Alien Outbreak 2: Invasion 1.1

He has to defend the Galarion system from the attack of four hostile alien races, which are sending more than forty types of battleships into action. In each of eight missions of the game he will have to battle nine waves of attacking hostile destroyers and win exciting duels with a space fortress. With every new wave your enemies grow more and more aggressive, their armament becomes stronger and more powerful and ships are more maneuverable. But your cosmo fighting skills, little by little, improve. Different bonuses fall out from the destroyed enemy ships: they improve your basic weapon, provide your ship with additional super-power armament, make the protective systems better and supply you with other useful tools.
