Mars Matrix

The game only uses one button, as the triggered actions differ according to the timing with which the button is pressed:

• Normal Shot: Tap A button. Shot power increases with level (max 8), which depends on EXP points.
• Piercing Cannon: By not pressing A button for at least 1 second, press A. The attack has a close range that can hit multiple targets. The attack strength is higher than Normal Shot, and the attack strength increases against target closer to player's fighter. Piercing Cannon's shot power does not change based on level.
• Mosquito: When GHB is full, hold A button for 1/4 to 1/2 second. A barrier is activated afterwards, which damages contacting enemy. With active barrier, player's fighter is invulnerable, the GHB gauge is drained, and enemy bullets are attracted to player's fighter. Releasing A button while GHB is not empty causes attracted bullet to fire in a direction away from player's fighter when A button is released. A repelled bullet that hits an enemy is converted to cube.
• Gravity Hole Bomb: When GHB is full, hold A button until GHB gauge is emptied. When activated, an explosion damages all on-screen enemies and destroys all on-screen enemy bullets.

Each fighter has a 10x12 pixel hit box at the front of the unit. Player gains 1 life at 100000 EXP. The fighter can only be destroyed by colliding with enemy bullet, not other objects.

• Mosquito 01: normal speed, wide blaster weapon, lower normal shot damage
• Mosquito 02: high speed, laser shot weapon, higher normal shot damage

• 1UP: Increases player's life stock by 1.
• Cube: Increases experience, and recharges combo meter. The bigger cube grants longer recharge time.

When player's fighter captures a cube, player's EXP is increased and the combo meter is filled, causing successive captured cubes to have increased EXP and longer recharge time until combo meter is depleted.

Combo meter can be depleted if player's fighter fails to capture a cube for a prolonged time period, or if player's fighter is destroyed.

Cubes can be found by destroying (a portion of) an enemy, or hitting enemy with repelled bullet.

When EXP is sufficiently high, player's level is increased. Increased level causes fighter's normal shot to be more powerful, and increases the number of cubes needed to completely fill combo meter. In addition, higher EXP value causes more points to be rewarded for activities that increase player's score.

There are 6 levels in the game each with a boss that you need to destroy in an amount of time and a briefing of the next level.

1. Armed Satellite Phobos

Briefing: We, in order to gain control of the airspace of Manitily, planned to secure Phobos satellite.

Location: Phobos

Boss: Small satellite armed with guns, lasers, and electric mines. Its wings can be shot off.

2. Descending to Mars

3. Surprise Attack

Briefing: The "ACID" unit that belongs to the Number 201 independent armada is starting to make a front alone. The goal of this mission is to secure Maneris Starport that has been occupied by the rebellion. Since this mission has been classified as extreme, no support will be available.

Location: Maneris Starport

Boss: A giant crustacean mech that deploys seed-like aircraft with different patterns of firing bullets. The head turns into a cannon and the pincers turn into gatling guns when destroyed.

4. Red Sky Project

Briefing: With the success of the last mission, the spaceport has been secured. The decision has been made to alter the next assignment to mission code 075. The ACID unit should assemble with the fleet and destroy the remaining enemy forces. Keep in mind that there is a powerful gravity force high in the mid-Atlantic.

Location: A small rebel armada, Mars Mid-Atlantic.

Boss: A huge command ship known as the Exodus. It can launch from the front a fish-like escape pod.

5. True Darkness

Briefing: The remaining enemy armada and its command ship "EXODUS" has been destroyed. The remaining enemy forces are assumed to be down to 20% approximately. The mission is entering the final phase. Our fleet will remain in orbit backing up the ACID unit while you attack the headquarters of the enemy.

Location: Rebel train station.

Boss: An armored train of 5 cars. 3 cars have a gatling cannon and two doors that bring out turrets, mines, and fighters. The fourth car has several turrets. Inside is a legless mech with two chain guns. The last car is the engine car with arms with bazookas that shoot dozens of electric missiles.

6. Forbidden Fruit

Briefing: None

Location: Rebel Headquarters

Boss: There are three bosses with the same time limit. The first boss is a hovering saucer that can turn into a crustacean or a spiked wheel. The second boss is a control tower. It is between two control units that shoot sprays of missiles. The third boss has two stages. The first stage is a mutant flower that shoots out a seed-like ship and an almost impassable pattern of bullets. The second stage is the sorceress behind the death of the ancient Mars civilization, with a cocoon and skull form until she is destroyed.

At the end of each stage, player gains points based on following criteria:

• Time: Depends on how many seconds left after destroying last boss in the completed stage.
• Level: Depends on the just completed level number.
• Shootdown: Depends on the total points gained by destroying enemy units.

Total Score earned for completing a stage is the sum of points in Time, Level, Shootdown fields.
