Pros:

Mix of Portal & L4D
Custom textures
Custom models
Customs sounds
Custom voices
Custom music
Training with a storyline to it as well
Re-train as much as you'd like before proceeding to the next area
NPCs that move around
Easter eggs

Cons:

Some graphical glitches with some NPC animations.
The campaign is not finished yet

Conclusion:

I love this map. It not even finished yet and it's awesome. There have been previous Witch training maps but this is exceptionally better in so many ways.  I love the custom voices , it sounds like things I would say joking around. I can't wait to see the rest of the campaign. Fantastic job Tisa :D

Pros:

Mor-ning Lescue....Mor-ning Lescuuuue XD
Engrish Audio

Cons:

You don't actually get to drink it :p

Conclusion:

I don't normally use audio mods, but this was pretty funny. Those that don't know anything about "Engrish" probably won't get it.
