One Task Force Operation's Mission Control refers to one location as being north of another.This is likely to prevent players from getting horribly confused and turned around, but it also does make 'vertical' attacks difficult to pull off this unfortunately makes escorts, with their narrower firing arcs, a bit harder to use than they probably should be. The main problem is that the ships are limited in how much they can pitch up or down (to about 75 degrees relative to the plane of the ecliptic) and are unable to execute any kind of rolling maneuvers other than banking during turns.This does not have to be all bad though, since it eases orientation for players. There also is a defined 'up' in space, meaning instead of moving freely in all three, you may only move two dimensional with a little height difference. While there are three dimensions, the up-down is severely restricted in scope and way smaller than the others.
