I won this game with Michael and Wendy but Michael is the only one who can open the grating at the porch. Now I am playing it with Razor and Bernard and none of them can open the grating. As well none of them can open the garage. I get the message I can't budge it or it's rusted shut.
Take your characters up to the top floor, and use Hunk-O-Matic (body building) machine a few times. Then they are strong enough to open the grate. :)
THANK YOU!!
