Sabotage

Stark Enterprises has unleashed the Infinite Engine, which promises to be an energy source unlike anything ever seen before. But saboteurs from both A.I.M. and Hydra have set their sights on the engine as well--along with Dr. Doom. When a respected scientist is killed and the Engine taken over, Spiderman and Iron Man join forces to safeguard the Infinite Engine--and all of humanity.
