Steam says it requires the base game of XCOM EU for it to play.... but does it give any continuity from that game at all? ie, are your guys from XCOM EU accessible and do they keep their stats/levels in XCOM EW?

Thanks!

It is an enhancement of the original campaign.

I know, but how much of your "original campaign game save" does it use? Do you get to keep your guys and do they keep their skills? Or do you start from scratch? Are you still limited to one base or can you build more? Do you keep your old base or do you start from scratch?

My understanding is that the game can be played in Original mode or with the Add-On content. I would presume a save created in the original game would work in Original mode only, but it would be a pleasant surprise if someone were to correct me on that.
