Pros:

- Very replayable 
- Fun with friends
- LOTS of tanks, LOTS of infected
- Very creative map

Cons:

- Bots never heal themselves
- The submarine part was a little confusing

Conclusion:

A very good time consuming map. I spent 38 minutes playing this map with Bots. We killed 2138 common infected, and 83 tanks, not bad for 38 minutes of killing boredom in my book. 

I found the 3 or 4th part of the map was pretty nice having a "Revive dead survivors" button.

The ending was.. interesting if I have to say so myself. I found it surprising at first, but then again, it is called a "survival map" after all. hehe.
