9	Each time you successfully put in the code, several waves of enemies will spawn. Sometimes, one of them will attempt to hack and prevent you from accessing the vault. Destroy them immediately.
10	After the third set of codes are put in, the vault will open and you can get your rewards within. Access the panel at the far end of the room to end the mission.
