Recently announced on Facebook by the creators of Dwarfs!? Is a new game called Quest for the Gauntlet, for Windows, Linux, and Mac systems. Although this is early footage, it looks to be a 4 player co-op in the same genre type as Gauntlet from the 1980's. They also look to be putting in an Assassin, Prince, Weapon Master and a Rune Master going by this drawing.
Personally I can't wait, as I remember playing the original Gauntlet in the arcades and for anyone that hasn't played Gauntlet, see the picture below, ahh good times :)
