A fresh city layout is generated whenever the page loads. Buildings are arranged into clean city blocks, and houses around the neighbourhood will light up when they place an order. Pick up a pizza from the shop, deliver it to the highlighted house, then return to the shop for the next pizza.
Unfortunately the neighbourhood is full of extremely slow zombies, and ordinary traffic is still trying to get around the city. NPC cars can hit zombies — and they can hit you too. They wander aimlessly until you get close enough for them to notice you.
WASD or Arrows to drive, Space for the handbrake. Hit zombies fast enough to kill them, but every impact damages the car. Use E at the mechanic for repairs and upgrades. Fuel also runs down as you drive; the gas station refills the tank for £5.
Simulation Mode runs the city autonomously. Use WASD or the arrow keys to move the camera and watch traffic, pedestrians and zombies interact.
