About
Store description and overview from Steam.
What you do during the day pays off at night: gather resources, place buildings, merge structures, trade resources, choose your NPCs wisely, send them on expeditions, deploy soldiers, merge units, and position your troops strategically.
Factory Buildings: Produce the main resource you need to build and upgrade your base.
Ammunition Buildings: Create ammo for soldiers, defenses, and special attacks.
Barracks Buildings: Train new soldiers every cycle.
Laboratory Buildings: Generate research points for permanent upgrades that carry over between runs.
House Buildings: Increase population limit, allowing you to grow your army.
Merge-Based Building System: Soldiers and buildings automatically merge when placed smartly on the grid.
When night falls, don’t give up if your strategy isn’t working. You still have tricks: call in airstrikes and collect boosters to power up the defense units you placed during the day.
Lost a run? It’s time to come back stronger. Spend the research points you’ve earned, pick the permanent upgrades that match your strategy, and try again. Each run, you’ll get better than the last.
Permanent Meta Progression: 13 research trees providing persistent upgrades.
13 Research Trees: Choose upgrade paths trough 150+ meta upgrades that complement your playstyle.
Constant combat, constant adrenaline! As you defend your city, the action never slows down for a second. Build your strategy and stay in control in the heart of the battle.
