i kind of remember playing a mod for a different game that was kind of like half life
it was hyped up at the time, but can't remember what it was
pretty sure it was a half life 1 remake in a different engine, and was a mod for that engine?
edit: was probably black mesa, but doesn't say i've played it, so i guess a mod recreating black mesa
but it's not free I'm borrowing it
it is currently free
free to borrow, not free to keep
you are not being charged by valve to play it
