I've never played the X-Com games before, but I'm pretty sure this new game has no connection with that series from what little I know about both. This is a first person shooter set in the 1950's with some kind of paranormal theme. The other X-Com was an isometric view RPG/Strategy series that involved aliens and carried a futuristic sci-fi theme.
If, for some reason, this is actually supposed to have something to do with the other X-Com game series, then the developers have failed miserably in capturing anything even closely resembling it. If their goal was to do what Bethesda did in Fallout 3, then they've failed at that too, since Fallout 3 was still very much a Fallout game but with a different view and combat. There's nothing here that ties it to the other X-Com series, so if their expectation is that people will see this as somehow connected to it then they have failed at that as well. I can only assume that this developer liked the name "X-Com" and didn't realize it was taken.
