Build date

  • Disc label: 1/09/2008
  • XEX: Sun Aug 31 22:41:02 2008
  • Dev Menu: Revision 6005 Mon Apr 21 06:50:59 2008.

All three of these dates are different, which makes it hard to determine the actual build date. The Dev Menu date appears to be a Subversion timestamp, so that could be the date of the actual code; the XEX date would then be when the game was actually compiled. The disc label date is one day after the XEX, so that would be when it was actually burned to disc.

  • There's an early version of Savannah Citadel Day in the files. It doesn't have any geometry or textures, but the collision and the object layout is present. It is very similar to the version of the level showcased in a trailer[1].
