Tiny Tina's Wonderlands & New DLC on Steam Thursday

2K announces that Tiny Tina's Wonderlands will finally land on Steam on Thursday, following an exclusive run on the Epic Games Store. This also mentions a third Mirror of Mystery will be released at the same time with the release of Molten Mirrors, a new DLC pack that's part of the season pass for the dungeon-crawling looter-shooter. There's a FAQ on the Steam release, including details on crossplay support. There's more in this post on the launch of Molten Mirrors:
Break into a heavily fortified prison in Vesper's third Mirror of Mystery, debuting on June 23 alongside the Tiny Tina's Wonderlands Steam launch! Deep within his mountain stronghold, Fyodor the Soul Warden lords over his horde of lost souls.

In order to break their chains, you'll need to work past his murderous mechanized defenses, including terror-powered turrets, blazing furnaces, and bone-crushing hammers. But keep your wits about you, lest you become yet another of his captive souls!

Vesper seems particularly keen on you putting Fyodor in his place, though her motives remain shrouded in mystery—for the moment, anyway.
