Show HN: Roadkill – a zombie car game inspired by the original GTA's driving

Roadkill is a top-down zombie car game that blends old-school GTA-style driving with arcade survival. Players drive through waves of zombies, running them down to collect scrap, chaining kills into combos for bigger scores, and repairing armor between waves. Scrap functions as currency to upgrade the car and three self-aiming guns; upgrades persist for that run and are chosen in a buy screen before the next wave. The game emphasizes drifting and rear slides to maintain control at high speed, and awards and new vehicles appear as milestones for long runs.

Single-player and two-player online modes share the same city and wave progression but keep scrap and purchases separate; multiplayer is anonymous and color-coded with no chat. Controls work on touch (a left-stick throttle/steer and a right-side drift button) and on keyboard (WASD/arrows to drive/steer, Space for handbrake/drift), with standard pause and sound toggles. Leaderboards include weekly and all-time high scores, and a simple Type Dojo-based account system (username/password, no email) lets players save cars and runs across devices. Gameplay draws inspiration from Pat Kerr’s Motion Lab and classic GTA driving mechanics.
