NTU like how it was in Planetside 1 where people have to fill it with ANT energy or else if it goes to 0% the base goes neutral. It gets quite awesome and crazy especially on 3-ways where people are trying to fill from the outside. Sometimes the only way to get into a base like that is to fly the ANT with a Lodestar in Planetside 1. Someone flies, ANT loads in then gets ejected over the NTU then the player with the charged ANT from the Sanctuary fills it.
