Raid Rush: Tower Defense TD
After the midcore MMO project, I joined Panteon’s live tower-defense hit Raid Rush as a client developer in 2025. It is a tower defense game with a twist: you arrange not only your towers but also the roads the enemy waves march on, blending strategy with luck-driven mechanics. The game has been live on the App Store and Google Play since 2023 and holds a 4.4★ rating with thousands of reviews.
Working on a live game with a large player base was a different kind of challenge from greenfield development: every change ships to real players within weeks, behind feature flags and config switches, with save-data compatibility in mind.
My Contributions
- Flash Events: One of my main areas — worked on the redesign of the time-limited hero flash event system: purchase flow, event currencies on hero upgrades, light effects across the lottery, dice and fishing event screens, timers and event-end lifecycle handling.
- Shop & economy rework: Migrated the legacy chest cooldown/timer system to the new cost system — timer products, booster item cost views, IAP config sync — and removed the old systems safely.
- Save-data migrations: Implemented and fixed save-data migration steps so reworked systems stayed compatible with millions of existing player saves.
- Live-ops & clans: Added new analytics events for the clan system and GM analytics for the Boss Brawl and Spinfinity events.
- Gameplay & content: Hero skill fixes (thunderstrike controller), tower stat cleanup, and rigging support for new units like the Hoverbike (bones, props) in the vertex-animation pipeline.
Tech Stack
- Engine: Unity 2022 LTS, C#.
- Performance: Vertex Animation Textures (VAT) with baked meshes for rendering big enemy waves cheaply.
- Live-game infrastructure: Save-data migration system, configuration generation pipeline, automated test suite, I2 localization, IAP and analytics integrations.
