Rann

About

Rann is a 2.5D fighting game for Android, iOS and the browser, and players on all three can fight each other online. It has six characters, each with its own mechanic: Kael has a rage meter, Mira switches between Tiger and Crane stances, Ravan the demon king has a Dashanan meter, Aswashthama is a fast rushdown fighter, and Tulbul Pandey and Bogembo are Bollywood-style characters. Play locally, against the CPU, in training mode, or in ranked matches online.

Highlights

• Cross-play between mobile and browser
• Rollback netcode that holds up on mobile
• Glicko-2 ranked matchmaking
• Training mode with frame data & hitboxes

How it works

1. 1All fight logic is a separate, deterministic, integer-only simulation with no state in 3D nodes, animations or physics. Online, the game predicts the opponent's input and, when the real input arrives, rewinds and replays frames in a few milliseconds.
2. 2Netcode runs over ENet (UDP) on mobile and desktop and WebRTC in the browser.
3. 3Each character's special mechanic is a pluggable StyleComponent, so adding a fighter doesn't mean rewriting the combat system.
4. 4A Fastify + PostgreSQL server handles sign-up, email confirmation, password reset, profiles and ratings. Ranked matches update each player's Glicko-2 rating, and guests can play everything unranked.
5. 5Training mode has frame-data and hitbox panels, and the dummy can record and play back inputs.

Why it matters

It brings a fighting game with Indian-mythology and Bollywood characters to phones and browsers, with netcode that holds up on mobile connections, fair skill-based matchmaking and real training tools for serious players.
