Legend of Grimrock is getting a big expansion soon, and eager gamers can play the public beta starting today. Developer Almost Human plans to release the dungeon editor expansion as a free update to the indie RPG in the future, allowing would-be modders to craft their very own dungeons from scratch, complete with custom challenges and objectives. It's certainly a neat concept, and you now have your chance to try it out ahead of schedule.

According to Almost Human, the update will bring along with it an "intuitive graphical interface, instant in-editor preview, comprehensive modding capabilities," and even built-in Steam Workshop support. 

In order to preview the beta, you simply need to own the game and have it installed on your computer via Steam. From the menu, you can boot the beta up and try your hand at crafting devious dungeons all your own.

Not sure if the game is for you? No problem. An official trailer for the dungeon editor expansion lies in the dank dungeons below.
