About This Demo

Core0 blends incremental defense with auto-battling combat. Build an army, equip your core with automatic weapons, and hold against growing hordes. Turn the resources you earn into permanent upgrades, experiment with new combinations, and push deeper into the campaign.

BUILD AN ARMY AROUND YOUR CORE

Deploy frontline fighters and ranged units to protect your core. Your army fights and your weapons fire automatically. You choose the loadout, collect scrap, and decide which reinforcements to deploy as the battle unfolds.

FIND YOUR COMBINATION

Combine weapons and units to shape your defense. Clear crowds with sweeping attacks, concentrate firepower on tougher enemies, or invest in a frontline that buys your weapons more time. Try different builds and discover which combinations work together.

TURN DEFEAT INTO PROGRESS

A broken core doesn’t erase everything you earned. Between runs, spend alloy on a branching upgrade tree to strengthen your defenses and unlock new options. Return to the fight with a different plan and the tools to take it further.

HOLD AGAINST THE HORDE

Fight through two campaign stages with escalating waves, specialist enemies, and bosses. Face attacks from multiple directions, adapt to new threats, and watch your growing army clash with crowds that once overwhelmed you.

Build. Defend. Upgrade. Try again.
