Bungie released Marathon's big mid-season update just a few days ago, and it's packed full of heavily-requested changes (plus a bunch of new things we didn't even know we wanted). There are more unique weapons to find outside of Cryo Archive, the CARRI event designed to incentivise cooperation, an experimental pseudo-battle royale mode that's a real treat, and a new item: the Mercy Kit.
In Bungie's own words, "sometimes you shoot first and ask questions later," so the Mercy Kit is intended to, y'know, let you show your enemies some mercy if there's a chance you could be buddies after all. All Rooks spawn with a Mercy kit, and there's a chance to find one while looting in your non-Rook matches.
