Battlefront.com has released an updated demo for Combat Mission: Shock Force, allowing you to try out their strategy game that depicts a hypothetical near future conflict between NATO and Syrian forces in Syria. This demo includes three scenarios which can be played as either US or Syrian. It also offers a fourth scenario, "Demo Training", which was designed to only be played from the US perspective. All multiplayer modes are active (TCP-IP, PBEM, Hotseat) and you can access the full Game Editor, but the save function is disabled.
Update: the Paradox and GamersGate versions of the latest patch for the game are now available.
