Generals Alpha is an OpenRA mod that recreates Command & Conquer: Generals on OpenRA engine as much as possible but using Red Alert and Tiberian Dawn artworks.
Some difference from the original one from General:
when firestorm kills unit, the kill will be granted to the last infernal cannon who trigger the firestorm (in original game, the kill doesn't grant to any)
Mig's fire can add fuel for Infernal Cannon, and vice versa.
