Zombie Attack: Defense

Can you hold the line when the dead pile up from both sides? Rifle, bombs, and a screen-clearing nuke are all that stand between you and the swarm.

You're one soldier with a rifle, a handful of bombs, and a nasty habit of getting cornered. Movement is simple: A and D walk, W or Space hops over the low crawlers, and your left mouse button does the talking. What makes it tick is how quickly the horde adapts—slow walkers in front, runners behind, and you're constantly backpedaling just to keep a gap. The first few waves feel almost too easy, then a crawler sneaks under your shots and suddenly you're jumping out of a corner with half your health gone. Right-click bombs are your real crowd control. The fuse takes a beat, so you have to throw where the pack will be, not where it is now. I wasted my first three bombs on empty ground before it clicked. The Z-key nuke is the panic button—drops everything on screen to ash and gives you a fresh line. I thought it was just a gimmick until wave 14, when six zombies hit the barricade at once and one nuke turned a loss into a second wind. There's no fancy upgrade tree or story, just escalating pressure that forces you to move smarter and use every tool at the right moment. It's the kind of brutal, repetitive defense game that eats an hour before you notice.

A, D key to Walk, W or Spacebar to Jump, Left mouse - shoot, Right mouse - bomb, Z - Nuke.

Keep moving backwards while firing—standing still is how you get surrounded. Throw bombs ahead of the pack, not directly at them, because the fuse takes a tick. Save the Z nuke for when three or more zombies reach your barricade. Use jumps to escape corners and reset your positioning. Funnel zombies into narrow gaps to make your rifle and bombs more efficient. Don't waste bombs on single walkers; a few rifle rounds handle them fine.
