I can say that I am still playing through this with mates, still enjoying it too!

Just above lvl30, getting towards the end of the lab quests. Main quest progression about 80%

I have about 6 mates who I play with, so I am regularly playing in lower-lvl sections etc to catch the lower guys up

Fairly well made game though IMO. Fairly challenging and even suspenseful in some parts.

Next game on the cards will be that Heist game, then Saints Row 3
