Aside from being an isometric tactical strategy with destructible environment, XCOM Ufo Defense is not as similar to Into The Breach.I_am_person wrote:I'm surprised that nobody mentioned x-com here. Of course right now with the fancy and advanced #2 having relatively recently come out, it might not associate as well, but for me personally the moment I saw the pictures the first thing that popped up into my mind was a map from XCOM-UFO Defense. Anyway, what I'm trying to say with my comparison is that I hope it'll be hard as what I just mentioned above.
As I've mentioned before, this game is more akin to Front Mission:

A tile-based isometric rpg/strategy.
