....into the strip.I need to go see Mr. House so i can start the final part of the game,but every time i go to the door and open to enter,my screen goes black.does anyone else have this problem?what in the world can i do?am i stuck and have to start completly over?

this game is so full of bugs it should have came with a can of Raid.

Go to Camp McCarran and take the monorail.

Maybe there's a dialogue animation that's trying to trigger but can't? I've never had that same problem (though once, it just sat at the loading screen for 10 minutes before I had to restart the PS3).

There's also that weird "Old Cowboy Hat" trick/glitch. Is it that?

what is the "Old Cowboy Hat" trick/glitch?

Try the other entrances, maybe?

As far as I'm aware the Sewers (Which i thought could take you too the strip :c) don't work as I thought they would..

And there are no other entrances other than the Monorail and the Gate..
I think.
