NevoSoft Arcadrome: Space Stalker

Arcadrome is a new fantastic 3D action game. Your goal is to pickup all the crystals scattered over the field. When you are finished you get to go up the next level.

There are many monsters in Arcadrome, each one has its own tactics to prevent you from completing your noble work. Some of them are somewhat stupid, but the rest are quite sly and represent a serious danger. They can shoot at you, mine the field ahead of you, steal your crystals and so on. Be careful of meeting your unknown foe.
At the end of every ten levels the main monster appears. This is the most terrible and guileful boss of the game which you will need to destroy to get to the next level. When you pass every ten levels you get ability to save the game.
Every level lasts for a fixed time, and for every idle time, you lose one life.
You must avoid mines placed in the field. To pass additional levels you catch the bonus power-ups flying around the field. These bonuses give you many different advantages in your difficult struggle. Without them you cannot do serious damage.
