Zero Point want to explain their (frankly fairly impressive) Unity-powered first-person shooter, Interstellar Marines, to you. To do this they have created a four-minute trailer, which shows off the game in action, and talks about how you can support their attempt to make a full-blown FPS without the resources of a big studio. It's fun. It's even got some jokes in. Go take a look.
We'll be talking to Zero Point about their project quite soon.
