Steam is giving away two very different but equally worth-claiming PC games this late May — a brutal turn-based 4X strategy set in the Warhammer 40,000 universe, and a deeply satisfying car repair sim with over 1,000 interactive parts. Both are free to keep permanently on Steam, but their claim windows are short and end on different days, so act fast on both.

What Is It?
Set on Gladius Prime — a colonized planet where ancient relics awakened something terrible — Warhammer 40,000: Gladius is the first-ever turn-based 4X strategy game set in the Warhammer universe. Four factions wage relentless war for planetary dominance with no diplomacy, no alliances — just constant conflict. It’s the classic 4X formula (explore, expand, exploit, exterminate) driven entirely by combat.
Key Features
1. Four Iconic Warhammer Factions
Choose from Space Marines, Astra Militarum, Orks, or Necrons — each with a fully unique playstyle and technology tree. Every faction approaches conquest differently, so no two runs play the same way.
2. Randomly Generated Worlds
Each match generates a fresh planet filled with hidden artefacts, special terrain features, and hostile wildlife that threatens troop morale. Securing powerful relics scattered across the map gives you a meaningful edge against rival factions.
3. Hero Units with Equipment and Leveling
Recruit hero units with distinct special abilities, equip them with everything from advanced grenades to ancient relics of war, and level them up into true champions that can swing the outcome of entire battles.

What Is It?
Car Mechanic Simulator 2018 is the third entry in the best-selling CMS series, putting you in charge of a growing auto repair shop. You take on client jobs, diagnose faults, disassemble vehicles down to individual components, replace parts, and reassemble everything correctly. Beyond standard repairs, you restore classic cars found in barns and junkyards, tune engines, apply paint jobs, and flip vehicles at auction. With 40+ cars and over 1,000 interactive parts, the detail is what the series is built on.
Key Features
1. Full Disassembly and Repair System
Work through every repair job methodically — identify faults, remove components layer by layer, replace or fix parts, and reassemble correctly. The 1,000+ interactive parts across 40+ vehicles keep experienced players engaged well beyond the tutorials.
2. Barn Find and Junkyard Modules
Hunt for hidden classic vehicles buried in barn lots and junkyards. These abandoned cars arrive in rough condition and require full restoration from the ground up — diagnosing, rebuilding, finishing — before they’re ready for your collection or the auction.
3. Tuning, Painting, and Car Auctions
Customize cars with performance tuning and full paint jobs, then sell them at in-game auctions for profit. The Car Editor even lets you design and add self-made vehicles to your garage.
