GodWars is a family of MUD engines derived from Merc,[2][3] created in 1995 by Richard Woolcock, also known as "KaVir".

[7] After fighting extensively to stop the illegal use of his codebase, Woolcock later released the code publicly.

[12] In 2002, Woolcock wrote a new MUD named God Wars II, a conceptual sequel to GodWars,[3] with a more personal dark fantasy universe.

[13][14] This combo system is inspired from the tabletop game Spellbinder, of which the complexity is comparable to chess and go.

The game has a large world, without rooms typical of MUDs but using coordinates, and a process for advanced character customization.
