CINERIS VEIL is a complete native Android FPS and roguelite game template built with Kotlin and Android Studio. This package includes the full editable source code, a playable Android APK, original game systems, procedural/original visual and audio assets, documentation, and tools for rebranding the project into your own game. Unlike many mobile FPS templates, CINERIS VEIL does not require Unity, Godot, Unreal Engine, or any paid game engine. It is designed as a native Android project that can be opened directly in Android Studio. Gameplay Concept CINERIS VEIL takes place inside a dark post-solar cathedral where Lumen acts as health, ammunition and visibility at the same time. Every shot consumes Lumen. Enemies drain Lumen when they attack. Defeated enemies can drop embers that restore light, forcing the player to constantly decide whether to attack or conserve resources. The included sample game demonstrates how the framework can be used to create a complete mobile FPS with progression, enemy AI, boss encounters and roguelite mechanics.
