Siege of the wood fort.

You can use wood to build a bridge straight up the middle to the big hill in front of the fort to the second COP. At the second COP you can use wood to build a ramp up the right hand side to the fort. At the final cop you can use wood to block some access areas to the COP.
Between the first and second COP there is a ridge line. Atop that ridge are a series of little rock platforms. If you are facing the fort at the far right of that ridge is a tall rock. I have seen someone climb that rock and put a port up there. So, I should be able to climb it and get a gun up there. I'm still figuring out how they got up there.

Yeah putting a gun in that place is popular. As for the 2 CP - you can build a catapult right in front of the gate, and a bridge both on right and left side.

On my Sapper, I never waited for the bridges to be made to have TPs in their base. Lol, start of the match, I will be inside their base with a teleport and totems. xD
