EPIC!!!
Extremely detailed.
Outstanding looks.
Great atmosphere with custom sounds
(don't forget to do the snd_rebuildaudiocache).
Multiple paths (which is in fact a pro for playing it more than once) and some of them are even blocked sometimes like in L4D2.
A new well done escape vehicle.
Cons:
Minor bugs that will be fixed anyway.
Conclusion:
Valve should reward this with an expert achievement!
100 just isn't enough compared to others. So I give it an unofficial 150 :-P
