Ok so the first update. Actually looked at the secert ingredient and worked it into the build. The objectives will themed one winter, one grassy and one city. The black one is going to be the grassy one. I plan on building a tree coming out of the plasma gun base.
Winter
City
Grassy with tree
For the turrets im going to use the paper tube as the main support. Then Im going to bury it with pink foam and sculpt out an embackment from it. Some secondary support will be fashion and what not. Hope you like where this is going. I mean with planet strike coming out where going to need some gaint turrets
Inferno Cannon turret
Laser Destroyer Turret
