Imperium Galactic War (abbreviated IGW)^[1] is a massively multiplayer online real-time strategy game by Vavel Games, originally developed and published by Kabam in 2013.^[2][3] The game runs on a freemium model, and is supported through the use of microtransactions.

The premise of the game is simple; players begin by picking which faction they would like to be a part of. There are three factions. The Tyrannar Empire, The Sovereignty, and The Intergalactic Alliance. Whichever decision the player makes, will ultimately effect the way the rest of their game-play looks, feels, and functions. Each player has their own starbase, and fleets they have to upgrade in order to defend themselves from other players, or even attack other players and non-player characters (NPCs). Players can earn experience points and level up by upgrading their fleets and starbase, completing game missions, and engaging in live combat with other players and NPCs.
