Frontline Chaos is a Total Conversion mod for C&C Generals Zero Hour. It will replace the original sides, and introduce two brand new armies: Revenant and Legion. The mod's goals are to supply a completely new story, including campaigns for both sides, and a balanced and fun multiplayer experience.
Revenant's latest defensive toy: the Thunder Cannon. Or as I like to call it, the "big fat f*ck-you cannon" (pardon my French) =P
In essence an artillery piece which fires in a low angle, doing massive damage against everything slow (or dumb) enough to get within its pretty long range. Best countered with either artillery of your own, or air units.
It must be unlocked first via a Gen Point.
