Gaia Frontier: After Contact

First contact was not a greeting. In the aftermath, the Gaia Defense Initiative hands you the one weapon that still matters: the last orbital turret standing between Earth and everything descending toward it. Gaia Frontier: After Contact is an arcade planetary defense shooter built around a single, escalating hold-the-line loop — you, a curving horizon, and wave after wave of whatever the sky sends down.

Combat is fast and readable. Aim with mouse or touch, switch between the Cannon, Gatling, Laser and Missile as you unlock them, toggle AUTO fire, and spend limited-charge powers — EMP, Orbital Strike, Frag rounds — when a push outguns you. Waves arrive in five-sector cycles; crits, combo chains and harvested credits make every run feed the next. Your planet's hull is the only score that matters: when it breaches, the run ends.

Between runs, a full meta layer keeps the war going — Boss Rush and Endless modes, an in-run Shop, Vault and Quests, commander ranks, daily streaks, cabinets and the Top Commanders leaderboard, with cloud saves bound to your Defender ID. Runs are short, the ceiling is high, and it all runs in the browser — desktop or phone, nothing to install.
