Phoenix Point's Terror from the Void mod is so good Snapshot Games just released a massive patch to make the original game more like the fanmade overhaul

What a strange history Phoenix Point has. At the height of X-COM mania, when Firaxis was riding high on its subversive sequel to its 2012 reboot, the series' original creator Julian Gollop revealed his own spiritual successor to his massively influential game. Phoenix Point aimed to reimplement much of the granularity that Firaxis' slicker overhauls took out, adding features like soldier inventories, multiple human factions, manual aiming, and mutating enemies.

Phoenix Point seemed to have the makings of a stone cold classic.
