Attack and Defend variant!
New players please read the following:

Red have 60 seconds to set up their defence before Blu are allowed to attack.
Defend the middle point E - under the rocket - until the time runs out!

Objective:
Blu must capture Red's middle point at E at any time to win the game. Taking the surrounding points will help make taking the middle point easier. The five  points do these things:

A) - Opens a quicker routes to point E and D
B) - Moves Red spawn point further away from Blu. (between C and D)
C) - Extends 3 bridges toward the middle point
D) - Blocks Red's spawn exit to point E and extends handy rails to E.
E) - Blu can capture this point at any time to win the game

Other Notes:
Control Points cannot be captured while they are locked.
