The Playstation version of Marvel Super Heroes was released in 1997. This marked the first time a Marvel by Capcom game was released for the Playstation, as X-Men Children of the Atom wasn't released on the PS until 1998.
Unfortunately it showed what was to come of all of Capcom's arcade conversions to this system. This version is slow -very slow. There is lots of slowdown, and using the larger characters can make the game become almost like a slide show. Certain attacks also make the game lose speed, such as Magneto's EM disrupter. Lots of animation has also been cut out, making things very choppy.
The Playstation version was the worst of two bad versions available in 1997 -the SEGA Saturn port wasn't great either. If you want to play this game on a console, go for the Saturn version.
