It’s a new year and that means Diablo 3’s Darkening of Tristam event, which encompasses Diablo 1 remade as an entire dungeon, has returned. The event will be live for the entire month so hop in now if you’re interested.

The Darkening of Tristam features many of classic bosses and locations that defined the first title. However, that’s not all. The dungeon has a pixelated filter along with along other enhancements to make it decidedly retro. Even the sound effects, music and loot are straight out of the 90s. Completing the event has its share of other rewards like transmog skins for the old-school Butcher’s Cleaver, a new banner and new portrait frames. You can learn more about the event in this official post.

Diablo 3 is currently in somewhat of a weird stage with the latest balance patch expanding the number of builds that players can use but the demand for new content still being high. Blizzard promised some new information this year so stay tuned for any updates.

Blizzard Entertainment’s Diablo will be celebrating its 20th anniversary soon and as promised at Blizzcon 2016, there will be a special event in Diablo 3 to commemorate. The Darkening of Tristam is actually a dungeon that features the first game’s 16 levels which have been remade with assets from Diablo 3.

Along with a filter that pixelates everything, old-school sounds and eight degree rotation for the camera, you’ll also be unable to run. To enter the dungeon, simply locate some cultists in Sanctuary, take their missives and enter the resulting portal.

The Darkening of Tristam will arrive in patch 2.4.3 and will also bring other quality of life changes including Greater Rift refinements. You can check out the latest video from the development team below to learn more about how the event’s creation came about and what to expect.

Diablo 3 has even more content in store this year with two new regions and the new Necromancer class. Stay tuned for more information on when the Darkening of Tristam patch goes live.
