SIGMAX APK v1.1.0 (Sigma Battle Royale)

The description of SIGMAX APK v1.1.0 (Sigma Battle Royale)

SIGMAX APK is the Android build of a 50-player mobile battle royale from Studio Arm Private Limited, the same game plenty of people still search for as "Sigma APK". It plays in the popular drop-in survival-shooter style: land from a plane, grab loot, and fight to be the last one standing. Our editor installed and checked v1.1.0 before this page went live.

One thing to set straight up front. This is the original app shared as an APK, not a modded build, and it runs online. The file on this page is scanned for malware and installed on a real Android device by our editors before publishing, something we have done since 2018.

What is SIGMAX?

SIGMAX is an online survival shooter for up to 50 players in a single match. You jump out of a plane, pick where to drop, then scavenge for guns, armor and med kits while a safe zone keeps shrinking. The playable area closes in as concentric rings, pushing everyone tighter together until only one player or squad is left alive. It is built to run on mid-range phones, so a flagship device is not needed for a smooth round.

The pace is quick. Matches are short, the early scramble for loot matters, and holding the edge of the ring can win you fights other players walk straight into. If you have tried other battle-royale titles, the core loop will feel familiar.

Version, size and requirements

Check the package name before you install anything called Sigma or SIGMAX. The real one is com.studioarm.sigma, and a download that uses a different package is not this game.

Controls and game modes

Controls are the standard touch layout for a mobile shooter. A stick on the left handles movement, and the action buttons sit on the right, fire, aim, jump and crouch, with a quick reload close by. You can pick items up, swap weapons and heal on the move once you know where the buttons are.

There are two ways to play. The classic battle royale mode is the main draw, one big lobby, last player standing. There is also a 4v4 team mode called "Fight Out" for shorter squad matches when you want something faster than a full BR round.

Online play and ban risk

SIGMAX is an online game. Your matches and your progress run on the developer's servers, not on your phone, so you need an internet connection to play. That server setup also shapes what is and is not possible here. Third-party cheats or modified builds that promise an edge in an online battle royale are a bad bet: they get accounts flagged, kicked mid-match or banned outright, and they often do not work at all. The honest advice is to play the clean APK and rank up on your own. A "mod" for a server-side shooter like this one is unreliable by design, so we do not host one.

Sigma vs SIGMAX — naming

If you have seen both "Sigma" and "SIGMAX", they are the same product. The game launched on Google Play as Sigma (also shown as "Sigma Games"), then the listing was renamed to SIGMAX. Same developer, same com.studioarm.sigma package, same battle royale. The two names just cause confusion when you search.

How to download and install

The download is a single APK, around 230 MB, and it installs like any sideloaded app.

1. Tap the green Download APK button at the top of this page, the file downloads directly, no registration.
2. Allow installation from unknown sources for your browser or file manager (Settings → Security).
3. If you already have a conflicting version installed, remove it first so the new file installs cleanly.
4. Scan the file, confirm the package reads com.studioarm.sigma, then open it, tap Install, and launch the game.

You will need Android 4.1 or newer and enough free storage for the 230 MB app. First time sideloading? Our APK install guide walks through the same steps with screenshots.

That is the whole card. SIGMAX is a straightforward online battle royale for mid-range Android, and the safest way to enjoy it is the clean file from a source you trust. Want more in the same lane? Browse the rest of our action games catalog.
