Halfy birthday, Hap-Life! Well, I guess it’s technically the day after your birthday now, but an upgraded version of Source-powered Half-Life tribute Black Mesa still counts as a gift, I think. You might remember that the free labor of time, love, and more time was greenlit a while back, but now it’s finally taking the Lab Facility Train Ride of Ultimate Auspiciousness over to Steam. Better still, Gabe and the knights of the Valve table have given it their blessing, allowing the Black Mesa team to earn some especially pretty pennies for their hard work. The Steam version will include new features too, but not Xen. That’s apparently still “a ways off,” sadly.
