Thunderwalker 2 was a CTF mod from some of the same guys (Team 3 and D Team) that worked on the Allstar 2 map pack.
We have some of the TW2 maps on the server already: Warhouses by Hafhead (the screenshot is from Warhouses: how about that sunset!), The Swivel Frit, The Cataclysm, Lords of the Ring. These are big maps!
There were also 4 “small” Thunderwalker 2 levels.
Here is link to download the .pak containing these levels (named tw2small1-4.bsp): http://www.fileplanet.com/13168/10000/fileinfo/Thunderwalker-Levels
