Dungeon Master and Eye of the Beholder were like mother's milk to me, and Legend of Grimrock is like a perfectly muddled gin and tonic. Grimrock's sequel now has a release date, October 15th, and a new trailer to coincide with the announcement. It shows a variety of enemies and areas, including what appears to be a cannon-wielding pirat(e), as can be seen above. There are also spikes and tile-based puzzles, as the dungeon gods demand.
I remember loading up Dungeon Master II and being amazed that there were outdoor areas. Monsters aside, the original's visuals were practically greyscale, so dark and dingy were the dungeon corridors. Eye of the Beholder II introduced areas beyond the corridors as well, which makes Grimrock's trip into the great outdoors seem like part of a dungeon crawling tradition. All grown up and heading into the big wide world.
Grimrock's island looks like a good place to go adventuring. Games need more islands - natural boundaries, the possibility of glittering blue seas, indigenous wildlife. They are the natural home of Proteus and Far Cry alike.
