[Vanilla + DLC] Research Requirements
Enhance Your Oxygen Not Included Experience with Research Requirements
Are you looking for a fresh challenge in Oxygen Not Included? Do you find yourself blitzing through the tech tree with little resistance? The “[Vanilla + DLC] Research Requirements” mod introduces a compelling layer of strategic depth, transforming your technological progression into a series of earned achievements. This mod ensures that every new advancement feels like a genuine reward for your efforts, making your journey of colony development all the more engaging.
A Deeper, More Rewarding Tech Tree
This mod injects a dose of realism and challenge by imposing prerequisites on nearly every researchable technology. To even gain access to a particular research project, your duplicants must first demonstrate a certain level of proficiency or experience in a related field. This thoughtful design turns the act of researching into a mini-quest, encouraging players to master existing systems before unlocking new ones. The early game, in particular, becomes a more extended and demanding phase, as familiar technologies are no longer readily available, forcing you to adapt and overcome obstacles with fewer advanced tools.
Customization for Every Colony
The developers understand that player preferences vary. The “[Vanilla + DLC] Research Requirements” mod offers robust customization options through a JSON settings file. You can fine-tune the difficulty to perfectly match your desired level of challenge. Scale the requirements up for an intensely demanding experience or dial them back if you find certain prerequisites too demanding. Furthermore, the ignore list feature provides a safety net. If you encounter an unavoidable roadblock or a specific requirement that doesn’t fit your colony’s unique circumstances, you can choose to bypass it. However, this feature is best used sparingly to maintain the mod’s intended challenge.
Key Features at a Glance:
- Introduces prerequisites for most research projects.
- Enhances early-game challenge and extends its duration.
- Transforms research into rewarding, earned achievements.
- Highly customizable difficulty through JSON settings.
- Optional ignore list for specific, problematic requirements.
If you’re seeking to breathe new life into your Oxygen Not Included playthroughs and crave a more strategic approach to technological advancement, this mod is an excellent choice. Prepare for a more deliberate, challenging, and ultimately more satisfying path to mastering the harsh environments of space.
