About The Eternal Castle: Remastered
The Eternal Castle: Remastered is a side-scrolling adventure set after the collapse of a cyber-net society. You play as Adam or Eve, who returns to Earth on a mission to find a missing companion and gather materials to restore the self-sufficient facilities that support the last human colonization units in space.
The mission
Before the fall, extraterrestrial human colonization units built survival facilities around Earth to create self-sufficient ecosystems in space. Terrorist attacks on the main core servers halted the procedure, and after global wars shut down the systems, pollution, climate change, radioactive warfare and resource shortages killed most of humanity. The remaining units survived in space for several years before exhausting most of their supplies. Scavenger units were sent to Earth to collect materials and restore the facilities, but one unit never returned. The protagonist believes she is in danger and sets out to find her, despite considering the mission a suicide run.
Explore and fight
You can take time to experience the atmosphere or speedrun through the post-AI fallout. The journey leads through the Ancient Ruins, the Forgotten City, the Unholy Lab and the Eternal Castle. You fight through the ruins, shoot your way through the city and sneak past monsters in the lab.
The eternal dream
As Adam or Eve, you meditate, predict and wake within an eternal dream. You can repeat the dream as many times as you can before reaching the end. Along the way, you can collect all four GLIDERS to power up your ship, use up to 10 different weapons, unlock up to 10 different items and find all missing FRAGMENTS to get back home.
