How to get fast xp?

Or you have below 2.500 and/or you have poor killing skills and you just mop every stain.

Or you buy an glass shard and go to the hitman (tip, kill the patients usually between 10-15 level, as the newbies tend to go out of the patient area, and get captured by the guards easily. And too high ranks will just kill you faster than you can kill them

Try escaping . Here is an easy way to escape. Make sure you have a stolen staff keycard, you can get this by searching a trash can. Then go to the tool shop and buy a "Crowbar" After that go to the vent above the fighting arena, and click "Cubic Reception" Then use the staff keycard to open the door, also open the door that leads to a lot of stairs, run up them but save some stamina for when you get up. After you have reach the top of the staircase then run to the exit, there will be three doors in the way, this is also where staff spawn so be careful. After opening the doors run straight and if your being cased then try dodging. Run untill a cut seen shows, then get your reward. :D
