Your queen follows the mouse. Hold the mouse button to send every ant to attack at the cursor - they ignore food while attacking, and she keeps following at half speed. Food sources drop around the arena - move to find one and a scout brings the trail home, then your ants march it. Hold Space to feed hard: your whole colony pours onto the trail. But the trail and the source are visible to everyone, a feeding queen walks slow and doesn't heal, and feeders are marked for raiders. Ants fight harder in groups.

The arena is full. Try again in a minute.
