Enable the "X's Ultimate armor" code. Play through the first two introduction level, then
start the Jungle level. Go halfway down the second waterfall and go to the right. Enter
the capsule and to get the Ultimate Armor along with Nova Strike and the aerial attack.

Play as X and when you use the Jet Stingray attack, press Down whenever you want to make
it go down. When you press Down with the huge stingray attack (requires the plasma shot or
the other arm upgrade), it goes across the screen while shooting smaller attacks
vertically north and south. You can also shoot large boss attacks if you have a arm
upgrade (plasma or the other one).

To defeat Serges in the X-Hunter levels, use the G. Crush to destroy the four cannons,
then use the Sonic Slicer to damage Serges.

Use the Gala attack with the Ultimate Armor to have the best weapon that defeats most
Bosses, including Sigma (both rounds). Keep using that attack, which is unlimited. Be
careful with Sigma, as he keeps moving around.

In the Doppler level, where you must defeat all the Bosses, shoot the Beam Saber on the
standing object. Usually if you shoot on it, healing power-ups will appear. However, if
you shoot on it with the Beam Saber an extra life will appear.

Armor: Laser Institute. At one point in the level, you will see a laser activated door in
the floor. Direct the laser to it and open it. Inside will be a large system of lasers to
correct. Once finished. you will open another door in the floor. Drop down and go left
(you can go through the wall). Jump across the ledge beyond the wall to find the capsule.

Boots: Amazon area. After falling into the first cave you will notice a path behind a
Praying Mantis Maverick at the bottom of the drop.

Helmet: Central Museum. In one of the random totem pole areas.

X-buster: Weapons Center. After defeating the gigantic Maverick, a portal will appear.
Once inside the portal, go left instead of right.

If you let the colony collide with the Earth (let all the time run out), an intermission
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
intermissions. Also, Zero fights more aggressively and uses different attacks when you
fight him in the third Maverick level. To get this faster, launch the shuttle before you
have collected all the parts for it. This will also display an intermission where Zero
goes Maverick and gives you the ending where X's memory of Zero is wiped clean. What you
do with the Enigma does not matter.
