THQ has announced that everyone who buys Metro 2033 for PC on launch day in the UK will also receive a free copy of Red Faction: Guerrilla.
The game is due out on PC and Xbox 360 on 19th March.
Red Faction: Guerrilla came out on PC (and console) last year. It "only" picked up 7/10 in our review but was still loads of fun, largely thanks to its brilliant destructible environments and openworld approach.
Metro, meanwhile, is a post-apocalyptic shooter with RPG and horror elements in which players have to fight through the Moscow metro tunnels.
