Phantis

Phantis (Game Over II outside of Spain) is a multi-genre game that features side-scrolling shooter, beat-em-up, and platforming sections. In it, you control space hero Commander Serena, who has to infiltrate a hostile alien world to rescue her... companion.

The game was originally released in Spain as an original IP, but got re-branded by publisher Electronic Arts in the rest of Europe as Game Over II. Along with the name change, the game got a male protagonist, and a different story to connect it with events of Game Over.
