Crossplay

Is Battlezone Combat Commander crossplay?

Battlezone Combat Commander is only released on one platform, so there is nothing to cross-play with.

Steam's own store page lists cross-platform multiplayer for Battlezone Combat Commander. That confirms it exists, but not which platforms pair up.

"A mysterious alien force threatens humanity itself. In this galaxy-wide war, you are in command of the resistance. Leading from the front, you take to the battlefield in thrilling first-person combat, piloting futuristic, customisable war machines including hover-tanks, colossal mech walkers, lightning-fast mortar-bikes and more."
