ChromeStrike

Mixed Vehicle SciFi Roleplaying in the 22nd Century

From the introduction:

ChromeStrike is a scifi RPG based upon games like Armored Core, Chromehounds, and Heavy Gear. Players take the role of Mech Jockeys, and pilot the new war machines in the cratered battlefield of the near future. But even then, they may fight for varied causes- quite a number of these new pilots are simply mercenaries, traveling to fight in war for money and money alone. Others follow their nation's plight out of a sense of national pride. The unluckiest of them all are merely backed against the wall by hostile belligerents, fighting against those stronger and more wealthy, only for the sake of protecting their homes.
