Critical Mass: Patriot vs. Iron Curtain

From the publisher:

The war lasted one hour and forty-five minutes. No one remembers who fired first, but the outcome was worse than even the starkest of projections imagined. The simultaneous detonation of so many weapons attacked the planet on a sub-atomic level, scouring the atmosphere, boiling the seas, and turning forests to ash. To operate, and survive, in this new, hostile environment, powerful walking war-machines were created…

Critical Mass is a game of hard-core, heavy-hitting Mech-on-Mech combat. As the pilot of a massive war machine, you must head out into the irradiated wastes and face-down the unworthy upstarts who dare to challenge your dominion. After all, the honor of your survivor enclave is riding with you!

Featuring simultaneous play with Mech customization on the fly, the tension is sure to stay high in every fast-paced combat until the final armor plate is incinerated!
