About Sylox

Sylox is a short, minimalistic base-building game with a touch of worker placement. You can assign workers to key tasks, unlock new buildings, expand, and defend your growing base against increasing enemy attacks.

Build Your Base

Design and grow your base from the ground up. Place buildings to harvest resources, produce materials, and expand outwards.

Strategically lay down defensive structures to guard your colony against threats. Every building has a purpose, from core infrastructure to actual defensive buildings. Whether you're optimizing production chains or fortifying your perimeter, smart planning is key to survival.

Defend your base

As your base grows, enemies will test your defenses. Build and position defensive structures to protect vital infrastructure.

Combat can be both strategic and chaotic. Make sure your base is resilient enough to handle unforeseen events!

Research and Unlocks

Progress your colony with a flexible tech tree that lets you unlock new buildings, upgrades, and systems as you grow.

Choose your path: specialize in defense, offense, or boost your economy. Each unlock brings new strategic options, letting you shape your playstyle and adapt to the challenges ahead.

Manage Your Workforce

Every worker counts. With a limited crew, you’ll need to carefully assign tasks to keep your base running smoothly. Assign workers to construction, production, transit and defense based on what you need.

Prioritize what's critical. Do you assign a worker to a gold mine or man a turret? The right call at the right time can mean the difference between growth and collapse.
