For XCOM: Distilled, you can try Alien Star Menace. What's left of the xcom mechanics are squad configuration, 2-action turn and a few weapon types behaviours (e.g. shotguns works like in xcom). I wish it has researching, but the game compensates it with different unit types that you acquire from playing the game normally. There's no f2p p2w shenanigans.

The art style actually comes from this game, so I think it's just being used as a placeholder for now
Alien Star Menace has me pretty hooked right, its a cute turn based strategy game.
