Three exceptional cooperative games, featuring a widely praised space sandbox title with overwhelmingly positive user ratings, are currently available at no cost on Steam through September 1. This generous offering follows shortly after Steam's free distribution of Dead in Bermuda, now expanding to include an impressive selection of free-to-play titles renowned for their outstanding cooperative gameplay experiences.

The cooperative gaming category has experienced a remarkable year on Steam, with recent statistics demonstrating that many of the platform's most successful titles emphasize collaborative gameplay. Breakout hits such as PEAK and R.E.P.O. clearly indicate substantial player demand for cooperative experiences, with gaming enthusiasts actively seeking more titles in this genre. Valve's digital marketplace appears to fully recognize this growing trend, surprising the gaming community with an impressive lineup of popular cooperative titles.

Currently Available Free Co-op Games on Steam

• Space Engineers
• SWORN
• Unrailed 2: Back on Track

Through September 1, Steam users can enjoy complete access to Space Engineers, Unrailed 2: Back on Track, and SWORN without any cost. Purchasing these three titles normally would amount to approximately $60 USD, presenting an excellent opportunity for players to evaluate whether these games justify their standard pricing. Each title offers extensive cooperative gameplay mechanics, with Unrailed 2 even incorporating competitive elements where players can challenge other teams within its cooperative framework.

SWORN presents players with an isometric action roguelike experience supporting up to four participants. The game's fundamental mechanics involve clearing procedurally generated levels, drawing artistic inspiration from Mike Mignola, the renowned creator of Hellboy. In contrast, Space Engineers delivers a science fiction sandbox environment accommodating up to 16 players across both cooperative and competitive modes, where participants construct bases, explore unfamiliar territories, and struggle for survival against the merciless conditions of outer space. Unrailed 2: Back on Track completes the trio with its top-down perspective adventure centered on railway construction across dynamically changing landscapes, each presenting distinctive obstacles and challenges.

Steam has additionally made Nightingale available for free play throughout this weekend. This title offers an open-world survival and crafting experience incorporating online cooperative features. However, the game currently maintains Mixed reviews from users, making this free period an ideal chance for players to experience the game firsthand before considering purchase. Forts also joins the free-to-play roster on Steam and, unlike Nightingale, has achieved Very Positive review status. The free gaming opportunities extend beyond these titles, as players interested in solo adventures can also sample Darkest Dungeon 2, widely considered among the finest dungeon crawling experiences in recent gaming history.

The positive developments continue with most of these games receiving substantial discounts ranging from 30% to 75%, allowing interested players to acquire them at significantly reduced prices. Space Engineers, for instance, currently sells for approximately $5 USD, representing exceptional value for a game celebrated for its extensive replayability. Unrailed 2: Back on Track enjoys a 30% price reduction, decreasing from $20 to $14. Both Unrailed 2 and SWORN remain in early access development phases, with SWORN scheduled for complete release on September 25. While no official global release date has been announced for Unrailed 2, the game is anticipated to reach version 1.0 status shortly, having been in early access since November 2024.
