A comedy-based mod for C&C Generals: Zero Hour, the C&C Crazy Mod adds downright absurd and hilarious units you'd never see in any other mod.
Demo General's Super Unit, the Demo Ballista fires Terrorists riding propeller-driven Hang Gliders at its targets from long range. It can salvage upgrade to do more damage per glider, and get a second glider on the launcher as well. Costs $3000 and has a build limit of one.
Credit goes to The_Hunter for his ZSU model and skin, and to E.A.G.L.E. for his Terrorist Hang Glider.
