Next server restart will add Extra Ramps, Wedge Bricks, Round Corners, Random Brick Pack, Inverted Corners, and Grill Plate bricks. We're also considering developing our own brick pack.
I've also added about 30 different slate maps but that's not important. I'm not currently planning on adding any lights or particles at the moment.
The server theme will also include a small number of appropriate add-ons. Probably a vehicle and a few weapons.
