I was logged in with my Assasin for a log-in event and got a invite to a low level PvP room and thought 'why not?'.
And after that it was basically me trying to figure out how to combo with my Assasin with the adjusted in-game gravity, finding out that I was fighting alone because my teammate went afk, and finally starting to get a grasp of using Assasin skills when both opponents leave the room :P
Edited out parts where I'm just running around, which tends to happen often when there's only three active members participating in a map.
