An anonymous office skyscraper in the city. A rogue email containing a deadly brain-melting cybervirus. One minute you're buried in spreadsheets and the next you're fighting your way through the undead. Now you and your co-workers must make a break for the roof and a helicopter evac - survive at any cost!
Press and hold the mouse button near survivors to move them - move the mouse with the button held down.
Arrow keys or WASD will scroll the view around.
Space will toggle the map view.
CTRL and mouse click can pick out a single survivor to control instead of the whole group.
