Embark on a side-scrolling adventure through hostile alien landscapes in Sisyphus Paradox, an indie game where each level is a new challenge. Navigate treacherous environments filled with deadly obstacles as you fight your way back to Earth.
About this game
Sisyphus Paradox mixes traditional side-scrolling shoot 'em up gameplay with many roguelike mechanics, such as procedurally generated star maps to explore, bonuses that are persistent between runs, and multiple different builds you can try to conquer your enemies. Course through hand-drawn battlefields, lose, try again, until you solve the Sisyphus Paradox.
The Story: An ordinary person finds themselves flung across the galaxy. They are lost far away from home, with a voice in their head as their only guide and companion. Strange alien looking creatures are in pursuit. Help them fight their way back to Earth.
Features
3 Playable Ships: Each has very distinctive mechanics that go well beyond simply having different stats.
56 Unique Items: You have weapons, passives and active-use specials, all of which can be upgraded, and some can change significantly as they level.
10 Timestreams: Each more challenging than the last. As you become better at the game, more options are revealed to you.
The Antagonists: There are three different factions to face, each with their strengths and weaknesses, as well as their own Bosses and Minibosses.
Infinite Universes: Choose your path across the stars as each run will offer you a new map to explore, full of random encounters and enemies to deal with.
Multitude of Options: Each ship has slots for two weapons, two passives, and two specials, giving you a multitude of build options with which to approach each game.
Sisyphean Task: Every time you are defeated you set out on a new journey, hopefully moving closer to your end goal, this time with new bonuses to help you out.

Major Update 0.5.3: New Ship Class!
At last, the first major update for Sisyphus Paradox is here: We're proud to present BlissCo's StarBlaster™ Pro, the jewel of commercial weaponized entertainment! Designed to mirror BlissCo enemy ships, the new ship class -dubbed the "Nano Ship"- offers an entirely new playstyle based on picking up Nanite drops from the battlefield, which replenish the ship's main resource, its Armor. Armor in turn, is used both to absorb damage and to fuel Specials. Alongside the new ship we are releasing nine new assets to match the BlissCo approach to combat. Drones and other autonomous units to supplement your firepower, but also a few more close-range assets to help you dive into the heart of enemy swarms in order to pick up those precious drops! Of course, we are still working on improving the game and paying attention to tester feedback, so this patch also includes various bug fixes and game improvements, as well as a number of balancing tweaks. Having reached this first landmark, we intend to soon publish a roadmap for the remaining major updates in our course towards the final game release. In the meantime, we hope you have fun with the game and keep picking up those Nanites if you want to make it! Here is the full changelog for version 0.5.3: Added Third ship class, inspired by BlissCo enemy models, and dubbed the "Nano Ship" Nine new ship assets Tooltips on the ship selection screen showing the main differences between ship classes Savegame incompatibility management that will delete the current run after an update (and compensate you with some Chrono Crystals) Fixed Fixed a display bug that would show future hull to be repaired even after credits would run out Asset description list item now has variable size, to prevent line breaking Stopped the Junk Heaven event from appearing in all acts instead of just Act 3 Changed Jury Rig system now functions differently for each ship type to make it more useful across the board Emergency Hull Condenser is now specific to the Bio ...Read full article on Community Announcements (Kaths)Patch NotesOfficial
