Bungie has revealed that Season 2 of its first-person extraction shooter Marathon will begin next month on June 2. Ahead of the new season, the team has detailed the finale update for Season 1, alongside information Runners should know about the progression reset and more.  Season 2, dubbed Nightfall, begins on June 2, but before that, Bungie says UESC security (the NPC enemies in the game's various maps) efforts will be renewed and amplified in the final days of Season 1. When update 1.0.9 launches on Tuesday, Runners will find that locked room keys are guaranteed to drop from Wardens for the remainder of the season; plus, map events like Intercept, Lockdown, Warden Spawns, Convoy, and Anomaly will also be guaranteed on each run, allowing you to benefit from better rewards more often.  You'll also find new Warden encounters at new points of interest on Perimeter, Dire Marsh, and Outpost, alongside an increased presence of UESC dropship flyovers and crash sites.…
