Who wants to read a Destructoid review from 2011? Strania - The Stella Machina has come to Steam today apropos of nothing (the product page notes it's developer G.rev's "long-awaited debut on Steam," by whom I do not know).
G.rev is made up of former Taito (Space Invaders) employees that worked on shooters like G-Darius and RayStorm. The company got by first with contract work, assisting Treasure on the development of Gradius V and Ikaruga. Square Enix bought Taito in 2005. G.rev's last western release was 2013's Kokuga on 3DS.
Strania on Steam comes with the "Side Vower" DLC that let's you, "play as a pilot in the Vower camp that seeks to reclaim the land they hold sacred."
