You're supposed to go into DefaultRoutine.cs and change "behave = new BehaviorControl()" to "behave = new BehaviorRush()"... However, I tried it and didn't notice a difference in play.
Behavior behave = new BehaviorControl();//change this to new BehaviorRush() for rush mode This is what i see in the file however I am still unclear on where to put "behaviorRush"
