Undead Slayer

Play Undead Slayer With No Download

No installs, no launchers eating up your hard drive, just a browser tab and a horde of rotting bodies shuffling toward you. Undead Slayer drops you straight into the action the moment the page loads, and that instant-play feel really suits what this game is going for. It's built around short, punchy missions rather than one long slog, so you can knock out a level or two on a lunch break and still feel like you accomplished something.

Features

• 100 separate levels, each throwing a different objective at you instead of just "kill everything and move on."
• Mission variety that swings between guarding a hostage and holding a defensive line, which keeps the pacing from going stale.
• A weapon upgrade system, so the pistol you started with won't cut it once the later waves get nasty.
• Grenades and air strikes on standby for when the screen fills up faster than you can aim.
• A knife option for close-quarters panic moments when reloading just isn't going to happen in time.
• Straightforward WASD movement paired with dedicated keys for firing, weapon swaps, and special attacks.

Top Tips

• Don't blow your air strike the second things get hairy — save it for the moment a swarm actually surrounds you.
• Upgrade your weapon before you assume you're just bad at aiming; a weak gun makes early levels feel way harder than they should.
• Switch weapons with Q on the fly rather than sticking to one gun the whole match, since some missions clearly favor range over spread.
• Keep the knife (L) in your back pocket for when a zombie gets uncomfortably close and your clip is empty.
• When you're defending a hostage, position yourself so you're not just shooting outward blindly — check your flanks, because they will come from behind.
• Grenades are great crowd control, but timing them a beat late, right as enemies bunch up, gets way more value than tossing one early out of nerves.
