After a few practice sessions it was clear we'd need to outnumber our opponents in co-op to have a chance at winning. Perhaps a little unfairly we took on the Easy AI with a 2 to 1 ratio with Locke, Mike, Jason and myself all teaming up as one of the three in game factions. And while we all managed to figure out a strategy specializing in different unit productions to maximize our war effort, I'm not so sure the AI ever worked together to actually try to defeat us. 

Take a look at some of the Cartel's finer points.

The US Army has access to the LGM-118 Peacekeeper missile which can be further upgraded to be faster and have a larger blast radius. The Chimera, on the other hand, have the Omega Blitzer, a multi-shot long-range rail gun with a wide spread. Last, but certainly not least, the Cartel possess the Thor Control Center, which can rain lightning down from space on enemy bases, featuring high intensity damage with a narrow spread. You can see all these super-weapons in the trailer below:

And let's be honest, who would want to do that?
