Endless Undead is a fast lane-defense survival shooter where you move your army left and right while your troops auto-fire into relentless zombie waves. Build a run with smart timing and positioning, survive escalating elites and bosses, and spend Zombie Bucks mid-run in the Zombie Killer Shop for clutch upgrades, consumables, and structures. Between runs, invest earned run tokens into permanent upgrades and weapon progression to push farther each attempt. Every run is about momentum, adaptation, and seeing how long your strategy can hold. Controls: Move with the arrow keys or mouse, throw consumables with W / A / D, place structures with 1 / 2, open the in-run Zombie Killer Shop between waves, and press ESC to pause. Suggested age rating: Teen (13+). Contains stylized zombie combat (gunfire, explosions, cartoon zombies and bosses). No realistic gore, no strong language, no sexual content. AI disclosure: AI tools were used during development to help generate art assets (zombie sprite sheets, weapon and upgrade icons, environment textures) and to assist with code authoring. All assets and code were reviewed, edited, and finalized by the developer.
