Skip years of senior-engineering work, ship your epic battle today!
Mass Battle is the only crowd framework on Fab with an end-to-end Mass Entity Blueprint workflow and lockstep replication: prototype a full RTS/FPS/TD/Roguelike/WarSim in pure BP and ship it, while C++ devs go further with a simplified C++ API. Fully CPU-driven so gameplay and simulation stay in lock-step — no GPU readback, no sync headaches, every frame inspectable in the editor, at GPU-grade performance.
Why developers pick Mass Battle
- Kick-start: every crowd-fight system integrated out of the box
- Easy to Customize: full BP workflow or vibe-coding with simplified C++ API
- Scalable Performance: simulate over 100000 agents during a fierce combat at 60fps
- Lockstep Replication: easily replicate 10K+ agents via deterministic lockstep
