Welcome to Hard Duty. This is a Half-Life modification with the objective of expanding the Half-Life universe with new content. Explore the Black Mesa Research Facility like never before and fight your way through hordes of enemies! How will you engage the situation? How will you survive?
I'd like some of you guys opinion on what kind of OST you'd like. I uploaded this rock bit as an example of what I can do for you (obviously I will compose something more in line with video game music but the main instruments I would include would be kick, snare drums and the like with electric guitars) - but if you prefer an OST closer to Half-Life, let me know and I'll work on something in those lines if I can.
