This map is OBVIOUSLY based off of the first single player level. This was intentional. I enjoyed playing it in single player, so I made a deathmatch equivalent. This map is 100% original work, aside from valve's stock content. The brushwork is 100% original. This was not ripped from the SDK. If you think it was, then you are a fool.

I've been waiting to release this damned thing for a long time. I'm happy with the end result. Have fun, enjoy it.
