Basic Play
Due to an unfortunate incident that occurred one year ago, the large cargo station, "OHME" was abandoned.
Motivated by the rumor that there is great treasure on board, you take on the challenge
as a "DEBUGGER" to recover the treasure and return from a place no one has ever come back from alive!
"LEON" and a rookie "DEBUGGER" (main character) enter "OHME" to investigate and unravel its mystery.
Players must explore "OHME" and make it to the lowest level ("LEVEL 6") within the time limit to take control of the sub-computer and stop the self-destruct.
You must defeat all of the enemies in one level to gain access to the next lower one.
You'll have to rely on your Sensors' sound and color changes to find all of the monsters.

BATTERY
You begin the game with two Batteries. Their power level will decrease as you use Energy Weapons and are hit by monsters.
You will start over from the Computer Room when the power level of the Battery you are currently using reaches 0, regardless of whether or not your other Battery has energy remaining.
Your Battery will not automatically switch over to the other, so when there is little power left, use a "BATTERY ROOM" to recharge or switch Batteries at "BATTERY SELECT".
Sensors
The Color Sensor reacts when enemies are close by. The type of monsters that the Sound Sensor will react to will change according to its version.
The Color Sensor will flash from blue to yellow and then to red as enemies draw closer.
The Sound Sensor will confirm an enemy's position by the direction of the sound it makes. A siren will ring when the enemy is close.
(It's easier to hear this sound when playing with headphones)
A Side Alert or Back Alert will flash when an enemy is approaching from the left/right or rear.
Alert Signal
When a monster breaks into the "CORE BLOCK" the word "ALERT" will be displayed.
If they are wandering around the passageways, it will be displayed in yellow.
If they are in the blocks, it will be displayed in red.
"LEON" will contact you when monsters break into blocks.
You can also confirm which blocks have been invaded by checking the "MAP COMMAND" and viewing which block points are displayed in red.
There are six levels to the large cargo station, "OHME".
It's made up of a central "CORE BLOCK" and an exterior "CARGO BLOCK" (Monsters appear in these blocks).
You'll need to go to the "CARGO BLOCK" to defeat all of the monsters in each level.
CORE BLOCK
The "CORE BLOCK" is made up of a central computer room (where "LEON" stays) and 8 blocks (A-H).
This is where you will find important blocks that allow for Battery recharge and lighting control.
As monsters invade the blocks, the points assigned to each block will decrease. Be careful as lost points cannot be recovered
When the number of points reaches 0, "OHME'S" computer will consider that block dangerous and it will break apart.
It will be difficult to explore areas if important blocks are lost.
Therefore, when the Alert Signal sounds you'll need to hurry to the invaded areas and drive back the enemy.
Important Areas
| B Block LIGHT CONTROL ROOM |
Controls the station's lighting. If you lose this room, all passageways will become dark. |
|---|---|
| C Block BATTERY ROOM |
Batteries can be continually recharged here. If you lose this room, you will no longer be able to recharge your Battery. |
| F Block SENSOR CONTROL ROOM |
You can control the Sound Sensor here. If you lose this room, the Sound Sensor will become unstable. |
| G Block BULLET ROOM |
You can reload weapons that take Live Ammunition
here. However, you can only load stored ammunition. If you lose this room, you will be unable to reload. |
In addition to changing weapons and items here, you can get a broad idea of how many enemies there are.
"LEON" may provide you with new items when you are in trouble, so be sure to periodically stop by.
