Last week you may remember the Primal Carnage beta keys that we were handing out on Gamereactor. With that in mind, it may be of interest to some of you to know that the game has now launched on Steam, and can be downloaded here. It's priced at £11.99, and features a fight for dominance between mercenaries and dinosaurs. There are 10 playable classes (mercenaries play in first-person), and a nice selection of dinosaurs (played from a third-person perspective) that can be taken into battle.
