# Chapter 2. The Game

# 2.1. Rules of the Game

## 2.1.1. Ship Movement

Each player controls one ship.

The ships can rotate, accelerate, shoot and lay mines.

## 2.1.2. Energy

Each ship has an amount of energy (refer to the game options for values).

Ships need energy for rotation, acceleration, shooting and laying mines. A ship gets energy from its solar panels. The amount of energy a ship gets depends on the distance from and direction to the sun. A ship gets more energy near the sun and less energy near the border. It gets the full amount of energy if the sun shines directly on the panels and less or even no energy if the sun shines at an angle to the panel or to the side of the panel.

If a ship has no energy it can't navigate or shoot.

## 2.1.3. Hit points

Collisions with own or other bullets or mines decrease the hit points of a ship. If two ships collide, the weaker ship is destroyed and the hit points of the stronger ship are decreased by the hit points of the weaker ship plus an amount (Crash Damage). A ship is destroyed when it flies into the sun.

## 2.1.4. Bullets and Mines

Bullets fly around the sun like a ship.

Mines have an amount of energy to stay at the same position. When the energy is spent, the mine falls into the sun. Mines near the sun need more energy than those which are further away.

Mines can be destroyed with bullets.

By default a ship can have 5 bullets and 3 mines on the screen.

## 2.1.5. Powerups

From time to time powerups appear on the play field.

There are four different powerups:

- Mine: The maximum number of mines is increased for the player.

- Bullet: The maximum number of bullets is increased for the player.

- Energie (yellow sphere): The player gets energy.

- Schild (blue sphere): The player gets hit points.
