Build your squad from wave 1. Choose a slot below, then a role. Free between waves.
All five roles work at tier 1. Merge equal tiers: 1 + 1 → 2, then 2 + 2 → 3. The receiving robot keeps its role. MERGE ALL combines every matching tier in the barracks. Bosses resist control; matching effects refresh instead of stacking.
Merge Bastion: Robot Defense
Your army is holding position.
Drag matching units together to merge. Drag units onto glowing pads to deploy. The gate holds enemies briefly; tap a junction to change their route.
