There isn't a max character level. There is a weird issue, for me at least, where my level after finishing a scenario or service is different to the level on my profile and that displays in the top right corner of the main menu.
I'm at level 61 Want to make it to level 100 so all you noobs can feel pwned by a furry. But i'm running out of scenarios and services, even with all the DLC.
Damn! I thought level 204 was good ...... but 400? Hats off to pschlik Must be writing all those collectible guides that did it!
