The map Castle features a teleporter maze and numerous floating objects. The jumps are quite easy, but allow for shooting and turret-killing from every side. The spawn points are loaded with mid-range weapons like the Needler and Spiker, A sword, and instant respawn spiker and sticky grenades. Allowing you to unleash the purple mist along with sticky blue balls whenever you feel like you're within distance. There is also a sniper spot at the top-most bases and a sniper rifle waiting for the first person up.
The different bases are marked A and B. A for attacking and B for Defensive paths.
The map is to be played on CTF B&W Knights (Black and White Knights). Justly named because the flag-carrier is near invincible and turns white when carrying the flag, and because the few custom power-ups on the map make you closely matched and black coloured.

B Sign Base which is closer to the spawn points than the other
A Sign Base, Which you can see the starting point of at the lower range of the screenshot.

Terribly hidden custom power-up

This map'll have you jumping through hoops to score points!

And occasionally over them!
