Heyyo,
You can already get my as_highrise waypoints at my website:
http://www.freewebs.com/mard_lltd/ take a look over the elevators... I'm also fine-tuning my de_aztec2 waypoints, just have a few jumps to fix. Lol, I noticed one, to the right of the CT spawnpoint, they'll leap out the open viewport, n' if they get in combat, won't follow their jumpwaypoint, n' hit the land n' die... so I'mma angle it better to prevent this.
Me? I love de_rotterdam, used to play it all the time with good ol' PODbot v2.5... ahh, those were the days, back when I had an old 3dfx vooodoo 4 pci, n' when I was still a n00b, n' bots had higher scores more than I did.
