Took a 15 second run through the map, couldn't stay long because Pball's wrecks my computer if I play too long.
But back to the map, I found it a pretty cool idea with the spiral slopes up the tower. Only one thing though, is that the only way up? If it is, that'll be really hard to capture the flag, because just one base camper will pretty much keep the flag protected.
EDIT: Found another way into the base. Good job with the map then. For now I can't find any faults. XD
