About Ctrl+Alt+Defeat Zero Humanity

Ctrl+Alt+Defeat Zero Humanity is a 2D roguelike survivor game set in a world where robots have seized power, governments have fallen and leaders have fled. You play as one of eight resistance robots, fight waves of enemies, collect XP and build a loadout as you level up. Defeat each region’s boss to advance across the world map.

The resistance

The resistance includes unlikely human leaders: a surfer running operations between waves, a cowboy who never misses a shot, a hacker who erased his own existence and a chief who smashed a drone with a war club. You face human leaders resisting the machines in their own ways, from the Surfer Prime Minister of Oceania and the Presidential Cowboy of America to the Melancholic Chief of Brazil and the President in the Antarctic bunker.

Operators

Choose from eight resistance robots, each with unique stats, a starting weapon and a distinct visual identity:

  • UNIT-7 “Iron Wreck”: tough and reliable.
  • NEXUS-3 “Hacker”: fast and unpredictable.
  • ARACHNO-X “Spider”: the fastest unit on the field.
  • ORBOT “Drone”: built for range and mobility.
  • SENTI-9 “Sentinel”: has maximum armor.
  • ROVER-D2 “Dusty”: collects everything and keeps moving.
  • AMAZÔN-IA “Hard Shell”: has heavy shielding but moves slowly.
  • QUAD-K9 “Sniffer”: tracks and eliminates threats.

Regions and bosses

Travel through nine regions, each with its own boss and themed enemies. Every region also has a 20-second special event that changes the fight: bureaucracy zones drain XP, the Moon has chaotic gravity, and the Brazilian rainforest brings wild thorns. Regions hide secrets, some of which only become apparent if you pay attention.

Weapons and upgrades

At each level up, choose from active weapons, passive items and rare evolutions. Items come in common, rare and ultra-rare tiers, including Overclock Ultra, which unleashes a 360° blast. The Luck passive improves your odds and draws more valuable special enemies into a run.

Special enemies that can appear during runs include the Hacker, who sabotages everything; the Crazy Priest, who exorcises robots with holy water; the Shady Banker, who invoices you for every defeat; the Quantum Coach, who rallies armies of bare hands against steel; and MECHA-H1 “Last Argument,” a colossus that does not distinguish friend from foe.

Infinite Mode

Conquering Antarctica unlocks Infinite Mode. It brings endless waves, random bosses every 10 cycles and difficulty that keeps increasing without a ceiling. The wave counter is displayed as Wave X/INF.
