I don't know yet. Depends what will be left to STOMP 2. Probably no big improvements for 1.2.

* Laptop Personnel info enhanced, that's for sure. (I'm working on it now.)
* Probably IMP e-mails (about your IMP characters) will be remade to fit the new system.
* Ranger's camo effectiveness bonus fixed (is deactivated now).
* Then some tweaks around, updates of code behaviour.
Maybe:
* AI able to throw grenades on "guess" (no need to see your mercs)
* AI able to throw greandes on roofs (related to above)
* Enemy Squadleaders can get special colour (externalized)
* Start New Game settings screen enhanced to contain much more options (new pages added maybe)
* Possibility to ambush the enemy squad (same way as they can)

But don't get too excited, I am unsure, what I'll be able to actually make.
