Seventeen:

Seventeen was created by MetaWaddleDee and A RedBull Can. This map is compatible with every game, but recommended for asymmetric gametypes.

Description:

Seventeen was created for the Template Contest. It consists of a defending base, an attacking base, the banshee base, the center structure and cover in-between. There are Overshield and Active Camouflage structures with a few other structures that hold different equipment, and weapons. The Banshee only spawns in asymmetric gametypes, and the Spartan Laser spawns in Symmetric Gametypes.

(overview)

Red Base (Defenders)

Red base consists of a shotgun, a Missile Pod, a Plasma Pistol, two plasma grenades, and two BRs. Vehicles with the exception of the mongoose, cannot enter the base, because of the columns in the front and back of the base. These columns are spaced out as to only allow the players to pass between them.

Blue Base (Attackers)

Blue Base consists of a Plasma Pistol, a Missile Pod, two Plasma grenades, two BRs, and 2 Carbines. Again, Large Vehicles can't enter the base, due to the size of the entrances.
