Mod was good prior to the Last Stand update. Now it's completely broken.
I captured two videos of how the AI works.

- If you shoot at a Special Infected, they won't aim at it. They stare at you instead. Valve's original coding takes this into account so the bots are able to target Special or Common infected with your help.
- They won't help you if you're incapped. They stand there without firing at the infected.
- They teleport away from the player during finale levels. It doesn't always happen at the exact finale, it happens on the way to the radio's place.

Some of the servers that has this mod installed had their bots warping out of bounds when players needed them the most. They don't run over to where the player is, either.

All in all, this mod is super broken. I wouldn't recommend it at all.
