VariaBULLET2D is a complete 2D projectile management system for Unity. It's extremely flexible, intuitive and simple to use whether when visually constructing emitter patterns in the editor or when extending the code from any of the 20+ core shot behaviors to create your own unique shot types. The system is easily integrated with existing projects or you can use any of the 40+ included scenes as a foundation for a new one, complete with character controllers, collision management scripts for dealing damage, destroying objects and instantiating explosions and a lot more.

All game types and orientations are supported: vertical, horizontal, omni-directional, bullethell, sidescrolling, top-down, puzzle, physics, non-physics... basically any 2D style game that requires projectiles! The system is precisely the same whether constructing relatively simple player, enemy or weapon shot patterns or wild & complex clusters which fill the screen. Since the underlying behaviors are completely written in Unity, there is no added overhead and with the added efficiency of optional object pooling you can get thousands of concurrent bullets without sacrificing FPS.
