Create your epic battle today with ease !
Mass Battle is currently the most comprehensive crowd battle simulation plugin for unreal engine available on Fab. It is user-friendly, feature-rich, flexible, highly performant with good visual quality. This asset can be used in both code and blueprint(full bp support). Professional price comes with enhanced customer support including prioritized bug fix and customizations.

How is this framework different from other crowd-sim assets?

  • Kick-start : Integrated most of the features needed in a crowd fight, saving you years of dev time

  • Easy Adaptation: Full blueprint syncronous control over any data, you can easily add your own game logic

  • High Image Quality : GPU can focus on rendering, allowing fancy VFX and high screen percentage (ssaa)
