Crash Tycoon

A physics-driven mobile runner built in Unity 3D, where lane-switching dodges end in full ragdoll crashes and chain-reaction vehicle pileups.

The problem

Mobile runners need tight, responsive controls, but physics-heavy moments like crashes and pileups tend to feel either scripted and fake or too expensive for phone hardware, since realistic physics and a steady frame rate pull in opposite directions.

The solution

Crash Tycoon uses custom physics-based lane-switching during play. On impact, the character controller switches seamlessly into full ragdoll physics, so every crash plays out differently, and collisions calculate impact forces to drive dynamic vehicle pileups. Heavy profiling and optimization keep all of this running smoothly on mobile.

Key features

Custom physics-based lane-switching movement
Seamless transition from the character controller to full ragdoll on impact
Collision system that calculates impact forces for dynamic vehicle pileups
Localized visual effects triggered by collision events
Modular, extensible power-up system for gameplay modifiers
Optimized for a steady frame rate on standard mobile hardware

Results

Built a seamless handoff from the gameplay character controller to full ragdoll physics mid-run
Profiled and optimized for mobile by cutting draw calls, managing object instantiation, and tightening scripts to hold a steady frame rate
Designed an event-driven collision architecture and an extensible power-up system, so new effects and modifiers are easy to add and test
