I finally tried this out, it's a fairly simplified X-Com clone. Geoscape has no base-building, just soldier/equipment management (kinda like early UFO:AI) and research, and battlescape missions pop up overtime.
Battlescape is pretty much the same, you move around your dudes in turn-based fashion until you shoot up all the aliens, with destructable terrain, lighting, TUs, shot types, etc. No complex inventory management.
Interface works well on mobile, though a bit tiny on my phone. There's also some sort of plot but I couldn't really care since the english is really crude.
