Howard The Duck started off as a cartoon, progressed to a pretty chronic film (which attracted a limp cult following) and then moved onto the Spectrum. And like the film, the game was projected to be a huge success but wasn't really at all. Howard, then, is a duck, but not a nice, chummy one like Donald or Daffy. He wields a Neutron Disintegrator and is a Quack Fu Master. Rather handy, that, as he's faced with the prospect of having to rescue some of his pals who've been stranded on an island by the Dark Overlord.
So, presumably Howard walks round shooting people? Well, yes he does, but for a change you get an overhead view and Howard's in a maze. There are pools of slime to jump over, rivers to cross with the aid of a jet pack, and plenty of things to collect. And after that there are Howard was various mini-games to complete before you get to take on the Dark Overlord. Its all very well programmed and everything, but not all that inspiring.
Howards was actually rather cool in his Marvel Comics days. Pity how things change, eh, Spec-chums?
