I am running a 4th edtion game right now with 6 runners. One is a human changling street sam with an agility of 12 and focuses on close quarter combat with guns like the movie Equalibrium, there is an A.I. Rigger, a mechanic assassin jack of all mundane trades, a urban brawler changling troll adept with cyber legs that can throw anything with deadly force and can run at 60 mph, a medic that has gremlins and magic resistance maxed that uses pre 2012 medic gear, and a occult investigater mystic adept with a crazy high perception. All I have to do is find a way to challange them withut killing them. So far they are going through my runs like they are a walk in the park until I sent them up against a few terrorist suicidel mages and some gun happy lackies which nearly killed them. How do I challenge my group with out whole sell slaughtering them?
