The ultimate combat simulation from the developers of Operation Flashpoint

In ArmA: Combat Operations, players engage in the story- driven single-player campaign or take part in huge multiplayer battles with more than 50 players on one battlefield at once. Featuring a vast environment with more than 150 square miles to explore, ArmA: Combat Operations allows players to pilot or drive more than 30 vehicles including APCs, tanks, self- propelled anti-aircraft guns, helicopters and fighter planes. The game features an extremely powerful built-in editor which allows players to create and share complex missions as well as import user-created units and maps.

It offers the ultimate realistic combat simulation experience in a modern day setting. With unique freedom of movement, actions and tactics, the game takes immersive strategic battles to a whole new level.

A small US Army contingent has been sent to the Atlantic island of Sahrani with the purpose of helping to train the army of the local pro-American monarchy. The Kingdom of South Sahrani, rich in natural resources, has always been at odds with its Northern neighbor, the Democratic Republic of Sahrani. In recent years however, the situation has settled into an uneasy yet peaceful coexistence.

But the Democratic Republic of Sahrani sees the training of Southern troops by the US as a threat. When they learn that the US troops have finished their deployment and are in the process of shipping out, the North prepares to strike while a false sense of security still occupies the minds of their Southern neighbors.
