Apparently the pack will include new weapons (sniper rifles!), grenade launchers, and glow sticks have all been added. From community members who've read the article, it appears changes that were often requested have now been implemented.

In a surprise move, IG Boston isn't working on the expansion pack, but instead IG Australia, their counterparts in the southern hemisphere. VUG hasn't announced the game formally, but said that such an announcement isn't too far off.

- Compliant, but unsecured suspects can no longer be considered secured. They will have to be secured, as was the case in SWAT 3.
- The expansion pack promises to offer missions which will be tied together by a linked storyline (a suspect is on the run across multiple missions).
- Simultaneous commands to both the red and blue teams is possible.
- Co-op missions for 10 players will now be supported.
- The quick mission maker can create scenarios which can be used in co-op.
- Voice-issued commands will now be more crucial.
- Suspects will now use blind supression fire.
- Evidence at a crime scene can be disposed of by suspects.
- A new multiplayer mode is planned which will feature "asymmetric" weapon distribution (think of Splinter Cell's multiplayer modes, perhaps?).
