OpenXcom “From the Apocalypse”

Most likely, not everyone knows that there is such a mod for OpenXcom “From the Apocalypse 0.12.0” in which a mind-boggling amount of everything from Apoc is transferred and, at the same time, very high quality and professional, and I think such work is worthy of mention and all praise.

X-COM 3: Apocalypse is still the best.

The X-COM 3: Apocalypse concept was much more ambitious than the first two games. The ideas conceived by Julian and Nick Gollop were so far ahead of their time. However, only a small part of their concept was realized. Our goal at OpenApoc is to implement this grand, original idea and more.
