Thought I would convert Face][ to CTF4 but I decided to redo face to make it a little more strategy based. I have added some ramps in below with jump pads and basically made things a little different. Longer approach to the base with a larger middle section for battles. It eats up the FPS so it may not be converted to CTF4 as this will be even worse. We shall see :-) 

Thanks to Innox for giving me permission to modify this map, I think he was pleased with the outcome :-)
