So i am making a juggarnaut map and need to be able to prevent the juggernaut from accessing the spawn area (i want to only have one spawn area for the non-juggernauts) is it possible to make a kill zone that only effects the juggernaut (Blue team)?
This. Unfortunately, nothing in Reach is team specific (except for objectives and vehicles in race modes). The one way shield will be your easiest option (but the least aesthetically pleasing [usually]).
