Nemesis

From the author's website:

The Next Step in Horror Roleplaying...

NEMESIS is a dark horror game — designed to emulate the works of H.P. Lovecraft, Stephen King, Ambrose Bierce, Brian Lumley, William Peter Blatty as well as settings such as Delta Green and the Gilchrist Trust — in a roleplaying game.

It is a new, faster, more elegant way of handling both combat (the One Roll Engine) and the sanity-rending effects of horror (the Madness Meter). It picks up where its predecessors left off; creating an incredibly rich, eminently expandable game structure to be built upon.

It can handle everything from a gritty Delta Green Operation into deepest Burma or an over-the-top brawl with the Ogdru Jihad in the world of Hellboy. The system is eminently scalable and customizable.

Nemesis was refined and developed from an iteration of the One-Roll Engine as presented in Cthulhulike, an unofficial variant of Godlike. It uses the ORE for resolution and a modified version of the Madness Meters from Unknown Armies to handle character reactions to mental trauma.
