If we have to have another Plants vs. Zombies, it might as well be this: still a tower defense game, reimagined as a cooperative third-person shooter.
The game supports up to 12 versus 12 plant or zombies players squaring off in mini-arenas, where each player’s plant (or zombie) employs a special class-style ability (e.g. run-and-gunner, healer, stealth melee, scout, ranged specialist, hybrid variants and so forth).
This one’s a timed exclusive, so bear that in mind: for Xbox 360 and Xbox One first, followed by Windows at some undivulged future point, followed by “other platforms.”
(Also for Xbox 360)
