With the original Corridors by Adam, I was saying that it needed water a moving sky - and with this second version, that is what we get, which is nice. Mind you, the sky is not a realistic skybox yet, just a cloud-decorated ceiling that glides about a bit, but it is a definite step in the right direction.
This is just a nice map to play. Nothing too complicated or fancy, with the only health coming from the megapower you can possibly see in the distance, and a nearby electroshield. One of each weapon, more or less - and lots of space to hurry about. The Bots seem happy here, without any complicated pathing. So, for a simple, friendly NAB experience, add it to your folder, okay?
