Pros:

For connoisseurs who appreciate the good.
For young people who did not know the Quake 2
A remake worthy of admiration
Do not let a single detail.
Survival with circuit
Added extras such as the generator or the elevator.
Good atmosphere
Multiple ways to survive

Cons:

Lack debug the shadows
Missing water sewer xD
Little optimizing of map.
Lack Hook Mod (hehehehe)

Conclusion:

It's been a great revelation for me and I am convinced it will be for many more being able to play the most played map of Quake 2, reviving in this way has been such an experience for me and my friends were to become one of the icons of L4D.

However, remember that even that is a 100% plyable map (at least apparently) there is much work to do ... not misunderstand me, just have to debug and optimize the map for a better load, otherwise everything perfect.

We are eager to take out new revisions for L4D1 and L4D2 with Versus and scavenge modes.
