It’s just a promo, but Marvel has produced three short CGI clips that merge together into a five-minute short that features Iron Man teaming up with Spider-Man and The Hulk to fight giant robots of mysterious origin.

Marvel threw this short CGI piece together to promote their comic lines, but the CGI is surprisingly well done. The whole thing gives us hope that these three characters will find each other on screen someday (probably not until Sony gives up Spider-Man to the greater continuity good).

Also, just the brief part featuring The Hulk makes us wonder why the character seems so impossible to handle when someone besides Marvel is doing it.

Anyway, we have the video below the jump, and we’re enjoying the shit out of it.
