Has bugs.

First level, the door does not open to go outside after climbing the rocks. Second level crashes to desktop. I stopped there. The map has really nice graphics but it appears that it has bugs that need to be fixed.

Crashes plus missing passage.

Only got to level 2 before crashing. Level 1 has no passage to safe room, so I needed noclip to get through. Map is going to the trash bin.

Nice map but crashes

Very nice map, interesting routes, but sadly it crashes to the desktop on level 4 as soon as survivors get out of the safe room and into the first alley, If this can be fixed, it will be a success.

Pros:

Awesome graphics.  Refreshing change from the standard cityscapes. Well placed ammo and health.  Unique props.

Cons:

Need a fast processor and a good graphics card to get the most out of it.

Conclusion:

It's one of the better maps for l4d.  Can't wait to see the rest of it.
