Enemy machines are closing in on Neo-grad, and only your team of combat drones stands between them and the city's last line of energy defence. Deploy your drones to the open platforms, merge identical models of the same rank to create powerful combinations right in the heat of battle.
The enemies fight back: silencers jam your drones, bombers strike the area, shield carriers protect their squad, and support units repair their allies. Bosses unleash EMP attacks, launch rocket barrages, and call for reinforcements. Monitor the strength of your platforms and adjust your formation before the enemy hits.
Each wave brings new tactical opportunities: you can speed up your squad, repair drones, raise barriers, freeze the enemy advance, or turn plasma charges into supernovas. Clear 24 sectors across six districts, destroy command vehicles, unlock four drone models, and upgrade your lab.
Enjoy the endless "Night Watch" mode, daily missions, achievements, a series of entries, and offline rewards. Your progress is saved automatically.
How to play
To begin the fight, press "Defend Sector". The drones will fire automatically. To deploy a drone, hit the designated button and choose an available platform highlighted on the screen — this is when the battle energy surges. Combine two identical drones of the same level by tapping on them or dragging one over the other to create a more powerful model. You can convert an unwanted drone into energy using the "Scrap" button.
After every wave, pick one of the three enhancements. The green bar under the drone indicates its durability; replace any destroyed drones promptly. Watch out for the boss' warnings and protect the core on the left from the enemies. In between battles, purchase permanent upgrades in the lab.
Controls: on a computer, use the mouse to select, move, and merge; spacebar to pause; and the number 2 key to adjust the speed. On a mobile device, touch and drag; play in landscape mode.
