Block Zero

About the game

You start Block Zero standing on a roof with a crowd of infected below, and the only way forward is down. The city runs from calm housing blocks through a quarantine zone to the offices at its northern end. Walls are stairs, rooftops are runways, and nothing stops you from crossing the whole map without a loading pause.

Terminals hand out short jobs: thin out the infected, find a witness, torch a nest that sends three waves back at you. Between jobs, glowing yellow pillars offer timed medal runs, and failing one costs a single key press. Hurt an enemy enough, absorb it, and you heal and even wear its face so guards leave you alone. Each day brings one shared challenge with a strange twist.

How to play

• Move with WASD or the arrow keys, hold Shift to sprint, and run straight into a wall to scale it. Tap Space to jump, hold it for height, keep holding mid-air to glide, and hit Ctrl to dash.
• Left click slashes. Three clicks make a combo. When an enemy is marked as weakened, press E to absorb it.
• Press E at a terminal or yellow pillar to begin. Q shows targets through walls, R restarts a challenge, Esc pauses.
