The listing, Skyraine STEAM KEY has ended.
Skyraine is an action packed platform/missile defender game. Stranded on an alien planet, an ancient turret is your only defense against the invasion. Between waves of enemies rush repair your base and collect supplies and power-ups. As the game progresses new enemies enter the battlefield, each with their own devastating weapons. While aim and precision may help you get through the early levels, only with the perfect strategy can you hope to conquer the final difficulty. Play with up to 3 players in local multiplayer, and face 4 exponentially challenging difficulties.
The Base:
Walled in between a shield generator, your turret lies on the ancient ruins of an extinct civilization. A few rusted girders and ladders are all that remain.
The Power-ups:
Basic ammo- It's unlimited. I don't know how, I don't know why, I don't really care, it's free. Spray and pray, baby.
Shotguns- The most plentiful power-up, instead of shooting one bullet, it shoots like 20. Limited range though.
Discblades- The most versatile ammunition, it'll shoot through almost anything.
Vortexes- The most dangerous one. It destroys anything that gets caught in it's void, so don't shoot things too close.
Zappy's- The best way to clear the screen, hit an enemy with one of these and it will chain to nearby enemies as well. They drop rarely though, so use them wisely. https://store.steampowered.com/app/679430/Skyraine/
