How do you beat Silver with Shadow in Sonic the Hedgehog

Just don't let him get close. When he picks stuff up to throw, attack him, then do something to get away. Also, if you are separated by a breakable crate on the train, you can homing attack the crate to make the parts fall forward and deal damage to Silver.

Here's another way:
NEVER let him get close, and absolutely DONT jump near him because if you are above him, he will send you flying straight up and he'll keep on catching you until you die. :(. Anyway, stay away from him and just jump on the breakable parts of the trains (they're red, I believe) so he will get hit by them when he destroys them. :D Good luck, if you haven't already beat him yet
