Zero's Slash combo
Press Square(2), Back, Square for a 4-hit combo which works on any Boss.
Alternate second half
If you let the colony collide with the Earth (let all the time run out), an intermission scene where Zero is infected with the Sigma virus and becomes a powerful Maverick will appear. For the rest of the game you cannot choose Zero and the dialogue changes for a few of the intermission scenes. Also, Zero fights more aggressively and uses different attacks when you fight him in the third Maverick level.
Destroying the colony
To destroy the colony, get it as close as possible with at least 3 parts -- i.e. the lower the hours, the better the chance of destroying the colony with the Enigma.
Megaman X4 appearance
Start a training level with X or Zero. Get to the end of the level to find Magma Dragoon, a maverick from Megaman X4. Also, make it to Maverick Base level 3. Play this level as Zero to fight X, who will use moves from Megaman X4 such as Soul Body, Frost Tower, and Double Cyclone.
Ultimate Armor for X or Zero
Go past all of the spike traps in the third Sigma level. You will reach what appears to be a pit. Slide down the right side of it until you fall into a room that contains a capsule. Step into the capsule to obtain the armor. When playing as X, you will have to intentionally die and restart the level to use it. Zero will automatically equip it.
Get all armors for X and Zero
Start the game with X and make sure you have the Fourth Armor. After destroying the colony (make sure Zero does not become Maverick), go to the third Maverick stage with either X or Zero. After getting the armor, die constantly and go to stage selection screen when the game ends. Then, go to the stage again, but with the other hunter. For example, if you went with Zero first, then go with X next or vice versa. Look at the left side of the stage selection screen to find the Fourth Armor, Black Zero, Ultimate Armor, Gaea Armor (if you have it), and Falcon Armor (if you have it).
