The blueprints look like the playing field.
Here's the map with contrast increased, skewed to correct angles, and lines traced:

As you can see, it looks like there are two catapults or trebuchets-- one on each end. Appears to be two "strongholds" in the center, along with two smaller "buildings." Along with a truss on each side, like the 2014 game.
My guess from this is it's a projectile game, where there will be towers in the center, and the teams will have to use some sort of provided ammunition to knock down the opponents towers. (images attached too in same order)
