In order to play this mission Bond will have to get a Gold score on eleven of the twelve missions so far, or in the game period. Not too difficult, but this can be a pain and many people may not even realize that this mission is available until later in the game if they don't get them soon. Anyway, while this mission is not necessary, it is a fun little bloodbath.
Gold: N/APlatinum: N/A
Objective: Rescue Mya
When this mission first starts have Bond kill the guy that is in the room with him, then pick up the skeleton key by the door and kill the two guards that are in the hall. After the guards are dead have Bond drop his Q-Spider. Near the next doorway is a spider hole. Run the Q-Spider through this hall and, in the next room, blow it up near the explosive barrels before the enemy guard can step on it.
After the explosion Bond will be able to stand along the wall near the hole and shoot the enemies that come for him, which will make taking out the enemies much easier. Additionally, have Bond walk into the room and back every now and then to trigger more enemies. Facing them at this spot is much easier then in the middle of the room. After they are dead head through the door opposite the hole in the wall.
Continue through the next large room, killing the enemies along the way, until the next doorway. Once Bond is in the small hallway here he will simply need to take out the enemy waiting for him, and the ones that try to ambush him from behind, and head forward to the next door to end the mission.
