One Server - On a MASSIVE Scale

WWII Online is a massive scale WAR going on 24/7 driven by players. There are absolutely no zones, you can fly your aircraft from one end of the map to the other without despawning.

Hundreds of players can end up in the same fight or supporting that battle in the Army, Air Force or Navy.

This scale and combined arms realism is the core that makes WWII Online stand out from everything else on the market.


More about WWII Online

All combat is alongside live players in the same zone-less 300,000 sq km game world where every vehicle or weapon is controlled by a real person.

You have the option to either join existing squads or create a new one with your friends. Create your own command structure and plan how you will conquer the enemy.

Do you have exceptional leadership qualities? Lead your side to victory as a High Command officer. Move forces to attack objectives or defend your territory.

Physics Based PVP Combat

Combat Realism

Realism is taken to a new level - This isn't another arcade-style WWII shooter! Our weapons and vehicles are modeled utilizing historical data after hundreds of hours of research.

The game's designers came to WWII Online from award-winning MMO combat flight simulation titles and have carried over a dedication to realism and simulation style game play whenever possible.


A proprietary physics engine powers an advanced, component-based damage model for vehicles that simulates the actual components found in WWII units. In addition, we accurately model armor thickness down to the millimeter and flight models for aircraft down to every surface and control for a true-to-life simulation. Even the ballistics are precisely and accurately modeled for each type of bullet or round in the game.

All of these elements provide realism, creating a skill-based simulation where players must learn to properly employ the weapons and equipment available.

The video seen below helps explain damage and ballistics modeling in the game and gives you a taste of the simulation style gaming experience in WWII Online.

Damage Model Explained

The below video was created with a previous version of the game's graphics engine and does not represent the current graphical presentation.

Real Players - Real Time

Massively Multiplayer (MMO)

All combat is alongside live players in the same game world where every vehicle or weapon is controlled by a real person. The game world is a single zone-less map set at half scale of the European Theater between 1939-1944. From this map, the game provides winnable campaigns that are completely player-controlled and non-scripted. Some campaigns have lasted for more than two months before a victor was decided.


We believe that, more than in any other MMO game, effective teamwork is a requirement for victory in WWII Online. Click a button below to learn more about an area of interest.

Allied Forces VS German Forces
