was wondering how to get into that one club area since its locked and the guard tell ya to piss off
Ah, ok. Yeah those are all about speed, prioritizing the right enemy, and maybe just a bit of save scumming. Don't just blindly attack: pay attention to where your multi-attacks land, and if one guy's about to go down, sometimes it's worth it to prioritize rushing him with a regular attack rather than waiting for your multi to recharge.
