Microsoft Allegiance is a multiplayer space combat simulation game developed by Microsoft Game Studios. It offers ship-to-ship combat action, where players fly and man turrets of small, agile scouts to massive destroyers. The game has real-time strategy components such as tech upgrades and massive multiplayer capability. It stands at the forefront of online interstellar combat.

The game offers everything one would expect from an RTS, including tech trees, exploration, and base building. However, all units, except miners and base constructors, are flown by real players. Each team has a commander who manages the team utilizing the overhead command view. The commander is usually a veteran with extensive knowledge of the game's factions, economy, and strategies.

Allegiance provides a unique gameplay experience with a higher learning curve, but it is extremely rewarding. The game starts with most of the map undiscovered, and players must wipe out their enemies' bases. Maps are divided into several sectors, and players must escort a constructor in one direction while others scout out the rest of the map and set up early warning sensors. The economy is key in Allegiance, so defending your miners and making sure your base constructors reach their targets is essential.
