Best free "dungeon crawl" games

Dungeon crawling was the core objective in the very first CRPGs (Computer Role-Playing Games) to ever appear on computers. In those early days these titles felt like primitive roguelikes, focused almost entirely on navigating dark mazes and surviving whatever lurked within.
As PC technology advanced in the 1990s, dungeon crawlers evolved into something more visually striking. Developers used clever 2D graphics that simulated 3D environments, creating an illusion of depth that made the genre far more immersive and appealing to a wider audience. This was the golden age of dungeon crawlers, when some of the most legendary RPGs were born:

• Dungeon Master – the instant classic that sparked the 3D dungeon-crawling craze.
• Eye of the Beholder – the definitive dungeon crawler series of the 90s.
• Wizardry – more than just a dungeon crawl, it became one of the longest-running RPG franchises.
• Might and Magic – closer to an open world than most, yet still steeped in that dungeon-crawling spirit.

These games dominated gaming magazines of the era and cemented themselves as milestones of PC RPG history.

But the tide shifted in the early 90s. When Wolfenstein 3D—and later Doom—stunned the gaming world with true real-time 3D environments, the rules changed. CRPG developers began moving toward real-time, first-person experiences (see Ultima Underworld), abandoning the grid-based, turn-by-turn systems that defined traditional dungeon crawlers. The old 2D/3D hybrids soon began to lose their charm, making way for a new era of role-playing design.
