Warhammer 40,000: Gladius - Relics of War, the Warhammer 40K franchise's only 4X strategy title, is free to claim permanently on Steam right now. Owned by developer Blacksmith Games and published by Slitherine, the game sits among hundreds of licensed Warhammer releases flooding the market annually, making this giveaway a rare opportunity to grab a solid strategy game without spending.
Gladius - Relics of War released in 2018 to modest reception but has maintained a dedicated audience. The game adapts 4X mechanics to the grimdark Warhammer 40K universe, letting players build bases, research technology, manage armies, and conquer planetary territories across turn-based campaigns. It's Civilization meets Warhammer lore, complete with faction-specific units and asymmetrical playstyles representing Space Marines, Necrons, Orks, and other iconic forces.
The 4X subgenre rarely intersects with licensed IP outside niche titles. Most Warhammer games lean toward action, tactics, or real-time strategy. Gladius remains the franchise's sole full-featured 4X offering, giving it historical weight within the broader license ecosystem. Despite releasing seven years ago, the game still delivers hundreds of hours of replayable campaigns through its faction variety and scaling difficulty options.
This free offer matters. The Warhammer 40K license generates massive revenue through annual releases, yet quality varies wildly. Giveaways like this expose players to deeper, less mainstream titles before they disappear beneath newer releases. Blacksmith Games has supported Gladius with DLC factions and expansions, but the base game alone justifies the zero-cost barrier.
