Right now its looking like we'll have 20+ maps (I just released Delta Build for testing purposes...so some maps may be dropped, etc). I've also included minor add-ons such as a new font (actually its the HACX font :3 ), new graphics, a reloadable railgun via DECORATE, and some other things inbetween.
Here are some screenshots:

Here's the D/L link to IGPack Delta build: http://www.zshare.net/download/68252385e3885e/ (only works with the latest internal build of Skulltag, unfortunately)
Originally the map deadline was Feb. 1st, but then I realized today that the pack will only work with 97d (which is still being internally tested). So, the release date has been moved to the day or or later of 97d's full release. I've dropped a few maps and I may be dropping a couple more after Delta build. This means that if anyone here would like to contribute something to the project (maps, etc), please feel free to do so. Just contact me and we'll go from there

Comments are appreciated
