Free this weekend, in your Steam library you will find both Primal Carnage and Orion: Dino Horde ready to download for a free weekend trial.
In Primal Carnage a team of soldiers will compete in first-person shooting action against another team of human controlled dinosaurs. Not only will the teams of soldiers choose from a variety of weapons, the dinosaur team can select a variety of dinosaurs both flying and on the ground.
If Primal Carnage doesn't feel quite right, ORION: Dino Horde, the re-release for ORION: Dino Beatdown, allows for both first-person and third-person shooting with slightly more futuristic weaponry and over 50 weapons and gear to create classes from. ORION: Dino Horde allows the dinosaur team to choose from 9 different dinosaurs, ranging from the T-Rex to the Stegosaurus. Also in Dino Horde you can drive vehicles in the large, open maps.
Both ORION: Dino Horde and Primal Carnage will stay in your library until Sunday at 1pm PDT/ 4 Eastern. If your free trial convinced you of purchasing either game, you can purchase Dino Horde for 25% off until Monday morning and you can purchase Primal Carnage for 50% until June 6th.
