Mission
Tharsis is a mountainous region on Mars where hundreds of caves have been discovered. These caves contain precious gems which are heavily guarded by enemies and alien life forms.
Your mission is to explore these caves, destroy the enemies and collect as many gems as possible. Collecting gems will increase your health and gain points. You will gain extra bonus points the more gems you collect and enemies you destroy.
There are 100 cave levels to complete, each one generated completely randomly so no two levels are ever the same. As you progress through the levels the caves will become larger, more complex and you will encounter more challenging enemies, aliens and obstacles.
Enemies
You will encounter many different enemies as you progress though the caves. Some guard their position and don’t move, whilst others form waves of enemy spacecraft which will follow you. The more powerful enemies will take serval hits to destroy.
Enemy Bosses
Watch out for enemy boss spacecraft. Some of the Key Cards are in the possession of enemy bosses so you will need your weapons to destroy these and collect the Key Card.
