Pros:

Everything

Cons:

Nothing

Conclusion:

100/100 i loved every second.
Note: i fully appreciate the approach Valve takes in their maps (you want everyone to "get it" and have fun while surviving a Zombie Apocalypse) and i love it. that said, just like in the case of Dam_It, i personally much prefer the real life approach where it's dark, confusing, scary, intense. ..in short: all the elements you would EXPECT in a REAL Zombie Apocalypse. Detour Ahead has it. Big time! you guys rock the planet.
