Publishers Deep Silver and Nordic Games have partnered with GOG.com to release DRM-free version of Metro, Saints Row, and Darksiders games for the first time, the companies have announces.

Five DRM-titles have been added to the GOG.com’s online store today, and they’re being offered with celebratory discounts until May 18:

Metro: Last Light Redux (-50%) – The 2014 remastered re-release of the first person shooter set in post-apocalyptic Moscow.

Saints Row 2 (-60%) – The open-world action-adventure crime game.

Saints Row: The Third (-66%) – Where the series ventured even further into the absurd.

Darksiders 1 + 2 (Up to 75% off) – The Legend of Zelda inspired adventure where you play as two horsemen of the apocalypse: War in the first game and Death in the sequel.

“It’s not every day that we see major games like these, unchained from any forms of DRM,” GOG.com VP of business development Oleg Klapovsky said in a statement. “With today’s big-name DRM-free releases, and the impending The Witcher 3: Wild Hunt premiere, we anticipate even more major titles to follow suit.”
