The concept is that you have two bases, obviously, which are separated by a wall, which can only be cleared by laser jumping (which, personally, I've never been able to clear it in one laser jump) or using the launch pads. In between the two halves of the walls is a pit of lava, as well. Also, each of the walls have little pillbox holes which you can go into in order to pick off opponents who are flying across, or the ones who are going for the strength, which was placed right in the middle of the lava.
Also, each base has a warp to a pillbox - a pillbox containing a nex - stationed right outside the opponent's base. However, other than taking the return warp back to their base, they're stuck in there with no health powerups or anything, so it's a bit of a risk to go into it.
I really wanted to make this map, since there seems to be a definite shortage of large, outdoor CTF maps - which are definitely my favorite types of map to play.
Right now, the map is perfectly playable, though with some problems. There's some obvious drawing issues outside the red base, which I'm not sure how to fix, since I'm a pretty big noob at mapping. If anyone can help me figure out my issues with it, I'd appreciate it. I'm also open to any critiquing you can give, since, like I said, I'm a noob.
