Spider-Man - The Movie - The game

[Eo]

I got this for X-mas, and it's pretty fun! But one thing...
I REALLY need tips for how to get past the thing where there's a bunch of thugs in the abandoned warehouse. (I know, I know... I didn't get very far, did I?) I once got past the locked door (with my sister's help) but then my health was already so low I died.
And as Spider-man said in my favorite Ultimate Spider-Man Comic:

"Guns! Why do you always have guns!? Y'know, some people say a gun is just a replacement for..."

*Gets shot at by about five people*

"...Or not."
