If you don't mind Origin....
Dead Space 1: (I think you can redeem it within the month until the offer expires, but you keep
the game on Origin)https://www.origin.com/gbr/en-us/store/dead-space/dead-space/standard-edition
and there's a free fighting game on GOG too (called The King Of Fighters 2002).
Warning, Dead Space is an 18+ game.
