This multi-platform engine was built from scratch to provide a bug-free and greatly enhanced version of this classic game. It's super mega big awesome.

An original copy of Xcom is required as it uses the original assets. Sadly, it's not on GOG, but it's on Steam, GamersGate, Amazon and probably others...

Search is friend :)
There is already one OpenXcom v1.0 -thread over here, bit buried over already. :)

Will this work with the original 3.5 discs of XCom? Is it a graphical overhaul or what? Thanks!

OpenXcom just reads the files and reinterprets the data. This means that various things like opening doors easily, tool-tips, new gameplay options, fixes, and so forth are allowed by OpenXcom. No new graphics, unless you use mods.

Damn it! I already did a search and it showed up nothing. Is this the price I have to pay for using DuckDuckGo instead of Google?

No, it's the price of shitty forum search functionality.

Hear hear.
