''Strania -The Stella Machina-'' is a VerticalScrollingShooter by G.rev, the same developers behind ''VideoGame/BorderDown'' and ''VideoGame/SenkoNoRonde'', as well as the providers of the engine used in Creator/{{Treasure}}'s ''VideoGame/{{Ikaruga}}''. ''Strania'' is an old-school throwback to classic arcade shooters of the 1980s.

The arcade game was first released in 2009, players take the role of the Stranian force's Soichirou Touma (player 1) and Yu Beatrix Barrett (player 2) as they pilot their {{mecha}} and take on the Vower. Just as the old shoot 'em up days, players plows through everything that stands in their way, collecting various weapon {{power|Up}}-ups, and generally [[StuffBlowingUp blowing stuff up]].

It was later released for the Xbox 360 via UsefulNotes/XboxLiveArcade on March 30, 2011. Roughly two months after its release, G.rev released the [[DownloadableContent downloadable]] ''Side: Vower'' ExpansionPack for the game. As the title suggests, the ''Side: Vower'' expansion allows the players to play as the enemy forces, the Vower's Yosemite (player 1) and Su Quadra (player 2), while the game's original stages are played in reverse, adding in a new soundtrack, and throwing in a [[HarderThanHard harder]] game. A PC version has since been released in Fall of 2015 through UsefulNotes/{{Steam}}.
