Bungie had put the Iron Banner, as well as the Trials of Osiris, on hold last week after players discovered an exploit that allowed them to generate unlimited ammunition for some of Destiny's most powerful weapons.
"We're pleased to report that our work on that front is done, and [that Lord Saladin] has been granted clearance to set up shop at his usual haunt in the Tower," said Bungie in a blog post.
This week's Iron Banner will run until the next weekly reset, which will occur at 5 a.m ET on Tuesday, May 31. Iron Banner combatants will be able to earn gauntlets (including PlayStation-exclusive ones), chest pieces, sidearms and fusion rifles. Players who don't have fireteams to fight with can try Bungie's Recruitment forum.
