Pros:

Fun map
Obscure Atmosphere
Overall one of the best survival map I´ve played

Cons:

Not being able to go  upstairs in the lighthouse

Conclusion:

This is a great survival map, its only missing one thing to top Valve´s lighthouse and that is a better lighthouse. I say remake the lighthouse probably best to make it smaller so its easier to be attacked by infected and make it accessable all the way up :)
