Oxygen Not Included (ONI) throws you headfirst into the chaotic and unforgiving world of deep space colonization. Survival isn't just about finding food and water; it's about meticulously managing resources, understanding complex systems, and keeping your colonists alive in the face of constant challenges. This guide provides a foundation for newcomers, covering essential early-game strategies.

Prioritizing Your First Steps: A Foundation for Success

Your initial days in ONI are critical. A poorly managed start can lead to rapid colony collapse. Focus on these key areas:

1. Secure a Stable Power Source:

Early game power is essential. Start with solar panels, supplemented by wind turbines if available. Strategically place these to maximize energy generation. Neglecting this will severely hamper your ability to progress.

2. Oxygen Production:

The name of the game is, well, oxygen. Prioritize building electrolyzers to generate oxygen from water. Ensure a consistent supply of water is available for optimal oxygen production.

3. Temperature Regulation:

ONI's environments fluctuate wildly. You'll need to establish a system for temperature control. Early game, this primarily involves using liquid-based cooling systems to keep your base at a comfortable temperature for your duplicants. Failing to do so can lead to heatstroke or freezing.

4. Food and Water:

Meeting your colonists' basic needs is vital. Start by planting basic crops such as berries or mealwood. These provide sustenance and can be grown efficiently with minimal infrastructure. Ensure you have sufficient water to both support life and to power your electrolyzers.

5. Waste Management:

Managing waste is paramount. Utilize toilets and appropriate waste disposal systems to prevent disease and contamination. Unattended waste can quickly spiral into a crisis, polluting your environment.

Beyond the Basics: Mastering Resource Management

Once you've established a basic colony, focus on refining your resource management. This includes:

Automation: Learn to automate tasks using pipes, filters, and programmable devices. This frees your duplicants to focus on other essential tasks.
Building Expansion: Carefully plan your base layout. Consider future needs, and avoid constructing cramped or poorly organized areas.
Resource Prioritization: Efficiently use your resources. Focus on essential supplies first before expanding into non-essential projects.
Duplicant Management: Assign appropriate tasks to your duplicants based on their skills. Specializing duplicants' roles can significantly increase efficiency.

Facing the Challenges: A Word on Advanced Gameplay

ONI’s challenge lies in its complexity. As your colony grows, you’ll face more advanced challenges, including:

Disease: Maintain a clean and healthy environment to prevent outbreaks.
Stress: Monitor your duplicants' stress levels to avoid burnout and negative behaviors.
Resource Depletion: Plan for long-term resource sustainability.
Advanced Technology: Explore advanced technologies such as nuclear power and automation upgrades.

Mastering Oxygen Not Included requires patience, planning, and a willingness to learn from your mistakes. This guide offers a solid starting point. Embrace the challenge, experiment, and soon you'll be thriving in the depths of space.
