Disclaimer: I only won AoRA on HNTR.
Treat it like AoPc but with the ability to kill things. Kill as many things as you can to level up, but if you find the stairs, do not hesitate to just go down. You are virtually confirmed a kill on Cybie if you can get to Phobos Arena due to the nuke. I won my HNTR AoRA with my basic MGK build, peaking out at level 7 when I faced Cybie. You will definitely want the movement speed, especially when you are first trying to find the stairs -- do not be afraid to strip just to run to the stairs. Play conservatively, and think about how you can get to the next level as opposed to doing a YAAM run. For reference, my kill rate was only 57% for the run that I won.
Hope these will help you a little. I'm sure the other more experienced players will have more to say.
