We're only a few days away from E3 2010 and there are plenty of co-op games coming out that we're excited to hear about. While High Moon Studios, developer of the three player co-op action title Transformers: War for Cybertron, isn't slated to make an appearance at the expo as the title is only a couple weeks away from release, that's not stopping them from releasing an official E3 trailer. Really giant robots, space laser beams, Peter Cullen, and more are shown off in this latest video for what we're hoping will be not only an awesome co-op game, but an awesome Transformers game as well.
