Just some asshole.
I'm under the impression this game with the "Half Life: Anthology" set, as I'm unsure of how I would have played this back in the day otherwise.
Either way a very fun mod. From what I remember you are tasked with getting something or changing something in certain times and are teleported from place to play in order to achieve that.
I can't recall much about this Mod as I haven't played it since it's release and have since switched to Linux (modding on HL is very archaic as it is).
9/10
Solid mod.
