From the article, "Steam user Pluvia made my night last night. That’s when I discovered the existence of Mass Effect Civilization V mods. Yes, Pluvia got Mass Effect into my Gods & Kings updated version of Civilization V, and I couldn’t be happier. In fact, I’m ecstatic. Ebullient, even. Thank you so, so much!
Here’s how it works. Go on Steam, if you have Civilization V and the Gods & Kings expansion. Check out the Steam Workship: Mass Effect Collection."
