I can't get the missile launcher room door to open. I talked to the soldiers on the observation deck. When I use the gameshark to walkthru walls the thingy that you help push over is in place and I can't get any further. I accidentally erased my other saved game where I forgot to draw Leviathan from Norg. I've restarted like 4 times. I can't get pasted this glitch.

You have to return to the room to the right of the save point. Go in there and instruct the soldiers to go to the circuit room (these soldiers will be by a full-life draw point). After this go back to the room that was gaurded by the soldiers and you can now enter.
