Eye of the Beholder Steps Off the Grid with BtD
Eye of the Beholder is getting a rather unusual second life. BtD, an experimental engine created by Moon Bunny, reimplements the 1991 dungeon crawler as a true 3D first-person experience with smooth, continuous movement instead of the original game's grid-based steps and 90-degree turns.
This isn't simply a remake with prettier graphics. BtD reads the original DOS Eye of the Beholder data files, retaining the game's dungeons, puzzles, scripts and underlying content while interpreting them inside a modern Unity-based engine. No original game assets are distributed with the project, so you'll need a legitimate DOS copy of Eye of the Beholder to use it.
The developer says considerable effort has gone into keeping the original logic intact, including writing a virtual machine capable of processing the game's original level scripts. Enemies have received some modernisation too, including pathfinding better suited to unrestricted 3D movement.
BtD originally entered open beta in May 2026, and the project has recently started attracting fresh attention after footage of it resurfaced online. If you've ever wondered what Eye of the Beholder might have felt like had Westwood's dungeon been freed from its invisible grid, this is probably about as close as we're going to get.
