So I finished the map. Everyone, I'd like you to meet cp_linear-a 3 Point Attack/Defend map, featuring a desert akin to cp_badlands, in a sense.
That is BLU spawn, with all 9 Mercenaries ready to go. As you can see, their bottoms denote their teams, and the tops are their classes. Scout is Light Grey, Soldier is Dark Grey, Pyro is Red, Demoman is Brown, Heavy is Tan, Engineer is Yellow, Medic is White, Sniper is Green and Spah is Black. That thing in the back corner is a medicabinet.
Their first challenge is this fun wooden construction. Soldier and Demoman can rocket/stickyjump up there, at the cost of some HP. Other classes have to take the stairs LIKE MEN. Or they can just take the side routes...
Behind the wooden front is a Control Point. It has 24 !!Capture Markers!! on it. Every turn, one will change colour to blue per man on the point. If non are there, then it will tick back... Cap it, and it will stay blue.
Get past that, and you've got this big metal monstrosity to deal with. An aspiring Soldier/Demoman can get to the CP in two rockets/stickies-one to get to the middle section, and another to get to the top. Scout can just do the wanananana straight to the top. But beware of those windows in the background! Luckily, this point caps twice as fast.
Get by THAT and a few crates, and you're into the RED base! With their added mobility, Scouts, Soldiers and Demomen can jump straight from Second Point into the upper windows, but not vice versa. All three can also access the left window with the aid of the crate.
The final point is right outside the RED spawn, but it caps at four times as fast. That upper platform can be accessed with the aid of stairs. Anyway, call your players AND YOUR TEAMS, and I'll sort out the roster for the FIRST ROUND OF LEGO FORTRESS 2!
