Latest Muv-Luv game is multi-platform, with Mobile, PC and console. A video from the beta.
If you are not familiar what the MUV-LUV universe is, here is a short primer. For thirty years, it had a series of light novels, games, manga and anime series under its belt, with the latest one slated for October 2021. The creator of Attack on Titan admits partial inspiration from this franchise.
To sum it up, humanity is desperately fighting for its very survival against an alien invasion of monsters using mecha. No shortage of blood and gore, main characters getting killed right and left, echii you heard it right, and waifu here. If you are thinking Gundam or Armored Core fighting the Zerg, that's the general idea.
