Borderlands 3: The Sword and the Gunslinger

[Part of the Wasted Land story]

The next key pieces are on the planet Promethea, home of the Atlas corporation, but it too is under attack by both Maliwan and COV who are in clear alliance. Fortunately, Lilith knows of allies here as well, the first being Mad Moxxi who distracts most of the COV by participating and winning the galaxy wide broadcast of "Who wants to bang a bazillionaire" in nearby Lectra City, basically an all female city wide death match with the winner being able to bang the host in front of a large audience, both broadcast and live (with much audience participation to boot).

Lilith's second ally in the area is the space ninja (warframe?) Zer0 who makes use of the Sanctuary III to assault the Maliwan orbiting death star to end the war and earn the remaining key parts that Dr. Tannis needs to finish the key.  Maya volunteers herself to open said vault where she defeats the impressive guardian monster within only to then encounter the Calypso twins. While Tyreen absorbs the power of the defeated monster, Troy absorbs and disintegrates Maya herself.

While they replay her snuff film on a loop, Dr. Tannis discovers that this vault seems to be linked to another on Eden-6, the swampy home world of the Jakobs family who are also in conflict with the COV. They hire a trusty gunslinger squire named Clay - the lone merc who didn't simply take Calypso money and leave like a whore.
