• Heart Tank:Climb up the wall before the first gate. (The wall with the green water falling down it.)
• Kangaroo Robot:You need the Frog walker. (Any others will short out when you take them into the water.) Use the walker to reach the giant fans to the right of the underwater area (you can destroy them if you want), then jump up to the surface. Head left, jumping across the water (and Air Dashing over the turtle shells if necessary), to reach the K part. Alternately try destroying the fans and charging up the Frost Shield while underwater.
• Super Boots: This pink capsule is only accessible with the Frog walker. Go past the fans and to the surface again, and head right.

Tunnel Rhino

• Heart Tank: Use a powered-up Triad Thunder blast to knock down one of the boulders you come to (the ones that are strapped to the ceiling and that reflect all your shots).
• Sub Tank: This one's a piece of cake. It's right out in plain view at the top of a tunnel, as long as you go far enough to the right.
• Helmet: This is behind the other boulder. Since you need both the X-Buster enhancement as well as the Triad Thunder weapon, don't count on getting it right away!

• Heart Tank: You need the Air Dash to get this one...it's over a bed of spikes. Ride the second lift all the way up instead of jumping off at the first tunnel you come to.
• Sub-Tank: You'll need a Ride Armor to snag this item. Head right from the walker platform, and simply fall down the tunnel. Your walker will crash right through the floor when it reaches the bottom.
• Armor: You will find a spike-lined vertical tunnel with a strange device at the bottom. To get the device to lift you to the capsule, use a powered-up Gravity Well to reverse gravity.

• Heart Tank: It's through a wall on the right side of the vertical tunnel where the mace robot falls through. You need a Ride Armor to break in.
• Hawk robot changer: Use a powered-up Triad Thunder shot to blast through the small gray platform near the beginning of the stage. It's a few blocks to the right of the Ride Armor platform.
• Super Armor: There is a tunnel in the floor that looks like a bottomless pit, but is actually more of the level. Drop down in a Ride Armor, and use the walker to bust the wall down there.

• Heart Tank: Climb the wall at the end of the stage (before going through the gates that lead to the Maverick).
• Sub-Tank: It's on the right side of the big room full of mace robots and insects. You can either use the Air Dash or hitch a ride on one of the insects.
• Hyper Buster:  You need the Tornado Fang to drill through a wall. Look for a wall with cracks (your normal arm cannon shots will bounce off. This is usually a big clue that the wall can be broken).

• Heart Tank: This is behind some blocks that cannot be broken. However, after some time, they will go away. I think the trigger is defeating Blast Hornet.
• Frog robot changer: The Air Dash is about the only way to reach it. It's high on the left wall once you climb outside.
• Hyper Cannon: This is the super enhancement for the X buster. Get it by utilizing a Ride Armor to break through some blocks. (Again, your shots will bounce off.)

• Heart Tank: It's to the right of the huge open area. You need the Air Dash.
• Chimera Ride Armor (N): This is the critical piece, for you need this one before you can use any of the others. However, you need the Tornado Fang to get there. When you are crossing the garages, blast all the blocks and a hole will be produced in one of the ledges. Drop down and break into one of the garages to find the walker.
• Super Helmet: You have to do a dash-jump with a Ride Armor (preferably not the Frog one!) over a big pit. You'll know the area when you see it.

• Heart Tank: You need a Ride Armor to break through the big blue ice blocks. The manual shows a picture of this.
• Sub-Tank: You need the Air Dash to get this. It's on the left side of the room where you find the Air Dash.
• Air Dash Boots: When you get to where snow is falling, stay up! If you can do this, you can make a big dash-jump off the third platform, and grab onto the ledge protruding from the wall. Jump up and head into the tunnel.

- One of my secrets -

X with Zero's Beam Sabre

  It turns out there is one door through which Zero can pass: the one that leads to the battle with the "bug"--the mini-boss of the second station of Doppler's fortress. If you have Zero defeat this bug, it will fall on him and explode, seriously damaging him. X will teleport in, and since Zero is too damaged to fight, he will pass off his Beam Sabre to X. (This means, of course, that in order to get the Sabre you must forfeit Zero--and this means you'll end up with what I consider to be the worst of the two possible endings.) The Beam Sabre is a powerful weapon, however; it will axe away half of the energy meter of any of the bosses--including Sigma and Kaiser Sigma!
