In an act of generosity, Half Life creators Valve have permitted for the fan made remake of their original title to have a commercial release. The development team announced this on the Steam Community page on the 15th birthday of the original game, with a statement citing the exact reasons for the price tag which will be attached to the title: “Our decision to sell Black Mesa rests on two key points. One is we believe we can make the game even better by having full access to the Source engine. This lets us tackle and fix limitations instead of working around them. The second is because frankly, our team could really use the financial help.”
