The player must alternate between flying through corridors to defeat bosses posted at the ends and possibly obtain new labyrinth keys, and exploring the labyrinth to obtain new power-ups and locate more corridors to clear.
Corridors[edit | edit source]
The corridors are air combat areas, where the Guardian transforms into a space craft. In total, the game has 22 corridors to clear. The game begins by having the player fly through the entrance: Corridor 0. When the boss is defeated, the player will arrive in the center of the labyrinth, in a section known as Area 0. From here the player can access the first real Corridor of the game, Corridor 1 and Area 1.
All areas of the game (except Area 0) have two corridors for the player to clear. In each area, there are corridors n and n + 10. For example, Area 2 contains Corridor 2 and Corridor 12. Corridors numbered 11 through 20 are secondary corridors and not required to complete the game, however, by completing them, the player can obtain useful power-ups to proceed more easily. These corridors are also always immediately accessible and are generally easier to face. Corridors 1 through 10, on the other hand, are the primary corridors and are required to complete the game. Each is locked and usually a little more difficult, but these are also the corridors where the keys are hidden. To unlock these primary corridors, the player must find a hint somewhere in the area that reveals the secret to unlocking the gate. Two of the hints are found in Area 0 rather than their respective areas. The following are the procedures for unlocking each corridor:
- CORRIDOR 1: Shoot the blue hatch of the corridor with your main weapon for a few seconds.
- CORRIDOR 2: Touch the four panels at the corners of the blue hatch to make them explode.
- CORRIDOR 3: Wait in the entrance room of the corridor, after a while the entrance will open automatically.
- CORRIDOR 4: Enter and exit several times from one of the rooms of a round creature that has already sold you an item. Eventually the creature will tell you that it has removed the seal of corridor No.4, which will become accessible.
- CORRIDOR 5: Shoot the "Corridor 5" sign above for a few seconds.
- CORRIDOR 6: Use any special weapon in the entrance room.
- CORRIDOR 7: Enter and exit the entrance room of the corridor several times. Eventually the hatch will open.
- CORRIDOR 8: Set your optional weapon to NO USE and press the A button
- CORRIDOR 9: Simply stand on the blue access hatch.
- CORRIDOR 10: Keep firing for a few seconds, in the access room.
Each time a corridor is cleared, a collectible power-up is left in front of the entrance. Once collected, the entrance to the corridor is permanently sealed. When all 10 primary corridors are complete, the exit corridor in Area 0, Corridor 21, appears for the player. After completing it, the player enters the final battle.
The Guardian Legend is fairly non-linear. You are not required to play through the areas in a particular sequence. However, only after completing the primary corridor of a given area, you will obtain the key needed to access the next one. To proceed more easily, it is also advisable to tackle all the secondary corridors in their numerical order and fully explore each area before moving on to the next one, in order to obtain all the available power-ups.
Labyrinth features[edit | edit source]
Blue Lander checkpoints[edit | edit source]
Throughout the game, you will find rooms that contain large Blue Landers who will speak with you. They offer to provide you with a password that will allow you to continue your game. To receive a password, you must set your special weapon selection to "NO USE" on the sub-screen, and press 
. However, you do not need to obtain a password to get the benefit of visiting these rooms. If the Guardian loses all of her health and dies in a corridor or in the labyrinth, and you choose to continue, you will continue from the last Blue Lander checkpoint that you visited. If you never visit a checkpoint, you will resume in the center of the labyrinth, where you appeared after completing Corridor 0. You will always return with all of your items and upgrades in tact.
Labyrinth blocks[edit | edit source]
Each room in the labyrinth may contain different blocks arranged throughout the room.
Blue pyramids serve as doors throughout the labyrinth. When shot, they leave behind a small black gate. If the black gate is empty, you are free to travel through the door. If the black gate contains a symbol, you must possess the key with the corresponding symbol in order to pass through.
Yellow pyramids are destructible objects that may be scattered throughout a room. They are destroyed with one shot, and unlike item capsules, never contain items. They will typically replace any unexplored item capsule if you leave a room and return.
