Iron Man/X-O Manowar is a 2.5D side-scrolling action game where players can either control either Marvel Comics' Iron Man or X-O Manowar, originally owned by Valiant Comics (though in 1996 Acclaim Entertainment had bought out the Valiant brand and were distributing X-O Manowar comics under a "Acclaim Comics" label). Most characters and objects in the game are represented with 2D pre-rendered sprites, while backgrounds are made of simple textured polygons.
Version differences
The Saturn and PlayStation versions were released simultaneously and are largely identical, however the Saturn version features lower quality full motion video and uses lower resolution textures in places.
History
Title
Like several of Acclaim's published games, the title can cause some issues - the forward slash symbol is not present in any western Sega packaging (leading it to be called Iron Man X-O Manowar or by some, Iron Man and X-O Manowar). It actually derives from the PlayStation packaging's spine and thus may not be strictly accurate for Sega versions of the game. Similar issues are encountered with Spider-Man and Venom: Maximum Carnage and Venom - Spider-Man: Separation Anxiety.
