Metroid Prime 2: Echoes

You need to be an extremely good player to beat the game with the dark suit, but there IS a way to pass it up, as well as nearly the entire Agon Wastes segment of the game. You can move on to Torvus Bog as soon as you get your translator updated for amber holograms and acquire the space jump boots. The developers for the game put a failsafe in the Abandoned Base in Dark Aether. That is, your energy drains a lot faster in that room unless you have the dark suit. However, there is a shortcut in this room that will allow you to reach the portal within seconds of entering the room.

Once you enter the Abandoned Base, strafe along the right side of the room. Just before the ingclaw, there are two flat rocks up against the right wall with a small crack between them. Jump in this crack to get a small vertical boost that will propel you just high enough to space jump onto the platform with the portal. From here, you can enter Torvus Bog and continue with the game.

All you guys have to do here, is beat a couple bosses to recieve these multiplayer levels.
