Zombie Killer Game

Zombie Killer is a lane-based defense shooter: zombies shuffle in from the right side of the screen along three parallel rows, and you have to keep every one of them from reaching the left edge. Losing isn't about running out of lives — a single zombie slipping past your line is enough to end the run.

A session is a steady climb in pressure. Early waves are thin enough to hold with one gun, but as more zombies pile into a lane at once you're constantly switching rows, swapping weapons, and deciding when it's worth burning your helicopter support to clear a jam before it reaches you. Coins earned from kills go straight into upgrading your guns, your defenses, and that air support, so each finished level buys you a little more room to survive the next one.

Controls

• Up / Down arrow keys — move between the three lanes
• A — shoot
• S — call in helicopter support
• 1, 2, 3 — switch between your unlocked guns

On touchscreens, on-screen buttons replace the keyboard: lane movement sits in the lower left, gun switching in the bottom center, and shooting plus helicopter support in the bottom right.

Tips

• Don't spend every coin on your gun — a few points into your defense upgrades means one missed shot doesn't end the run.
• Save helicopter support for when two or three lanes fill up at once rather than using it the moment it's available.
• Switch guns proactively before a lane gets overwhelmed, not after — swapping mid-swarm costs you shots you don't have time to spare.

It's a good fit for short, replayable sessions — quick to learn, with enough upgrade decisions to keep later waves from feeling repetitive.
