Core Sentry
A downloadable game for Android
Core Sentry (Alpha Gameplay Prototype)
Welcome to the early gameplay prototype of Core Sentry!
This is a raw vertical slice focused on testing core combat mechanics and meta-progression loops. Built by a solo indie developer, this prototype is released to gather initial community feedback and gauge player interest.
⚠️ NOTE: This is an early alpha build. The game currently COMPLETELY LACKS SOUNDS AND MUSIC, and some visual assets are temporary placeholders. The main purpose of this release is to test weapon balance, wave difficulty, and upgrade upgrades.
🚀 What's Inside:
- Protect your core platform against advancing asteroid belts, high-speed comets, and evasive sniper ships.
- Accumulate meta-tokens to unlock 4 distinct turret modules in the shop (from the classic Alpha Core to the blistering fire rate of the Strike Repeater).
- Buy passive technology skills to trigger chain lightnings, automatic smart rocket salvos, or override systems with the ultimate Pilot Protocol.
- Watch your battle score actively drain and convert into hard meta-currency right on the game over screen.
📱 Current Controls & Compatibility
This specific build is compiled strictly for Android mobile devices and is optimized exclusively for touchscreen controls. Additional platform exports and gamepad support are under layout and will be integrated into future major update cycles.
