Pros:

Challenging gameplay, finale, navigation
Decent concept

Cons:

A few bugs here-and-there
    - finale map crashes on first-load spawning characters
   -sometimes you spawn outside a safe room
   - saferoom doors don't always work

Also, bot players don't always follow you, have to be checking your 6 constantly to make sure they are there.

Conclusion:

Entertaining enough. I gave it a high score to balance out all the haters.
