Greeb is coming for the Grid, and you are the firewall. Blast waves of cyber-threats out of the sky, draft upgrades between cycles, out-hack the boss in a rhythm duel, and hold the line as long as you can. Endless score-attack arcade defense with four difficulties and 42 achievements.
Play as Harold, an office worker in his 60s recruited to fly drones for his government. His missions decide whether an AI surveillance programme ends crime in the city, or whether he shuts it down.
