First off this is two games in one, so that's a steal, But second off, The games themselves are badass FPS/melee game, Melee is less like condemned and more boxing, trying to make combos and such, and lots of stealth, which is also badass.
Did I also mentioned that Vin Diesel voices Riddick in both games?

These games are absolutely Great, Although I do wish there was perhaps a remake so that then they could improve upon the combat.
