this is the refined version of maintain tardis in vortex/long flight mode what happens is in advanced mode when you use long flight or vortex you have to use a few of the levers and buttons on the console every once in a while or if a vortex anomaly is coming which in teh text it will alert you and you have to use what it tells you to do within a few seconds of it telling you it like 29 seconds you also have sheild occilators which protect teh tardis from the vortex they dont protect teh tardis from taking bullet damage or physical damage and when you dont use the levers/buttons to use once in a while the sheild occilators take damage and when it hits 0 the tardis will be more vulnerable to taking damage and you will have to use the stuff on the console more frequently to aviod taking more damage and its possible to not take damage when the occliators are down by constanly using the stuff on the console to aviod it and if the tardis health is low or at 0 the tardis will do emergency landing either or like in the christmas invasion when the tardis emergency lands https://www.youtube.com/watch?v=oF2EmKdTbsc and when you exit the vortex the shied occilators automatliy go back to full health or you could regenerate them in the vortex by using this http://cloud-2.steampowered.com/ugc/579023896580389385/89D1CFB16F0CF207F1A1DC002B335D82275B6914/
