Overview
Oniro Army is the tower-defense entry in the Oniro universe. Instead of pushing an army forward as in Oniro Battlegrounds, you build and upgrade defensive lines and hold back escalating waves of incoming units. Same doodle-art world, inverted verb: defend instead of attack.
How it works
The game is built in Godot 4 for mobile. Waves scale in size and difficulty over time; the core tension is spending limited resources between placing new towers and upgrading the ones you already have. Because it is a companion to Oniro Battlegrounds, it shares the same underlying project structure — Godot client plus a containerized Nakama backend — so the two games can eventually cross-pollinate progression and cosmetics.
Why a spin-off
Building two games on one shared stack is a deliberate content strategy. Tower defense and battlefield RTS are different enough to feel like separate games, but similar enough to reuse the art pipeline, the unit definitions, and the whole server/deploy setup. That lets a solo developer ship twice the surface area for close to the same infrastructure cost.
Status
Wave-based defense, tower placement, and upgrades are in and playable on a mobile build. Work continues on balancing the escalation curve and tying progression into the wider Oniro universe.
