## Overview

Skies End is a free-to-play, early access engineering sandbox from developer and publisher Startek. It drops you into a massive open world where the core loop is simple to grasp but deep to master: gather resources, refine them into complex parts, and use those parts to design and build inventions that let you explore further and collect even more resources. The game launched on October 20, 2026, and is currently available in English, with single-player support, save-anytime functionality, a level editor, and family sharing.

## Highlights

- **Inventor Gadget**: This tool lets you design, paint, and program machines—from rovers and hovercraft to tanks, factories, and even fortresses. The creative freedom is central to the experience.
- **Resource-Driven Progression**: You start by collecting raw materials from the wild, then transport them to factories you build for refinement. This creates a satisfying loop of exploration, construction, and expansion.
- **Open-World Sandbox**: The world is described as massive, encouraging you to push outward with your creations. Whether you prefer building a mobile army or a stationary factory network, the choice is yours.

## Who It's For

Skies End is aimed at players who enjoy hardcore engineering games—those who like tinkering with designs, optimizing production chains, and solving spatial puzzles. If you've ever spent hours in games like Besiege or Scrap Mechanic, this will likely appeal. It's also a fit for sandbox and strategy fans who appreciate open-ended goals and player-driven creativity. Since it's free to play and in early access, it's easy to jump in and see if the building systems click for you.
