It's another week, another set of deals for Xbox Live Gold members, and for fans of co-op, they are especially good deals at that. First person brawler Zeno Clash is down to a mere 800 points, while twin-stick shooter Alien Breed Evolution will set you back half that at 400 points. Both together are a decent bit of co-op alien killin' for less than the cost of a couple movie tickets. There's even a deal on the co-op "Swarm" map pack for Aliens Vs. Predator, at 400 points, so if aliens alone aren't enough, toss a few extraterrestrial, dreadlocked hunters in for good measure.
