You love mech narratives and shooting enemies out of the sky? Set on a futuristic Earth that is nearly destroyed, the robots in Project Nimbus are humanized to fight in the skies and defend their territory in World War III.
The game has three modes: Campaign, Survival, and War. All are similar to each other. Campaign is the main story mode where you take control of various mechs and go through battle after battle while real people tell you what to do.
