Even though I have cleared the entire map & destroyed all the computers necessary to get prestige, I still can't open the exit door with Bullet. They just say "we need both keys to unlock this exit". And I have the both keys as I KO'd all enemies, including the two generals...
Is this a familiar bug to anyone else? Seems like I'll be starting the mission all over.
EDIT: Problem solved by restarting the mission... Duh.
