Zillion/Middle levels

The middle levels have red walls and harder drones. The enemies in this section move faster and can shoot upwards, making platforms above them unsafe. This section will also introduce you to the autogun turrets.

From the elevator, head to the right. Unless you need another ID card, the room to the left doesn't have anything you can get to right now. As soon as you enter the room to the right, drop down and begin firing to take care of the two Norsa drones that will pounce on you. This room is standard, with all the keycode canisters being accessible and a hard to see security sensor in the middle of the top platform. Don't bother turning off the laser barrier field until after you've input the room code, because the elevator appears behind it. When you're ready to leave, you can turn it off with. It pays to be good at jumping mines in the next room, because there are five of them on the way down to the bottom of the room, and you have to get by them while two drones are shooting up at you. Don't stop to get the canister on the way down, as all the keycode canisters are at the bottom, and it's more important that you get those drones first. You can go back up and get the ID card after you've taken of them, if you feel it's worth it trying to jump over whatever mines you didn't already blow.

The next room to the left contains the first auto-gun running along the ceiling. It fires infrequently, so the only trouble you may have is crawling over to the canister on the bottom left. If you really must, you can turn off the turret with. There are two ways out of this room, but head right to get Apple first. After an empty hallway you'll find another room with a drone in the entry. This room has autoguns going along the left wall and across the bottom of the top platform. It can get a little tricky, so use if you need them disabled for a short time. Both mines in this room can be destroyed with your level two Zillion as long as you can hit it just right while jumping. Head to the right when you've unlocked the barrier. This room is a little tricky since you're forced to go through a security sensor, and when you do the drones drop down right on your head. It will cost two ID cards to turn off the sensor and laser barrier with and, but it's probably worth it - especially if you're low on health.

After inputting the room code, take the elevator up. It's recommended that you get Apple now, if you can, because it wastes a lot of health and you'll be getting a level up soon. It is possible, after turning off the laser barrier with to stand on that tiny lip and jump to the elevator without falling into the security sensor. As soon as you get into the room above, jump up to the platform on the right to avoid the drones' lasers. You have to wait until the screen completely stops scrolling before attempting to jump. In this room, take out the mine and the drones then open up the barrier and head to the room on the right to rescue Apple. In this room there is a stationary autogun on the left wall and moving ones on the right wall and ceiling. It's a good idea to turn them off with as well as the laser barrier with. You have to collect the keycodes behind all these hazards to unlock the room code and then go back through them once the barrier's open, so expect to burn a few ID cards here. Remember that if you are using the invincibility cheat, you'll want to make sure JJ is selected when you exit the status menu, or you'll be stuck with Apple for the rest of the game or until you rescue Champ. When you're done, use Apple for a while if you're too low on health for JJ, and head back over to the room on the left and down one.

From this room take the exit out to the left. Out in the hall you'll need to lay down and shoot the wall to open it up. Once you're through, head to the top and go into the room on the left. This is a simple dodge-the-autogun room, but you can also turn them off with. If you're running low on health, you can take the left exit and shoot the hidden power up on the right side at the bottom of the elevator shaft. Just be careful of the drone right outside the room. When you get back, or if you don't need the power up, turn off the laser barriers with and take the elevator down.

In this room you'll be sandwiched between two drones, so just do your best to take them out quickly and limit the damage they do. There's an ID card up top and all four keycodes are in sections guarded by laser barriers and moving walkways. Unless you're a very poor jumper, you should be able to get away with just turning off the laser barriers with. On your way to the computer console you'll be running against the walkways, so just press and hold SMS 1 while pressing SMS Left (Dpad) at the very ends and you'll make it. When you're going the other way, after you've input the room code, just stand still and let the walkway move you. When you get to the end, press and hold SMS 1 and press SMS Right (Dpad) quickly at the end. When you're getting the keycodes, remember to get the canisters on the left first, so you're not wasting time going against the walkway while the lasers are off. If you really need to turn off the walkways, you can use.

The room below can go quite easily if you don't trip the sensor running along the bottom of the screen. When you first enter, jump to the platform to the left and get the canisters. When you have the keycodes, come back the same way across the platforms at the top. Start pressing SMS Right (Dpad) as soon as you drop down to the moving walkway so you don't get pushed over to the sensor. For the canister right next to the laser barrier, just note that you don't have to directly in front of it to get the keycode. It's up to you whether the ID card right next to it is worth tangling with the barrier or the sensor trying to get. When you've unlocked the room code, take the elevator down. No canisters to get in this room; just avoid the autoguns while crawling under the sensors on each level. In the bottom room you'll find three level two canisters and three laser barriers. Avoid the mines and head to the computer console to turn off the laser barriers with. This room is a jackpot room, with a floppy disk, a level up and a Zillion upgrade. When you've gotten everything, head back to the computer and type in the Warp A code to head back to the beginning elevator.

This route is recommended, as you can pick up a few level ups that you couldn't get before, and it bypasses trying to go back up the way you came. Head down the elevator and go over four rooms to the left, stopping in the third to break open the level three canister for a level up. In the fourth room, either take the elevator down and go to the room on the right, or take the left exit and take the hallway and elevator down to that room. In this room you'll be able to get over that wall on the right side of the room for another level up. When you've gotten it, head right until you can take an elevator down from a hallway. Take the elevator down, and this time head to the room on the left and get the level up at the bottom left corner to max out JJ. Keep in mind as you're going on now, that you can shoot out mines with your level three Zillion from the prone position. Head back out into the hallway, and go one room right, one room down and then all the way to the left until you get to the room with the level three canister to get another floppy disk. From here, head back out to the elevator two rooms to the left. At this point you cans skip the rest of the middle levels, because there's nothing else you need. If you've been using JJ the whole time, he's maxed out already, and you'll only be missing out on unneeded level ups and a scope.

Take the elevator up to the top again and head left into the room. Turn off the laser barriers with and go down a room. Deal with the drones here then go down another room. In the next room, don't even worry about tripping the sensor, because you can get out of the room to the left before the response drones can hurt you. Out in the hallway take the very long trip down to the bottom of the Norsa base. If you happen to be low on health, or just want to give Apple an upgrade, stop in at the first hallway to the right and grab a level up and a power up in the room there. Don't fall for the trick down the second hallway though. The canister is empty and it's a deathtrap in there. You are now in the lower levels of the Norsa base and in the last and biggest section.
