was tasked with investigating what happened.
A notable feature of the campaign involved the "mutants" being able to kill from a distance by launching some sort of ground-skimming "disc" at their target.
