Gameplay

For the gameplay of this arcade scrolling shoot'em up, the main goal of this game is get through the seven levels and escape the body of the infected woman. To achieve this goal you have to pass seven levels and defeat a boss at the end of each level, each one more difficult than the last. At the end of the last boss, you exit the no longer infected body and your ship gets picked up. For each level you have to defeat as many enemies as possible, but it's not essentialy necessary, because your goal is to get to the end of the level, where you need to kill the boss in order to get to the next stage.

You die with one hit, but have multiple lifes. A special feature of this game is the use of the tentacles as you only proctection, because you can use them as your shield. They are invincible and block incoming projectiles, and because they follow te motion of the ship and you die really fast, they are indispensable to master and control.

When it comes to doing damage, you have different ways of doing so. One way of doing damage and the most basic one is the default projectile of your ship, which doesn't deal much damage.

The next ways of doing damage are available once you get power-ups:

• The first power-up you get always gives you tentacles, regardless of the color, and the tentacles deal double the amount of damage of the normal projectiles per tic if the ends of the tentacles are touching an enemy, and you deal one tic of damage every 0.1 seconds. Apart from the on-hit tic damage, the tentacles also shoot one projectile each.

• The blue one are the homing missiles. This makes your ship shoot 4 missiles every 1.5 seconds that seek for the nearest enemy that gets close to the missile. If you grab another blue power-up, this will upgrade to 6 missiles.

• The red one are the lasers, which makes your projectiles turn into lasers, and if you already have lasers and pick up another laser power-up, the lasers upgrade.

• The last form of damage coming from a power-up is the shadow shells, which improve your tentacle on-hit damage and makes the projectiles that come out of the tentacles double and become dependant of the tentacles' angle, but restricted to 16 ways. If upgraded your on-hit damage becomes greater.

Have in mind that if you already have a power-up and grab a different one, the projectiles will change to the upgraded version of the last power up grabbed.

Apart from the projectiles power ups, there is also a different power-ups that go independently, and it is the bomb power-ups. These power-ups make you drop a bomb in free fall from you ship that deal a good amount of damage. If you already have a bomb power-up and grab another, you will drop 2 bombs instead of one in a 0,1 second delay.

Controls

Game flyer which explains the controls of the game

The controls of this game are very simple in the arcade, you only got a joystick to move the ship around a button to shoot. The interesting part of this controls are the tentacles, which move according to how you move the ship, for example if you move forward, the tentacles will move backwards, ande viceversa.

If you want to play the 2 players mode, it works alternatively. First the first player plays until he dies and then the second one, and the scores are compared.
