Blue Shift was a short lived expansion which saw you take control of security guard Barney Calhoun, who is stuck in the middle when things kick off. Although not on par with the original game it was entertaining while it lasted. So, if you’re someone eligible to get it for free then we recommend you give a go.
Disappointingly the game has not been revamped with the new Source engine. When originally released the expansion came with an improved model set that could also be used in the main game. Blue Shift should be available to download on Steam now.
