The map's premise confused me a little at first, since the level progression didn't make any sense; traveling through scenes of 28 Days Later, the Haunted Mansion ride in Disneyland, the Mines of Moria, some jungle from TinTin and then Evil Dead. It wasn't until the end that I realized what the map was trying to convey, and to that end it worked pretty well. Some really nicely implemented ideas impressed me, this is definitely worth a play through if you can. And yes I am aware that there's a Haunted Mansion map for Counter-Strike already.
Also, Captain Combat Beard's mic broke halfway through the campaign which is why he's silent towards the end.
