Casting the player in the role of a bow-wielding dude on the prowl for Triassic-era steak, The Stomping Land is one of the more original concepts to land on Steam Greenlight. Throw in co-operative multiplayer, survival elements and the ever-present threat of being devoured by a giant carnivorous lizard and it's hard not to keep one's wallet/purse in their pants.
Sadly, the game is still in heavy development, so your bank account is safe for now, though the prototype video above shows a game that already has a lot of class. Basically, you run around taking out tiny dinosaurs, carving them up for sustenance and trying your best not to die. The only problem is gathering takes time and your puny human anatomy is no match for head-sized teeth.
That's why you can band together with other players, set traps, create camps and generally toss your lot in with your arrow-firing compatriots. Co-operation is "highly rewarded" though it's unclear whether this is from natural benefits alone or additional game-y bonuses applied on top.
Given the extremely low-tech nature of the gameplay, it'll be interesting to see how the developers ramp things up as the player progresses, but I get the impression your avatar might be very disposable, promoting a play style that rewards risk-taking.
Note that The Stomping Land is in the Concepts section of Greenlight, so your votes don't contribute to it getting on Steam. It's merely a way for the developer to gauge interest.
