Developer Almost Human has hailed the success of role-playing game Legend of Grimrock and announced it has sold over 600,000 copies.

"We would've been happy with just one tenth of the sales numbers, so needless to say we're very happy and the future of our company is secured for a long time," the Finnish developer wrote in a blog update reflecting on 2012.

"Last year was an incredible success for Almost Human," it began.

"We released our first game, Legend of Grimrock, which was the best seller for two weeks in Steam and has continued to surpass our expectations. LoG reached 82 points in Metascore declaring it officially to be a great game (but we already knew that, right?).

"We also released the Dungeon Editor that has spawned lots of brilliant mods and Steam's Legend of Grimrock Workshop has over 450 entries already! Our great community is always surprising us with their skills, creativity and activity in the forums with 50,000 posts and counting. And those post are really high quality stuff too, unlike most forums dedicated to games. That means you don't run out of dungeons to explore in the future.

"Towards the end of the year we also released the highly anticipated Mac and Linux versions of LoG with great new features and optimisations."

Now, thoughts turn to the future. Almost Human stopped short of announcing its next game, but did share two screenshots, below, to tease a new project.

"We thought we could share with you a glimpse of some new exiting things we've been working on. But beware, this is only the tip of the iceberg. Enjoy!"
