Foundation Multilplayer Map (w/ Glitch):
Unlock the hidden Foundation level by completing the single player campaign on any difficulty. Due to a serious glitch in the game (and one that will not be corrected), you will need to do the following to unlock the Foundation map for a specific profile:
1. Start a co-op game with a profile with access to the last episode (The Great Journey) and a completely fresh profile (i.e., one that has not even started the campaign game).
2. Fight to through the last episode until the players need to board Banshees to progress.
3. Have the new profile player perform a barrel roll (both directions) and a Loop-the-loop (stick down and A button).
4. Complete the game as usual and the new profile will have access to the Foundation Map. Since profiles may be renamed, you can delete your old profile and rename your new profile w/ the new map.
Difficulty: Legendary Level: Gravemind Word: Anger Effect: ??????? Fight all the way through the Covenant city until you reach the outdoors. As soon as you are outside, stick to the right-hand side and walk along the wall. You should see a Covenant wall thingy with a red rail on it. Jump up to it (crouch jump helps) and at the end there is the Anger skull in a small grav-lift.
Effect: All enemies in game are permanently cloaked, AI cannot see them and so are no help at all.
Just after you get off the gondola, and go in the structure, there is a big block of stone, jump on that an you can get on a ledge that leads out to the Covenant turrets, facing back towards the structure, jump up another level around the right side of the structure, It is pretty straight lined from here. You should find the Skull on a ledge when you make it around. No visible change to the HUD, BUT all enemies become invisible.
Black Eye Skull:
Level: Great Journey
Word: Black Eye
Effect: Shield won?t regenerate, when you melee someone you get energy power back, so if you melee someone you get a little bit of shield. So you can get a bit at a time all the way to overshield!
SGT Johnson will pilot the scarab and shoot at a building I am calling the Control Tower. If you take a banshee to the tower you will notice that, aside from where spires jut out of it, it has a round slope all the way around. If you take the banshee right up to the slope and as high as you can go, you can almost get over it. Here you must jump out of your banshee to land on the less steep part of the slope. If you turn your banshee to the side or all the way around, it may make it easier to land on the less steep part. Also, try to have your banshee land on a platform below, so you can use it to get back. Once you are on the slope, climb the rest of the way up it. If you are on the right of the door, then you have to jump onto the ledge next to the main part of the building, and then walk up a steep part in the direction of the door. Walk up that, then around and down on the other side. On this side (left of the door from scarab
