On ALCATRAZ you need to do the find 5 cells keys goal.

Then go through the portal by the lighthouse (yuo'll end up on the roof) now turn right and do the slide the swithch goal which is in front of you when you come up onto the roof.

When you've done this a trap door will open go down it and there will be a stat point and about 3 more goals.....

In the Sanfrinsico level go to Chad Muska.

There is a very long rail goin up the stairs.

Get enough speed to grind up the steps.

Then you`ll see an elevator. Go in there and you`ll find 100$.

Hidden tape 4th level:
To get the hidden tape you need to get
lots of speed befor you can do this.
Go to the house which has got a gap
between the midle get on to there.
once you get up wall ride and then grind on the right hand side.
When you grind get as close to the edge
then jump to get the hidden tape.
