One of the many titles announced at EA's recent press conference was Plants vs Zombies Garden Warfare, and the mode they are currently showing off is the 4 player co-op mode. In it you can select from 4 classes, including the Soldier (Pea Shooter), Melee (Chomper), Medic (Sunflower), and Sniper (Cactus), but along the way you can also utilize some of the other plants for your defenses as well, and I'm holding out hope that roster includes my current favorite: the cornpult. (Can you imagine the screenshots? Everybody on the field with giant cubes of butter flying over their heads. That's Craze Amaze.)
Anyway, if you want to get a better look at some of the various special abilities as well as the gameplay in general, take a look at the Dev Diary below. I've also included a recent Xbox spotlight that gives a better look at how the garlic comes into play.
By the way, I call the cactus right now! Potato mines are the best.
