Pros:

Bots don't shoot through you anymore
I like that they can close the safe room door and use their kits on me before themselves.

Cons:

When they lead they walk into your line of fire more
Clipping through doors during finales
They still seem to lag behind a lot, get stuck, lose their direction, especially when getting to safe rooms.
Running ahead made them startle the witch a lot.

Conclusion:

Overall, it was more annoying than useful. I uninstalled it after one play through.

Pros:

Gratuitous swearing
Loud
Funny lines

Cons:

None

Conclusion:

This file is badass, laughing the whole time as I shoot the shit outta that thing.

Pros:

Interesting scenery
A few good scary moments
Items and ammo dumps were well dispersed

Cons:

Items were clipping through tables
Too many loop backs while navigating the maps
Lack of melee weapons
The storyline attempted was interesting, but it didn't really play out well to the finale.
The last map looked sloppy, unfinished, and was too large.

Conclusion:

Played this with a friend for the first time, I liked the idea of the voice mails explaining how the virus started. I was excited every time I found a phone, but there was no conclusion and it left me wanting more. While navigating the maps, there were far too many areas that looped back on themselves and I kept getting turned around and confused, I feel it should be more linear. In the finale, the whole set up was supposed to look like an unfinished construction project, but it really just looked like an unfinished map where he threw in random concrete walls and iron girders. The map seemed far too large for what was needed in the finale, all we did was hang next to the helipad on the mounted gun and we breezed through it. When the helicopter came, my friend discovered you can just run right through the back side of the chopper. Not to mention our bots got stuck in a big pit in the ground so when the tank came, he just knocked us out of the helicopter, through the back, and we were in-capped upon hitting the ground.

Overall this map has potential, but currently I wouldn't play it again unless it becomes updated.
