10 Awesome Multiplayer Video Games Nobody Played
3. Shattered Horizon

Shattered Horizon was nothing if not a bold attempt to do something totally different with the FPS, for while it launched with an undeniably scant package - namely no single-player mode - at its core it was one of the most unique multiplayer shooters on the market.
From the sadly now-defunct outfit Futuremark, Shattered Horizon saw players thrown into team-based, zero-gravity space shootouts, and as terrific as the core shooting mechanics and graphics were, many took umbrage with its undeniably steep learning curve.
On launch there were no bots to help players get acquainted with the game's eccentric locomotion - it being space and all - and so many simply failed to invest sufficient time to get used to laying down fire in space.
Basically, this wasn't just Call of Duty in space several years before Call of Duty itself actually went to space.
Between the patience required to "git gud," the small amount of content available on launch, and the game requiring DirectX 10 several years before most AAA games themselves did, Shattered Horizon's time in the spotlight was unsurprisingly short-lived.
After Futuremark stopped supporting the game in 2014, they had it removed from Steam. Gutting.
