X-Buster with Beam Sabre as final charge level

If you do the following, a green charge level will replace the red charge level of the X-Buster, which fires 2 charged shots and a beam sabre shot. The Beam Sabre will take away half of any given boss's health, including the Sigmas.

During the second stage of the Doppler fortress, switch to Zero. There is one gate that he can pass through: the one that leads to the mini-boss fight with the "bug." If Zero defeats the bug, it will fall on him and explode. X will teleport in, and Zero will pass the Beam Sabre to X before he dies. Note that this means that you cannot use Zero again, since he's dead.

Golden Armor

First, collect all of the Heart Tanks, Sub-Tanks, Ride Armors, and Armor parts, but DO NOT take one of the enhancement chips offered by the pink capsules. Head to Doppler Stage 1, and make sure you have full energy (use the Ride Armor if you think you won't be able to keep full energy). Somewhere in the stage, there will be some balls with spikes falling into a pit. Jump to the left side of the pit and you will go inside a secret room. Inside this room is a capsule that contains the Gold Armor. Like its name, this armor will turn X's suit a golden color, and it also gives him the abilities of all four enhancement chips.

Secret Golden Chip

Note: For this to work, you need all power-ups BESIDES the chips, and have full health. Go to the First stage of Dr.Doppler's Lab. Near the end, you should see a bunch of spiked balls falling into a pit. Jump and cling onto the left side of the pit and you should slide into a secret room, which contains the upgrade capsule for the golden chip. This chip gives you all the benefits from all the chips, and turns Mega Man's suit into a golden color.

Obtain Zero's Z-Sabre for Mega Man...

1) After defeating the first two mavericks, you will now be able to access Vile's mini stage through the funny looking teleporter in the Volt Catfish, Crush Crawfish, or Blizzard Buffalo stages. Go there. You MUST defeat Vile with either Crush Crawfish's or Neon Tiger's weapon, and then quickly make your way out of the stage before the timer reaches zero. This trick will not work if you do not follow this step.

2) Complete the rest of the stages. Although it is not required, you should find all of the Upgrades, E-Tanks, Heart Tanks, and Robot Armor pieces. Make it all the way to Doppler Fortress Level 2. If you completed Step 1 correctly, this level should be alot harder now, as the stage will be filled with water and different enemies.

3) Right before the first sub-boss door, switch to Zero. Go inside, and defeat the bug robot. He's not too difficult...stay toward the center, then when he comes towards you, dash under him, and he should land on the ground behind you, then shoot him. After you defeat the bug robot, it will land on Zero, damaging him badly. At this point, he will give Mega Man his Z-Sabre to use for the rest of the game. Use the Z-Sabre by charging the Y button all the way up to the fifth energy level(green) and then firing.

Hidden MMX Bosses

Just at the start of the level Frost Walrus, you see Blizzard Buffalo from MMX3 trapped in ice in the background. When you fight the mini-boss leading to Area 2, you will see Chill Penguin from MMX1. Like Frost Walrus, they are both ice related.
