Indie developer Kirk Lucas sent me a message on Twitter letting me know that his action tank game, Ballistic Tanks has released on Steam. The game contains over 50 maps, and 4 player local multiplayer:
Ballistic Tanks is the best tank game you've played since the 80's. It is an intense arcade shooter where you destroy tanks in a frenzy of bullets, lasers, and explosions! Play a challenging solo/co-op arcade mode or compete with up to 4 friends in a variety of multiplayer game modes.
