Is Half-Life Decay Black Mesa Airfield available on PC?

What does the ModOrNot Score mean on this page?
It is a 0–100 momentum signal: 50% subscriber-growth velocity relative to mods in the same game, 20% favorite growth, 20% view growth, and 10% update recency. It is not a quality rating. A recent score is unavailable for this mod, so no estimated value is shown.
