Pros:

1. Good map design
2. Love the details on few roomes
3. Nice garage
4. Slow-motion!
5. Many gas-cans etc
6. L4D1 Survivors! :D

Cons:

1. Slow motion was is a small cheat, since the clock doesn't slows down :P
2. Too bright when switching the slo-mo
3. Too few melee
4. Some rooms need a little more details.

Conclusion:

This is one of my favourite survival maps for L4D2!
