Might be time to stop calling Warhammer 40,000: Space Marine a Gears of War clone. The team at Relic Entertainment took the wraps off of the upcoming game's combat system today, revealing that Space Marine is the polar opposite of a cover-based shooter.Whether you're wading through Orks with your Chainsword or taking them out at range with a Plasma Gun, Space Marine is what the developers refer to as a pure combat experience with a singular goal: "unleash visible violent death." See for yourself:Warhammer 40,000: Space Marine is being developed for the PlayStation 3, Xbox 360, and Windows PCs. The game is set to ship sometime in August.Looks fun, but also like it could fall into Dynasty Warriors, button-mash-hell territory. Hopefully there are a handful of additional gameplay elements that will mix things up. We'll find out soon when we see the game at E3.
