Can anyone else remember a mobile game where it revolved around you. An allied soldier or robot being sent to infiltrate a military base/ research center owned by a Nazi remnant after WW2. Who happens to be a scientist. The base itself is located in some kind of arctic/antarctic hyperborea. As for the game itself, it was somewhat challenging. With each level being a bullet hell facing some kind of giant animal/robot/cyborg which wanted to kill you. Had roughly three lives and each time you were hit you lost one. Though you could increase this number iirc.
