the sky texture itself is just a standard one - it's in pak0.
I did write a new shader for it - to get a different lightangle, but it should work...
I give it a 7 :o)
I already have the 3wave ctf pack by the way.
For the play I would have given it an eight. But it looked. no offense, completely awful. The corridors from dm11 (or a lot like them anyways) were taking and put with the construction platform like things, that was acceptable, but the metal-girder like pillars looked awful if you asked me and a dirt floor?! I thought this map had a tech theme dirt doesn't fit fyi.
Still worth downloading but only if you can find/make a server to play on because bots aren't all that great. They did get the haste though ;) (Plus imo haste is just a great powerup as its the least powerupish of the bunch)
7 outa 10!
