Game Editors

Here is a list of some 3rd party software that can be used to manipulate UFO:Enemy Unknown. (Apologies if there is already a list elsewhere on the site, but I tried to find it and did not succeed.)

XcomUtil can perform various changes to the game. Some changes are relatively easy using the xcomutil.bat script. Others are harder and require you to edit text configuration files. Clunky, old skool, but very powerful.

XcomUtil also includes a utility called SDump. This is a hex dumper / patcher that is configured for XCom. Very technical and old skool but very powerful. Use with care and read the manual first. Probably only usable by old skool programmers.

ClarkWehr editor. This is a soldier and base editor for XCOM and TFTD. Reportedly has some bugs. It has a GUI but it is character-mode DOS type of GUI. Also has command line switches so you can run it in batch mode. Lots of features.

XCOMHack and other tools by Chris Voss (Hatfarm). XComHack is a VB program that can edit soldiers, bases, craft, diplomacy and global factors such as money. Pretty much everything that ClarkWehyr can do and easy to use. It is a Visual Basic Forms application and the source code is available to extend. That's a pretty good deal. There are also some more powerful utilities available here to patch the executable and similar zany things.

UE Matt Mullen's UE editor, just for editing bases and money. A very simple DOS character mode "GUI". This also comes with source code and is written (nicely) in C. Nice.
