MicroVolts, a third-person multiplayer shooter, has been rumbling along in beta for a few months now. It’s a hybrid of TF2 and MicroMachines, teeny little toys waging war in your back garden. Why do they fight? For battery resources, of courses. And for supremacy in the Micro World. Which is presumably just the world, but seen from lower down. It’s entering its second closed beta on the 28th, accepting applications for that now. And there’s a fresh new trailer of the frantic action to see below.
