About Operation Octo

Operation Octo - about the game


Dr. Odin, an octopus scientist, has teamed up with his Dolphin colleague to put a stop to underwater skeletons’ reign of terror!

In this action Tower Defense game, you fend off hordes of skeletons by strategically placing sea creature turrets. Beware that as your line of defense falls, this quickly turns into a game of survival where you dodge around for dear life!

The game currently has 7-9 hours of playtime across 3 unique biomes, with more biomes to be added via free updates!

Features
  • Unlock Turrets: Your arsenal is filled with mechanized sea lives! Those cool inventions (such as Pistol Shrimp, Navy Seal, and Death Ray) will handle the fight. You’ll discover new turret types one after another - Figure out how best to utilize each of ‘em!

  • Skeleton Enemies: Did you know that most humans who ever lived are dead? Tons of skeletons end up in the ocean, and are terrorizing local ecosystems. Fight sword-swinging pirates, poison-wielding chemists, and even skeletal dragons… Those skeletons are sure to shake up your playstyle at every turn!



  • Unique Biomes: As you adventure the seven seas, you’ll add more creatures into your turret collection, and face new and exciting dangers. Adapting to changing environments is key to survival: Don’t misstep into a toxic brine pool, or forget your light in the darkness of the deep sea.

  • Turret Upgrades: Skeletons will sometimes drop a variety of Elixirs. Use them to boost turrets into different forms! Will you turn a turret into a frosty ice machine, a powerful mutant, or a shadowy stealth weapon?



  • Boss Fights: Special levels featuring larger-than-life boss enemies with formidable abilities!

  • Awesome Upbeat Soundtrack: Seriously, the composers are amazing

  • Mostly created by one person, while doing college


“The ocean awaits us to reclaim - Let the Operation Octo commence!”
- a message from Dr. Finn the Dolphin (who really needs your help because he’s too lazy to do the work himself)
