Panzer Combat II is a unique multi-player game using voice and a webcam-enabled computer to play a mini wargame of World War II tank combat.

You fire by placing a webcam behind the aiming unit. From there, the distance to the target is computed using computer vision.

Action inside the tanks, on the other hand, is performed on the computer screen while battlefield strategy is played on the miniature terrain. Cool, right?

The game allows players to connect with a different laptop or even a tablet.

Please note that you might need to allow Panzer Combat II firewall access or even to disable it for multiple instances. Also, the game might not release your webcam so be sure the red light is off, especially if you're a freak :)
