A city office has become host to a zombie outbreak! You and your co-workers must fight your way through 15 levels of corporate cadavers to reach the helicopter evac on the roof.
Press-and-hold mouse button to make any nearby survivors move towards the pointer. Move the mouse (still pressing the button) to navigate through the levels.
Arrow keys or WASD to scroll the level.
SPACE to toggle map view.
CTRL with mouse button press will select only one person instead of everyone nearby.
