Shamble Siege: Zombie Shooter – Play Free Online

About Shamble Siege

New

Shamble Siege is a free zombie shooter you can play online in your browser, with no download needed. Zombies are everywhere. Pick one of seven heroes and fight through endless stages built fresh every time: downtown streets, an old village, deep jungle, dusty desert, a frozen pass and lava fields, by day and by night.

Every stage has a mission: defeat the horde, survive, find supply crates, switch on radio beacons and reach the chopper, defend the generator, or topple a giant boss every fifth stage. Twelve kinds of zombies include runners, crawlers, brutes, acid spitters, bombers and screamers.

You start with the trusty Pea Blaster. Defeated zombies drop SMGs, shotguns, rail rifles, flame hoses and rocket tubes, plus bombs. The cartoon style keeps it fun rather than gory. It plays on phones, tablets and computers. Shamble Siege is an original game made by the GamesYap team. For space battles, try Nova Strike.

FAQ

Is Shamble Siege free to play?

Yes. Shamble Siege is free to play in your web browser, with nothing to download or install. Coins dropped by zombies and found in gift boxes buy heroes, outfits, starter guns and upgrades in the Shop.

Can I play Shamble Siege on my phone?

Yes. Shamble Siege is built for one-thumb play on phones. Drag anywhere to walk, and your hero fires automatically. Buttons handle bombs and gun swaps. It also plays on tablets and on computers with WASD and the mouse.

Is Shamble Siege too scary for kids?

Shamble Siege uses bright cartoon art, silly zombies and bosses with names like Big Grumbles, and no realistic gore. It is still a shooting game with lots of action, so parents may want to try it first before younger children play.

How do lives work?

You have five lives, and they refill over time. Each stage costs one life, and winning the stage gives it back. Inside a stage you have 20 health, so play carefully to keep your lives for longer sessions.

Who are the bosses?

A giant boss appears every fifth stage: Big Grumbles, the Hive Queen and the Inferno King. Boss stages also have a zombie counter. Defeat the horde and the boss to clear the stage and earn the Boss Basher achievement.

What's new

Version 2.5.10Nov 2, 2026

Menus, shops and result screens: rows of cards and boxes never leave one alone on a row (balanced or centred) on every screen size.

Earlier versions

2.5.9Result screens: the score boxes always sit in even rows (never one box alone on a row) on phones, tablets and computers.
2.5.8No more stuck stages: zombies walk round cars and buildings instead of pushing into them, and the last zombies of a stage always come out where your hero can shoot them. A lost ad-break answer can no longer leave an empty screen between stages. Achievement notes show their names.
2.5.7Smoother on phones: lighter drawing every frame, less stutter.
2.5.6Runs smoother on phones: no more sudden freezes, less stutter, and touches are never lost. The points icon now shows where your points go.
2.5.5Store art: the game title on the covers no longer hides under the NEW badge.
2.5.4Clearer wording: ad rewards give coins only (never points), daily chests show their prize chances, and a few names were made original.
2.5.3Sharper graphics on phones: the game no longer drops to a low-resolution canvas on slower devices.
2.5.2The zombie counter sits in the top row next to coins and score; busy moments (screamers, horde rushes, pickups) are short notes at the bottom, one at a time, so nothing covers the action.
2.5.1The results card explains GamesYap points: each stage pays once a day (replays still give score and coins); signed-out players are told to sign in.
2.5.0Stage 1 has exactly 50 zombies to defeat (all of them), each stage 20 more up to 500; the last few come to you. An easier start that gets harder step by step, and many more bullets per gun. Every zombie pops with its own funny sound (bosses get a sad trombone). After a win the hero dances with confetti before the results (stars, points, coins). In-game notes are small and low, so nothing covers the action.
2.4.0New daily chest: one free chest a day and a few more for ads (coins only). The menu and the pause screen show what your GamesYap points are worth where the platform can send them, with a button that opens the platform's own send dialog.
2.3.0Every stage is now clear: a big counter at the top shows how many zombies to defeat (boss stages: then the boss), with Horde Rush waves on the way; tougher zombies and stages. Hold the bomb button and drag to aim (a red target shows where it lands). The gun button shows the gun in your hands with a glowing ring of bullets left. Gift cards explain each gift; active boosts show their seconds; a gift guide in the pause menu. Zombies cannot cross lava (they use the bridges) and burn if pushed in; mud slows them. Buildings and trees in front of you fade; a ring marks your hero; zombies topple over; ground grain, sunlight, clearer coins on snow. New: daily reward (7 days), three daily quests and free coins for an ad. Points unchanged. 2.2.0 and earlier — Bullets per gun and gun drops, a shop for coins or ads, the hero showcase menu and new covers (2.2); one-thumb auto-fire, coin and gift loot, laid-out stages (2.1); seven heroes, generated stages, missions, bosses and lives (2.0); 1.x waves in the park.
