I'm a little surprised to have not seen a thread about this soon to be released game from developer Almost Human. I first read about it some time ago on RPS and have been following it's development ever since. It's billed as being an old school dungeon crawler and brings back massive nostalgia from Eye of the Beholder (1991), which is listed as an inspiration along with Dungeon Master and Ultima Underworld. Further information and screen shots are available from the developers site, Legend of Grimrock.
The game isn't out yet so I can't make any comment as to how it plays, release date is April 11th. It will be available from Steam, GOG.com or the developers site Legend of Grimrock. Pre-order price is $11.99, which represents a 20% of full price ($14.99)
RPS has done a Wot I Think and Totalbiscuit a WTF is.... From all accounts the reviews are positive thus far, I've avoided them for the time being so as not to spoil my trip down memory lane.
