SEGA announced that a new patch for the PC version of Rebellion's Aliens vs. Predator will hit on Monday.

SEGA "will also have news on an additional feature... many of you have been waiting for which is now ready for a closed Beta test!"

This is most likely dedicated server support, which was said to be close to beta last Tuesday.

Patch Notes

General:

• Stability improvements to address rare and infrequent hangs
• Implemented a workaround for missing audio issues with certain hardware (SoundBlaster X-Fi, Realtek onboard, etc.)
• Fixed save games being lost or corrupted if connection to Steam is lost or if user switches to offline play

Multiplayer:

• Fixed XP being incorrectly affected by offline play (though only in the local stats; this will be corrected next time you connect to multiplayer)
• Fixed other players sometimes appearing to have the wrong weapon or continuing to fire indefinitely after dying
• Fixed rare issue where players would be temporarily invisible
• Fixed some selection of servers and players in menus sometimes being incorrect

Most interesting to me is the not about fixing players continuing to fire immediately after dying. I always thought that was an intentional feature. I didn't mind.

Thanks to Shacker niceguynick for the tip.
