A full week of fighting?... Sounds like only those with high stamina will survive. On the contrary, stamina has nothing to do with this fight! Instead, you will need to collect 4 new ammos from jobs, wars, robbing, and, should you choose, gifting to bring down Roughhouse.
As for the new ammos, our informants tell us that it would be unwise to assume that any one ammo is the best and use it the whole time. Apparently, the ammos, when used in certain sequences, unlock particularly damaging combos! You will have the opportunity to discover one such combo by completing a Quest Event that will run during the Boss Fight. Other combos, you will have to discover on your own or via your friends’ feeds, if they beat you to the punch.
Get ready, ‘cause only the roughest and toughest will win this Boss Fight!
