A Unity 3D Base defense game where players defend their base from incoming enemy tanks and helicopters using a turret-based rocket system.
ZeGunner is a 3D first-person tower defense game built in Unity. Players control a turret/cannon positioned on a base and must destroy waves of enemy tanks and helicopters before they reach the base. The game features realistic tank models, explosive effects, dynamic enemy movement, and a comprehensive scoring system.
