Steel Titans Case Study

Real Time Multiplayer with Photon PUN

Multiplayer duels run on Photon PUN. When two players match, Photon spins up a room and syncs every input, hit, and animation state in real time. The matchmaking layer pairs players by mech tier and rank so fights stay competitive.

Photon was picked because it handles low latency input syncing well, scales for mobile, and works smoothly across iOS and Android. Fights feel responsive even on 4G networks.

Tournament Mode on Photon

Tournaments are bracketed multiplayer events. Players sign up, get matched into rounds, and fight their way up. Photon PUN handles the room flow for each match in the bracket while a backend service tracks who advances. Winners climb. Losers drop out. The last mech standing takes the top spot.

Tournaments run on a schedule and reset regularly so there's always a new event to enter.

Complex Fighting Animations

Steel Titans uses Unity's Mecanim animation system with layered state machines for each mech. Punches, kicks, blocks, dodges, special moves, and finishers all have their own clips with proper transitions. Hit reactions are dynamic, so a heavy uppercut throws the opponent back differently than a light jab.

Combo chains read inputs in a buffer so players can string moves together. Animation cancels are tuned per move so combat feels fluid, not stiff.

Cinematic Camera Actions

When a player lands a special move or finisher, the camera cuts to a cinematic close up. Slow motion kicks in, the camera sweeps around the mech, and the impact frame holds for a beat before play resumes. This is built with Unity's Cinemachine and triggered by specific animation events.

Cinematic camera also kicks in at round start, knockouts, and tournament victories to make big moments feel big.

Powerups in Combat

Powerups spawn during fights to keep things tactical. Damage boosts, shields, speed bursts, and energy regen pads appear on the arena floor at set intervals. Smart players use them to swing momentum. The powerup system is balanced so it adds depth without removing skill from the core fight.

Diverse Mech Roster

The game ships with multiple mech classes. Fast assassins with low armor and quick combos. Heavy titans with slow but devastating hits. Balanced fighters that suit most playstyles. Each mech has its own moveset, special moves, and visual identity.

90 Level Single Player Campaign

The career mode runs across 90 stages with rising difficulty. Boss fights, gauntlets, and special challenge stages break up the pacing. Completing stages unlocks new mechs, parts, and arenas. The campaign also acts as a training ground before stepping into multiplayer.

Stunning 3D Arenas

Fights take place in cyberpunk cities, industrial yards, neon lit rooftops, and underground arenas. Each arena has its own lighting setup and props. Arena destruction effects fire on heavy hits, with sparks, debris, and screen shake reinforcing the impact.

In App Purchases

Steel Titans uses IAPs for premium mechs, upgrade packs, cosmetic skins, and currency bundles. Nothing in the IAP shop blocks progression. Players can earn most content through play. IAPs are a shortcut, not a wall. This balance is part of why reviews stayed strong.

Offline Skirmishes

For players without internet, Steel Titans runs full offline skirmish modes against AI. Same fighting system, same mechs, same arenas. This keeps the game playable on flights, in metros, or anywhere signal drops.

Combat That Feels Heavy and Responsive

Fighting games live or die on feel. Hits need to land with weight, but the controls also need to be tight. Too floaty and players feel disconnected. Too stiff and combos break. Finding that balance took a lot of iteration.

Multiplayer Sync Across Networks

Real time fighting over mobile networks is hard. Even small lag spikes break the fight. Players on Wi-Fi versus 4G need to feel the same level of responsiveness.

Tournament Flow Without Bugs

Tournaments need to handle hundreds of players, brackets that update in real time, drops, reconnects, and disqualifications. Any bug here means broken tournaments and angry players.

Heavy Visuals on Phones

Big mechs, cyberpunk lighting, particle effects on every hit, and cinematic camera angles all add up. Running this at a stable frame rate on mid range Android phones was a real engineering problem.

Balancing Across Mech Classes

With multiple mech classes from light assassins to heavy titans, balance can spiral fast. One overpowered mech ruins multiplayer. Too much nerfing makes mechs feel bad.

Custom Combat System with Tuned Feel

Hits use a mix of animation curves, screen shake, hit pause (frames where the game freezes briefly on impact), and audio stings to sell weight. Input buffering keeps controls responsive even during animation cancels. Heavy moves have longer recovery, light moves chain quickly.

Photon PUN with Input Reconciliation

Multiplayer uses Photon PUN with client side prediction for instant input feedback and server checks to keep both players in sync. If a player's state drifts, the game corrects smoothly without visible jumps.

Tournament Backend with State Persistence

Tournament brackets live on the backend, not the client. If a player disconnects mid match, they can rejoin. If they don't return in time, the AI takes over so the bracket keeps moving. Match results are written to the backend before the next round starts so nothing gets lost.

Performance Tuning for Mobile

Mesh LODs, texture atlases, baked lighting where possible, and Unity's URP keep frame rates stable. Particle effect counts scale down on weaker devices. Cinematic camera shots are pre-baked sequences so they don't add runtime cost.

Data Driven Balance Tuning

Mech stats, damage numbers, move speeds, and special move cooldowns are all stored as data, not hard coded. The team uses match analytics to spot imbalances. Win rates per mech are tracked, and balance patches go out as soft updates without forcing a new app build.
