Top 10 Open World Games Like GTA 6 (2026 Edition) – Full Review & Gameplay

If you love GTA's crime sagas, this is your next obsession. Mafia: The Old Country is a prequel revealing the origins of the Salieri crime family in 1900s Sicily. Unlike standard sandboxes, it focuses on immersive storytelling with a gritty, hand-to-hand combat system and period-accurate weapons like bolt-action rifles and clubs. Word on the street is that this game was originally rumored as DLC for Mafia 4 but expanded into its own title, promising vehicle combat with early 20th-century carriages and "dirty" visceral brawling. If you crave organized crime with a Godfather sheen, this is it.

Looking for GTA but with infected hordes? Set in a post-pandemic America after a deadly outbreak, The Day Before blends survival mechanics with a massive open world. Scavenge for resources, team up with other players, and fight against infected monstrosities in a landscape reclaimed by nature. While the game had a controversial development history, the current 2026 version features revamped PvPvE zones, drivable vehicles, and detailed city environments that feel like a last-gen GTA Online meets The Last of Us.

For those who want freedom without the crime, Under the Waves by Parallel Studio offers a melancholic, beautiful open world beneath the North Sea. You play as a deep-sea diver experiencing strange phenomena while dealing with personal trauma. It won several awards for "Most Innovative Gameplay" at the 2024 Game Awards for its water physics and sonar-based navigation. It's a slow burn, perfect for players who want to explore every corner of a hand-crafted, eerie environment.

Developed by a team of former Rockstar and Ubisoft devs, this is the spiritual successor to Red Dead Redemption that nobody asked for but everyone loves. Set across a vast frontier with dynamic weather and an advanced NPC reputation system. Every wrong decision can turn an entire town against you. The game supports train robberies, duels, and a homestead system where you can build your own outlaw empire.

If you were disappointed by Cyberpunk 2077's launch, Nebula scratches that futuristic open-world itch. Flying vehicles, neon-lit towers, and seamless transitions from street-level brawls to orbital shootouts. The game runs on Unreal Engine 5 and features PS5 Pro enhancements, including full ray-tracing at 60fps. It's everything a sci-fi GTA should be—fast, dangerous, and aesthetically overwhelming. The storyline involves corporate espionage and cybernetic enhancements that genuinely change dialogue trees.

For the hardcore gamer who finds GTA too forgiving, Six Days in Fallujah is the definitive tactical shooter. Mapping urban warfare down to the literall street signs and building layouts, the game uses actual Marine Corps training materials to ensure authenticity. It's not an arcade experience—you will die from a single shot you didn't see. The AI is terrifyingly smart: insurgents will use flanking maneuvers, fake surrenders, and false retreats. If you want tension and decision-making over driving supercars, this is a must-play.

The sequel to the chaotic first-person hit, Atomic Heart 2 opens up the world even further. Glide across reactor fields, infiltrate sprawling underground training facilities, and fight biomechanical abominations. The open world is broken into "zones" that each feature unique ecosystems of enemies, from retro-futuristic security bots to mutated wildlife. The glove-based combat skills have been expanded with full elemental combos, making this the weirdest, most ambitious open-world shooter on the market.

While not a traditional GTA clone, Helldivers III introduces a "dynamic galactic campaign" that feels like a living world. Choose your battles on a rotating star map, with each victory or loss changing the war's trajectory. The drop-in/drop-out co-op introduces new vehicles, environmental hazards, and an enemy faction that evolves based on how players fight them. It's pure chaotic fun and the best way to play with friends.

The long-awaited sequel finally allows operators to use the "unidad" system against the cartel, turning the region into a rolling warzone. The map is reportedly 1.5x the size of the first game and includes cross-border missions into fictional neighboring countries. Vehicle customizations are back, with new drone warfare and night-vision stealth mechanics that force you to strategize rather than guns-blaze. It's GTA for the paramilitary enthusiast.

Rounding out the list is S.T.A.L.K.E.R. 2, a punishing open-world survival game set in the Chernobyl Exclusion Zone. The A-Life 2.0 system means NPCs and mutants live their own lives, creating unscripted emergent narratives. The game requires you to manage radiation, hunger, bleeding, and carry weight. There are no maps markers for most secrets; you need to explore, listen, and survive. It's the anti-GTA: slow, brutal, and atmospheric, but deeply immersive for patient gamers.
