Saturn Blue
Saturn Blue is a platform shooter which features 35 unique upgrades, 6 of which are secret upgrades and an additional 6 of the upgrades can be purchased multiple times.
You start out weak with barely any movement capabilities, but in time you’ll be fast and deadly using a wide variety of weapons and gadgets – none of which become completely obsolete.
Unfortunately you are fighting a horde of constantly evolving robots which will develop and refine new abilities as you player higher and higher mission levels.
The main storyline consists of the first 25 levels after which you may face the boss, but you will likely have to play until at least mission 30-35 until you have enough upgrades and knowledge to beat the boss.
In total there are over 100 numbered missions, 2 secret challenge levels and a boss level.
Good luck and please enjoy.
