From Black Cat and Green Goblin, to Venom and Doc Ock - each can be brought into battle with Spidey one at a time. Each character has an assortment of combos to deliver via the jump, attack and web/grapple buttons. There's also plenty of generic tokens and whatnot, to collect that build up your character's abilities as well as Spider-boy's own attributes. But outside of co-op, your partner tends to just get in the way, snagging your stuff and inadvertently blocking your attacks. Friend. Foe. Whatever. The only reason to waste your resources leveling up anyone but Spidey would only be out of sheer fanboy devotion.
Again, Spider-Man: FoF seems developed specifically with children in mind. The game is disturbingly dumbed-down at times, and the strikingly bland levels would feel right at at home in an early Crash Bandicoot title. And that's not to mention the lack of polish. The fixed camera tends to obscure you, and you can actually move completely out of frame. C'mon developers! With three dimensions comes camera customability (reference #2 - One more!) The game could've compensated with a decent targeting system, which it sadly doesn't.
For adult Spider-Man fans (We are many!) the game is downright obnoxious. It makes a remarkable team-up of comic book history feel like a fluffy pilot for Marvel Babies. After defeating every repetitive barrage of enemies, you'll be consistently graced, again and again, with an extremely obvious opening door animation, whose sole purpose appears to be so the characters can deliver a hackneyed "Here we go again" line of cringe-inducing dialogue. The only thing keeping Spidey from saying something as cliched as "I'm getting too old for this shit," is that he's voiced by an actor who sounds 11 years-old.
