For this mission, Elpizo has his sights set on sabotage. He wants Zero to destroy a boss and a computer room in Antarctica that control the main defense systems of Neo Arcadia. By destroying both, it will weaken their defenses enough to carry out his operation.
This mission is actually the easiest of all four, because the boss is astonishingly easy. The area, on the other hand, can be a rough journey to get through. When Zero transfers to the Computer Zone, one of the operators will tell Zero there are four cooling systems that are linked to the main computer. You must destroy all four. Each one you miss results in a five point penalty at the end of the mission, and the more you destroy, the easier fighting the boss will be.
Computer Zone Entrance Path
The start of the path to the Computer Zone isn't very challenging, but it immediately brings you over to the first place with water in the game, and threeicebergs are floating on top. More than likely, you'll want to fall into the water. The icebergs tilt back and forth as you move on them, and they seriously impede your movement. You need to dash hard enough to jump across them. Get over to the third one here to break open a Cyber-Elf Box, or do it the cheap way and shoot it to get File:MMZ Nurse Elf Icon.PNG Cyber-Elf Ishilar.
The water can also prove to be a suprise. As always, water increases your momentum when you jump, but this can be a problem here, because the water is infested with schools of Jangyo. They swim through the water and occassionally leap out to jump over the icebergs in the water. These fish Mechaniloids are very easy to destroy, but the amount of them and their speed can cause some cheap damage to your health that you don't need. Don't make a run for it, because you won't have enough time to react. Destroy them before they can reach you, and climb out of the water on the other side. Destroy 5 for File:MMZ Animal Elf Icon.PNG Cyber-Elf Stickie.
Panel Cannons are lined up in a row to fire shots at you as soon as you cross beyond the first water pool. Just stay far enough away to avoid getting shot at and destroy them cautiously.
The next pool of water gets a lot scarier. This time, the danger of two pits of spikes resides on the floor of the pool. You can jump further in the water over them, take the path of four icebergs above which gets you a Z-Panel, or even abuse the invincibility period by taking hits from Jangyos, but you don't want to do that, do you?
Now, you have to get past a slew of Panel Cannons that await on the other side, but you have to climb up a large wall to get through the area. Just don't get spotted, and you can wipe them out before they can shoot back.
On the other side of the wall is the Computer Facility, and one more Panel Cannon just to give you ilk, but you can grab some E-Crystals right before entering the Computer Zone itself, right above the entrance on a narrow ledge.
Computer Zone
Now, you'll enter the main cooling systems of the Computer Zone the water obstacles are replaced with pipes venting off excess blasts of bonechilling air. Run over a vent at the wrong time, and you'll be frozen in your tracks and lose not health, but precious seconds of time mashing buttons to break free. The cold air has made the pipes freeze over, and that means more trouble getting across them.
Along with the obstacles are the annoying dangers of Ice Lifters, bulldozer Mechaniloids used to clear away ice without slipping on it in the process. They will charge right towards you on sight, and their heavy-duty ice plows act as shields. You'll have to jump behind them or use the Laser Shot to do some damage, but they're clever enough to back up and catch you of guard even then. Try not to get frozen, since you'll take a bad blow from the Ice Lifters if they ram you. Destroy 4 to get File:MMZ Animal Elf Icon.PNG Cyber-Elf Fubuffa, the dog Animal Elf. This Elf elimates the knockback effect you suffer ever time you get hit, which can keep you from suffering a fatal mistake in close-knit corners.
Ice Lifters up on the higher ledges even have ice blocks guarding them that they push into you. You'll have to break the ice before you can get to them, and they'll try to back away after you break through.
When you get past the first Ice Lifter with ice blocks, you'll find yourself in the crosshairs of Rollin' 22's, enemies reminiscent of Rolling Gabyoalls in the X series, only much more irritating. Rollin' 22's are always attached to pipes, and fire 3 rounds of shots from their two-sided barrels at you. Even if you're far away, they can flip upside-down and charge down the pipes to try and hit you as they flip back up. Stun them with Thunder-element attacks, or blast them quickly, since they don't hesitate to fight back. Destroy 4 for File:MMZ Animal Elf Icon.PNG Cyber-Elf Atti, the monkey Animal Elf. This Elf allows you to scale ladders twice as fast. This helps to dodge enemy attacks, or shave a few seconds off the time it takes to get through a mission.
The next few sections of the cooling room are filled with a mixture of all the aformentioned hazards: freezing pipes, Ice Lifters, and Rollin' 22's are abundant. Just be wary of running blindly through as you get deeper into the Computer Zone...
Cooling Systems: #1 and #2
Don't be too eager to dash through the slew of troublemaking hazards. Eventually, you'll come to a dropoff down the path with an Ice Lifter below. Down here is the first cooling reactor. Destroy it immediately.
Further down is another dropoff with a pool of water and some Jangyos, along with the second cooling system. When you reach the end of the hallway, you can swing over a pipe right before a shutter door to get some well-needed Life Energy, if you can.The slick ice on the pipe is too hard to climb.
Sub Boss: Golem Type I
As fate would have it, the Life Energy was there for a reason; you'll encounter the third kind of new Golem, Golem Type I. This Golem looks like a hulking ice cube, with supercooled ice blasters for arms. This Golem is a bit more devious when it comes to battle, making use of its mobility in a sloped room and pulling cheap shots when doing so. It attacks by waving its arms around, shooting icicle spheres, and spitting giant snowballs out from its mouth. However, Golem Type I is suprisingly easier to beat than its counterparts. Both of its attacks can be halted with the Fire Chip, and you can take down this oversized refrigerator with two hits from a charged Flame-attack by the Z-Saber, hopefully fast enough to keep it from utilizing its charge attack on you.
After beating Golem Type I, you'll get File:MMZ Hacker Elf Icon.PNG Cyber-Elf Hafmardo. This Elf can instantly half the HP of any boss in the game.
Further down the room Golem Type I was stationed in is Cyber Elf Box on a narrow ledge above the shutter. Bust it open to get File:MMZ Nurse Elf Icon.PNG Cyber-Elf Fuppie, one of the four Cyber-Elves that adds four more bars of health to your HP.
When you enter the next section of the Computer Zone, you'll find Pantheon Guardians if you haven't gone through the Power Room mission first.
