ZOMBIE SURVIVAL / OPEN WORLD / VERSION 0.7

A world to survive in.

An original, free browser zombie survival game. Leave Morrow, follow the roads, scavenge buildings, drive cars, and find a place to stay. Explore solo, recruit survivors, or join a world hosted by a friend.

After the Sirens gameplay: a top-down survivor among houses, roads, cars, and undead in Morrow
Original procedural world and artwork · Early playable build

Scavenge, craft, and keep moving.

Search houses and businesses for food, water, medicine, tools, clothing, and weapons. The searchable catalogue contains 3,455 original items and 4,457 crafting and salvage recipes. Item entries explain acquisition paths; browsing the catalogue does not grant free supplies.

Hunger, thirst, stamina, fatigue, bleeding, infection, and equipment shape every decision. Craft at stations, improve skills, grow food, share settlement supplies, and put up simple defenses. Buildings have accessible upper floors, while doors, windows, and walls can be damaged.

A seeded world of towns and wilderness.

Travel through farms, forests, riverside settlements, suburbs, and industrial districts. Enter a world seed to reproduce the same starting landscape, or continue a saved run with changes intact. The game streams nearby regions and keeps a bounded record of visited places.

Drive, reverse, refuel, and repair after a collision. Survivors can trade, follow the player, work, and fight nearby threats. Raiders, undead, weather, and the day-night cycle make the roads less predictable. Choose Open world for free survival or Rescue mission for the original radio-repair scenario.

Play solo, or host a world with friends.

Singleplayer runs directly in your browser, with no installation or account. It autosaves every five seconds during play and on page exit. Continue restores the run; export and import keep a portable copy. A previous valid backup can recover a damaged primary save. Browser saves stay on this site in the same browser.

Multiplayer supports up to 20 connected players on a world server run by a player or a friend. Hosts can provide private invites or list a public world. Shared worlds include text chat and optional proximity voice. The website serves the game; multiplayer needs a running, reachable host. The initial server list is empty until real hosts are submitted.

Version 0.7 is an early playable release. Multiplayer currently shares one loaded region and the ground floor. Keyboard, mouse and touch controls are available, with top-down and first-person views. The source repository documents the current limits and hosting setup.

Read the multiplayer hosting guide

For a small online preview, the hosting guide includes a manual free Hugging Face Space setup. A reachable host is still required. Free preview hosts may sleep or reset their disk; keep world backups. Singleplayer saves in your browser stay separate.

How gameplay data is used.

This website uses Vercel Analytics to understand page visits. Optional gameplay milestones are disabled by default; the game’s title and pause menus show whether they are enabled. When enabled, they measure: starting or continuing a run, reaching one and five minutes of active play, changing view, choosing a guide language, and ending a run. Active play excludes paused menus, hidden tabs and AI play. Those counts would help us decide what to improve.

The optional milestones would include only the relevant game mode, difficulty, view, guide language or run outcome. Names, chat, private invites, world seeds and saved games are not included. Query strings and fragments are removed from game analytics URLs. Downloadable offline builds do not send these events. Browser blocking or unavailable analytics never prevents play.

Getting started.

Choose Enter the town, then Singleplayer. WASD or arrow keys move; the mouse aims. Press E to interact, I for the pack, crafting, and catalogue, J for the journal, and V to enter a nearby car. Escape pauses and opens audio and graphics settings. Press P to switch between top-down and first-person views. On a phone or tablet, move with the left thumb and aim or attack on the right side.

The quick guide offers English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Indonesian, Spanish and Brazilian Portuguese instructions. These translations cover the guide; the wider game text remains English. Choose automatic graphics quality to adjust presentation to your device, or pick a quality level yourself. Graphics settings do not change survival difficulty.

Prefer to watch first? AI play uses a small local adaptive steering controller and rule-based actions to guide a survivor. It runs in the browser without an external AI service. Manual movement or combat returns control to the player.