A green pyramid is a door that is locked until you accomplish some task in the room. In a majority of cases, the task is usually to collect an item that is obtained by clearing a corridor, or defeating an area mini-boss. Once the item is collected, green pyramids will become breakable (either yellow to allow passage in a labyrinth room or blue to reveal the warp panels in a corridor room).
A red pyramid is simply an indestructible barrier designed to keep you to one side of a path or another. There is no way to remove them, and one portion of a path that they divide typically leads to a dead-end.
Upgrades[edit | edit source]
Upgrades are available throughout the game as you search for them throughout the labyrinth or by defeating mini-bosses and bosses.
Weapon upgrades are available around NAJU. The higher the upgrade, the more powerful and useful the weapon can be, but more chip consumption, requiring Red Landers to expand the chips. Weapons can be upgraded to Level 3.
If you have 5 Shields in your inventory (including your default 1 shield), your walking speed and ship speed in the labyrinth will increase.
Red Landers not only expand your chip count, but also improves your normal gun.
| Level | Chip Max | Notes |
|---|---|---|
| 0 (Start) | 50 | Normal Gun shoots 1 row; 3 MAX bullets per screen. |
| 1 | 100 | Normal Gun (above 100) shoots 3 rows; spreads 0.75 block wide; 12 MAX bullets per screen. |
| 2 | 150 | |
| 3 | 200 | Normal Gun (above 200) spreads 1.25 blocks wide. |
| 4 | 400 | |
| 5 | 800 | |
| 6 | 1200 | |
| 7 | 1600 | |
| 8 | 2400 | Normal Gun (above 2050) shoots 4 rows; spreads 2.5 blocks wide; 16 MAX Bullets per screen. |
| 9 | 4000 | MAXIMUM Chips for Normal game. |
| 10 | 6000 | MAXIMUM Chips ONLY for Corridor Rush Mode. |
You start the game with 8 Hit Points (8 bars on your energy gauge). You can increase this limit in two ways:

- Reach certain scores. You earn an extension at the following scores:
- 30,000
- 100,000
- 500,000
- 1,000,000
- 2,000,000
- 3,000,000
- 4,000,000

- 6,000,000
- 7,000,000
- 8,000,000
- 9,000,000
NOTE: Do not achieve a score above 9,999,999 or else the game will instantly softlock.
Tricks[edit | edit source]
Due to limitations of programming in the game, there are a few tips and tricks in the game:
- Your main gun can fire an additional bullet on screen if you set your sub-weapon to “No Use”.
- In the labyrinth, you can completely refill your Chips and Health by touching a red/blue orb from a diagonal location, provided there is an object blocking you.
- If you have the movement speed up (5 shields), you can walk through the indestructible pyramids by moving diagonally in between. This trick can be used against yellow pyramids and item capsules as well. You can only walk horizontally.
- If you have the Level 2 Fireball on Labyrinth Mode and have the movement speed up, you can create an invincible damaging forcefield by simply holding the direction that the Fireball is moving because the walk and fireball are both the same exact speed! Abuse this as much as possible before upgrading to Level 3 Fireball.
- If you have the Level 3 Fireball on Corridor Mode and have the movement speed up, you can create an invincible damaging forcefield by simply holding up while shooting the Fireball because the flight and fireball are both the same exact speed! Unlike the Labyrinth trick, this is less practical because by the time the invincibility ends, you are stuck on the top of the screen left wide open for attack. Also, you get the Fireball 3 very late in the game. This move is only effective against specific bosses and/or tough situations like mini-crystal or exploding blue plants chasing you.
- In shops with 3 items, there is a trick to allow you to buy all the items (provided you have enough Chips to do so). To do this trick, hold Start while collecting an item. Normally, collecting an item would make the other 2 items disappear, but with this trick, the 2 other items will not disappear. If you see a Red Lander, you should purchase it first before the other items to increase your Chip count. You can get weapon upgrades much earlier than usual with this trick.
