About Metal Slug (Series)
SNK's legendary run-and-gun arcade series with hand-drawn pixel art and tanks.
Metal Slug began in 1996 on the Neo Geo arcade system. Soldiers Marco, Tarma, Eri and Fio blast through richly animated levels, rescue prisoners and hijack vehicles such as the Metal Slug tank.
This page covers browser-playable entries of the series; two-player co-op is a classic way to play.

How to play Metal Slug (Series) in your browser
- Press Play in browser — the game opens on wasmarcade.com in a new tab.
- Wait while the game files load. The first start can take from a few seconds to a few minutes depending on your connection; later starts are faster because the browser caches the files.
- Click inside the game window so it captures the keyboard and mouse, then switch to fullscreen (F11 or the host's fullscreen button).
- Open the in-game settings to adjust controls, graphics and sound. Progress is normally kept in your browser storage, so don't clear site data if you want to keep your saves.

What to expect from the browser version
The browser version of Metal Slug (Series) is an independent web project — a port, recompilation or fan remake — hosted on wasmarcade.com. It is not an official release from SNK, and MePlayable does not host any game files: we describe the game and link to the project.
Because the game runs inside a browser tab, some features of the 1996 original may be missing or work differently: online modes, cutscenes, saves, mods and graphics options depend on the build. If something doesn't work, check the host's own notes.
Requirements
A modern desktop browser — Chrome, Edge, Firefox, Opera or Safari 16+ — with WebAssembly and WebGL enabled, at least 4 GB of RAM and a stable connection for the first load. Hardware acceleration should be switched on in the browser settings.
If Metal Slug (Series) doesn't start
- Black screen or endless loading — update the browser, enable hardware acceleration and reload the page with Ctrl+F5.
- No sound — click inside the game window: browsers only allow audio after you interact with the page.
- Lag or low FPS — close other heavy tabs and programs, then lower the resolution or graphics settings in the game.
- The site doesn't open — the host may be temporarily down or blocked in your region. Try again later or use another project link on this page.

Can I play Metal Slug (Series) online for free?
Yes. The browser version on wasmarcade.com is free to open, and MePlayable doesn't charge anything — we simply link to the project.
Do I need to download Metal Slug (Series)?

The browser version is made for computers and expects a keyboard and mouse or a gamepad. Some phones and tablets can open it, but performance and touch controls are not guaranteed.

The original game had multiplayer, but online play in the browser depends on the build: some versions are single-player or local only. Check the host's menu for online options.
Is this the official Metal Slug (Series)?
No. The original Metal Slug (Series) was developed by Nazca / SNK and released in 1996. The browser version is a third-party project, and all rights to the game belong to their owners.
Will my progress be saved?
Usually yes: saves are stored in your browser's local storage on this device. They are lost if you clear browser data, use private mode or switch to another browser or device.
