Challenge

Adapting CRYENGINE—primarily a PC and console engine—for mobile platforms with strict memory and performance constraints. Implemented multiple interconnected game systems (login bonuses, mounts, awakening, guilds) that needed to work reliably across diverse mobile hardware.

Solution

Implemented game systems using CRYENGINE's entity-component framework with careful memory management for mobile devices. Built server-client communication for login bonus tracking and guild management. Optimized rendering and asset loading for target mobile hardware.

Results

  • Successfully shipped mobile MMORPG on smartphone platforms
  • Implemented 4 major game systems from design to deployment
  • Optimized CRYENGINE for mobile memory constraints

Learnings

My first professional game development experience, which shaped my career trajectory. Learned C/C++ game programming fundamentals, client-server architecture for online games, and the importance of memory optimization on resource-constrained platforms.
