Final area
First, step into the power chamber in the middle of the vault of ages. Because there is only a limited amount of time you have to use the harmonic powers, choose a faster character to do this. There is a yellow meter that will show you how much harmonic power time you have remaining. Go straight up or straight down to reach the generators. The downward path has a small maze in it. Go right instead of left. At the generator, Apocalypse is waiting. You must beat him up before you can destroy the generator. Destroy the generator and repeat the same process with the other one. It does not have a maze, and it will be a straight shot directly to it. Just like before, Apocalypse is waiting for you at the generator. After destroying the power of the harmonic machine, he will bring statues of the horsemen to life. You must focus your attacks on the horsemen and get them out of the way before tackling Apocalypse. When you kill the horsemen, they will return to statue form. Then, kill Apocalypse twice to complete the game. Note: Make sure you have a full load of health and energy packs before attempting this.
Easy items
In Act 2 after you rescue Beast on Mikhails Warship, Blink will open a portal back to Avalon. Go through the portal to Avalon then immediately return to the warship. The scene of rescuing Beast will play again, and the ship is undamaged. You can go back and get all the items again. Repeat this as many times as desired.
To get easy Techbits, health packs ,energy packs, and items, return to the top of Apocalypse's tower where you fight Archangel. Smash all of the containers to get random free items. Repeat this as many times as desired.
Have Gambit and Toad on your team. Have Gambit use Prince of Thieves, and Toad use Plunder (this requires at least two extreme points). Do this when near a weapons cache and you can get about five times the amount of what you would normally get. This includes health/energy packs, and Techbits, but you still only get one special item.
Easy experience
For easy leveling up, go to the Holding pen level. There is a location where enemies keep teleporting onto the screen. It is just before the last area entrance. Note: If you stay too long without saving, your game will freeze.
Note: You need Magneto with Magnetic Grasp, a lot of energy potions, and the "Death Touch" cheat. In Act 4, go to the holding cells. If you came in from the sewer, go up from the sewer entrance and take a right into the first room. If you came from the stockade, go up from the stockade entrance, take a left, and go through the next few rooms. Both ways should lead you into a room with two spawners and a scanner-like platform. Run through the scanner and it will "scan you". After this, enemies should start spawning. Have the player controlling Magneto run onto a spawner and constantly use Magnetic Grasp. Enemies that spawn on your spawner will be instantly killed and they will fly from the other spawner and die as well. If you have the "God Mode" cheat enabled, this will level you up indefinitely until the level cap. If you use potions, you will only be able to level up while Magneto has energy.
