This space shooter / galaxy shooter game takes place in various parts of the universe where diverse advanced civilisations live (Aliens). They are now attacked by another expanding advanced civilisation (Invaders). The player fights for individual native Aliens (trying to protect them) and his or her goal is to destroy all incoming space invaders.

Alien vs Invader: Space Attack is set into a moving hexagonal puzzle system (circular fields in hexagon positions) and is a specific combination of the action, the sharp eye and the speed of logical thinking. Game control is a unique feature that may be briefly described as follows: clicking on a particular point to fire rays into six directions to destroy the incoming invaders (the so-called Hexa Plasma). The number of invaders hit by this type of attack depends significantly on the dexterity and alertness of the player. Besides the primary attack by Hexa Plasma, the game contains also a secondary attack called Space Attack destroying the invaders in the whole hit range. The system controlling the destruction of invaders is innovative to a large degree, however, it is also intuitive and logical – it can be learnt very quickly. Besides Invaders and Aliens the game offers various bonuses (+life, +points, +Hexa Plasma, +Space Attack, -speed) helping the player to achieve victory; the bonuses should thus not be attacked by the player.

The game experience is multiplied by the ambient as the player is transferred into the space where various different extrasolar planets, black holes, neutron stars, nebulas and whole galaxies are shown. With time (by moving up through different levels) the player can get to know a large number of imaginary extra-terrestrial civilisations. Elaborate and interesting graphics helps the player to become more involved in the on-going story of saving a civilisation under attack.

HOW TO PLAY.
The application offers 2 TYPES OF ATTACK:
When attacking by HEXA PLASMA, it is necessary to wait for a suitable moment and to target the attack into an empty falling field in such a way that 6 rays stemming from it hit the maximum number of invaders.
When using SPACE ATTACK it is necessary to wait for a moment when there is a maximum number of invaders in the hit range and to destroy them all by clicking on the attack button. (The number of space attacks is significantly limited and, at the same time, the player needs to count with a loading phase).
The application contains 2 TYPES OF GAMES:
In 1-STAR GAMES (with 1 Alien) the player starts with a limited number of Hexa Plasma attacks and Space Attacks and subsequently, his or her goal is to use a suitable combination of both attacks and an effective firing strategy (with a maximum efficiency of attacks) so as to be able to win the game with the given number of attacks.
IN 3-STAR GAMES (with a bigger number of Aliens) the player starts with a bigger number of Hexa Plasma attacks and subsequently, his or her goal is to destroy all incoming invaders and, at the same time, to evade attacking the Aliens (instead of Hexa Plasma, this type of game contains a possibility to slow down the speed of descending circular fields).

Alien vs Invader: Space Attack – a new type of action-packed space shooting game with emphasis not only on dexterity, attention and sharp eye of the player, but also on the ability to keep track of the action, and on logical thinking.
