First of all, I would like to say that you're welcome. Instead of a video, I have provided a still image instead. A video preview of this game would make grown men cry, particularly because the animation is so god awful.
Fantastic Four (1997) was a side-scroller beat-em-up -- which sounds pretty great at first, but Acclaim made sure to dash those hopes by making this game. The animation is near comedic, as this was the time where developers thought 3D was better than anything they could do in 2D. So instead of having a sprite of the Thing throwing punches, the tied it to a very archaic 3D model and had him throw his fists like nobody had ever taught him how the human muscle system works. It featured terribly animated versions of the entire Fantastic Four team (and She-Hulk... for some reason) and could even be played in four-player co-op.
I remember renting this game as a child and getting stuck on the first boss. You literally can't seem to damage him. I wasted my entire week's rental trying to defeat him. I thought maybe it was just because I was young, but upon researching it for this article, I found a video of a person recording the game who also gives up on the boss and ends the video. Has anyone actually ever gotten to level two on this game?
