Just need to learn how to make caves/archways/tunnels.
The mid area in front of the ref's/AGT's will be heavily walled off (think orginal mesa cave, and smaller than eyes cave). Ideal goal make it so you can only hit the ref a lot, and AGT/OB require rushs to hit.
Next on the list is adding water, and fleshing out the center cliffside infantry paths that have tunnels that let you sneak into the base.
Fine tuning the placement of the AGT/OB is something I'll need beta testers for. As well as how I handle the bridge paths with Arty/MRLS range on the HON/WF.
