XWC

Used in the following game(s):

• Syndicate

Used in a few other games made by Starbreeze Studios. Multiplatform engine. Unknown on actual name. I've heard it called "Union Engine" but that was mostly on wikipedia and then sometimes just called "Starbreeze Engine" which means nothing.

Structure

Working on it..

Research

First 48 bytes is the header data, starting with a magic identifier. Many of the archive formats used in this game look the game but are slightly structured differently depending on extension. Using extension as a means of IDing a format is never a good idea so header needs to be completely reversed. At 0x18, This appears to be a file location. Maybe a starting point. It then has a small index but doesn't appear to be file entries but maybe data type entries. Looks like an interesting format.
