Just finished a run of Heroic Zero Hour where one person needed the catalyst and two (including me) needed to do the vault puzzle. The shredder robot had it out for me, I had pretty much given up hope on this run. One fire team member started inputting codes, the other goes to boss room. I finally get to the vault with about a minute left and we somehow get all the codes in. We run down to boss room and our boy has soloed the entire room. This was his first heroic run. Exhilarating is an understatement. Pure adrenaline straight to the heart. Was so satisfying as well. That’s what games are supposed to be: fun! Just figured people could use a reminder occasionally given the mood on these forums sometimes.
