It is office but flipped 180 degrees. This will mess with your mind the first few rounds but then it becomes better. This map is great for those Friday night beer sessions.
Office is a great map to begin with so there is not much to say about that but flipping it is a very good idea.
I think that if you had worked a bit with textures and decals and made it your own it would have become even better. Now the "only" thing you have done is to flip it and adding a car basically.

Rotate the map won't do the trick. You have to mirror it.
Ok, it is as simple as rotate it, but it is not the same effect.

Pros: Pro quality :)

Cons: No radar

Notes: I give it a 10, just for the concept. It is so simple, so obvious but never done before... Great !

The better you know office, the worse your gonna do on the map, thats the beauty of it.

if a complete n00b came onto a server playing this he would have the adantage of not knowing the map..

the veteran cs / CSS player tends to jump into halls facing backwards and getting owned by n00bs.

this has to be one of my all time favorite original map remakes.

I think you mean valve gus, turtlerock was CZ
