Gamereactor have published an article on the development of the new Gauntlet:
"Add more tingle" reads a post-it note on game designer Emil Englund's desk. He's currently showing us how the Lich mini-boss we just played in the demo is being redesigned. He's now equipped with a beam attack and his teleportation will target the character furthest away in the group (typically your Elf or Wizard). The beam and the teleportation are designed to add more tingle. Emil Englund illustrates what he means by edging forward on his office chair as he says: "It's when you go 'oh shit! oh shit! oh shit!' because that beam is turning towards you or he teleports and drops on top of you." We all know the feeling, and when you think about it, it does tend to provoke a tingling sensation down there."
