You are immersed in a very similar story to that of Half-Life. You will also notice a slightly better artificial intelligence and a new weapon model. 49 maps total. You will also notice a new obstacle course, there are always beginners ;-) This was originally created by Fresh (See readme for contact details)

Really great mod.
However, it for the most part a slog-fest of looking where good' ol Fresh hid the exit to an area.
Quite honestly, I never legit figured out all the puzzles- since I most bypassed them by using Speed-run techniques, eventhough I'm not speed running.
For the most part, it was fun if not a bit dragging at some points.
