MercurySteam

MercurySteam is a Spanish video game development studio based in San Sebastián de los Reyes, Madrid. Founded in 2002 by former members of Rebel Act Studios, it develops action-adventure games, Metroidvania titles and third-person action experiences for console and PC. Its work spans established franchises and original intellectual properties, combining game design, engineering, artistic production and proprietary engine development.

The studio's early releases included American McGee Presents: Scrapland in 2004 and Clive Barker's Jericho in 2007. It subsequently collaborated with Konami on a reboot of the Castlevania franchise. Castlevania: Lords of Shadow arrived in 2010, followed by Castlevania: Lords of Shadow – Mirror of Fate in 2013 and Castlevania: Lords of Shadow 2 in 2014. These projects established a substantial part of the studio's action-game portfolio.

A later collaboration with Nintendo produced Metroid: Samus Returns, released for Nintendo 3DS in 2017. The partnership continued with Metroid Dread for Nintendo Switch in 2021, extending the studio's work in exploration-driven action games. Alongside these collaborations, MercurySteam developed and self-published Spacelords, which initially launched as Raiders of the Broken Planet. Its original projects also include Blades of Fire, developed in partnership with Digital Bros' 505 Games, which published the title.

MercurySteam's production capabilities cover the development process from pre-production through post-launch work. Its teams handle mechanics, level design, system architecture, graphics and physics engineering, character modeling, texturing, rigging and cinematic animation. The studio also integrates soundtrack and sound design and optimizes games for Nintendo, PlayStation, Xbox and PC platforms. Its in-house Mercury Engine supports this development work.

The company combines publisher collaborations with the creation of its own games. Following Nordisk Games' minority investment in December 2020, the studio's founding partners and management retained majority control.
