Hey, it worked out, I just installed the game using his account and logged in, using offline mode. He logged in using online mode, and we were both able to be in game at the same time. Now, my last question is, how can I launch BL2 without even opening steam? Or is it possible for me to set launch options for a separate Steam.exe where it will launch the client in offline mode, log into his account, and launch BL2? Just being able to launch the game without Steam would be even better. Thanks.
