Galatron

Galatron is a space shooter game viewed from bird perspective. In the game you start as a commander of a pathetic poorly equipped space ship. Then you can sign up to a various arenas to battle with other commanders to gain money and upgrade your spaceship to some sort of killing machine. As you climb on the ladder of pilots you must compete with harder and more intelligent opponents with better equipped spaceships. Your main goal is to climb to the first place and undergo a final battle with an undefeated Emperor of the whole universe.
What makes game really remarkable and different from other games is the physics-powered universe. Each fight takes place around a central planet so your spaceship, projectiles all debris etc. are influenced by the planetary gravity field according to physics laws. Another great aspect of the game is that your spaceship is composed of attachable components(motors, guns, panels, shields, mine layers..etc.). Each component has its own health and can be destroyed separately. That makes a great impact on a gameplay.
Game can be played in two modes. First mode is Career mode. That is the mode described above where you sign into the arenas and climb on the ladder to defeat The Emperor. Second mode is Skirmish mode. In this mode you can make an custom fight of 2-4 players. Players can be either computer AI players or your friends playing with you on one keyboard. In Skirmish you fight similarly as in Career mode but you don't sign into any arenas, all players fights together in random arena, gain money and upgrade their ships.
