Pros:

IT IS A PORT OF DOOM!!!!

Cons:

its a port of doom 1 D=

have a FREQUENT problem where we would spawn off map.  Fixed by going idle and porting to bots/ other players but was impossible when the whole team was trapped in the walls.

Conclusion:

Old schoolers (myself and many others) will enjoy this map A LOT.  Those of us that didn't grow up with Doom being highly controversal and mind blowing, sorry, its not for you.  But then again, it wasn't meant to be.  If this had a few more maps (make a Doom Campaign, that would be SOOOOOOOOOOOO sweet) it would be a dream come true for many gamers.  80/100.  -20 points for annoying glitch and lack of special spawning.

Pros:

Many.  

Cons:

The same texture over and over gets boring, but I can at least understand the reasoning behind it.

Conclusion:

Don't play this map with people who like to watch others die.  There are far to many chances to kill your team mates.

Pros:

Custom Messages = Always cool
Custom Tank
A pretty nice fire texture

Cons:

Custom Messages are hard to hear, ramble a bit, and are a bit confusing
The Custom Tank won't stay the hell off the rest of my maps, may have to delete campaign to remedy this.
Confusing as hell as to where your supposed to go (for some people anyway)

Conclusion:

A good overall map with some very  damn annoying side effects.  This one gets a 65 mostly for the yeti tank showing up in every forsaken map in L4d2 now.
