About Oxygen: First Breath

✦ AI summary

Build and manage a post-apocalyptic settlement dependent on a life-saving Oxygen Center while battling deadly environmental threats like toxic winds, droughts, and frosts. Lead your survivors through resource management, research, and exploration across a devastated world transformed by catastrophic volcanic activity.

STORY


A natural disaster hit us and brought humanity to the verge of extinction. Only a few survived because of "Large Igneous Provinces", these are volcanoes that don't explode but huge cracks open in the Earth's crust and lava just starts bubbling out, oozing across the landscape, releasing tons of toxic gases. The most dangerous thing about an igneous province is that it can keep up the oozing for centuries. With the wind effect, these gases spread all over the world and changed the atmospheric composition. One of these toxic magmatic gases reduced the oxygen level in the air. Sadly, there’s only little oxygen left in the world. Before it's too late for humanity, the Oxygen Center is invented. It generates oxygen by electrolysis of underground water, and the required electricity is generated by using coal but you should be slowly moving away from coal towards sustainable sources of energy. This is the only hope for us...

The world has changed. Start a new civilization for all survivors around the globe. Fulfill your people's basic needs with a nice living place, steady water and food supplies. Research new features and buildings to increase their confidence and education level.

✦ AI summary

Oxygen: First Breath is a survival city builder with engaging resource management and oxygen mechanics that make survival feel genuinely challenging, though players are divided on whether that challenge feels fair or frustrating. Common complaints center on excessive micromanagement (especially job reassignment), difficulty spikes that can wipe out your settlement within seconds, and a slow early game pacing that contrasts sharply with sudden catastrophic events, compounded by a tutorial that doesn't adequately prepare players for incoming hazards.

Oxygen: First Breath is a survival city builder that puts me in charge of a small settlement in a world where there is barely enough oxygen left for humanity to survive. I have to build around the Oxygen Center, keep it running and slowly turn a small group of survivors into an actual community. The first thing I noticed is that the game makes oxygen feel like a real part of the city instead of just another number on a screen. If I cannot keep the Oxygen Center supplied with enough power, everything starts falling apart very quickly. The building and resource management is the part I enjoyed most. I have to keep food, water and materials coming in while giving my people places to live and enough workplaces to keep the settlement running. I can assign people to different jobs, research new buildings and gradually make the whole system more efficient. I also have to think about where I put things because roads and routes matter when I am moving resources around the settlement. It is not incredibly complicated, but there are enough connected systems that I have to pay attention to what I am doing. What makes things more interesting are the environmental problems. I have to prepare f…

Too much micro. Shifting people between jobs depending on the weather gets too tedious over time. Played on normal. Pace at start of game is I suppose a good tutorial but it's super slow and linear. Playing on fastest speed and still feels like waiting. Letting game run on fastest when bad conditions hits can totally smoke your settlement in a very short time. Sickness is crazy. I had 19 people and 1 medical post <20 days in, everyone started having low oxygen in a wind storm and all but 6 died. happened super fast... within 30 seconds on fastest game speed. After that, my game really felt hosed. I didn't have enough people to finish tasks and I had too many buildings with not enough people to run them. I got a second wave of sickness... which pretty much left entire population either a patient or a nurse. I then ran very low on food. I got back up to 12 people but I'm basically out of food. On one hand, being in a state of near extinction is somewhat engaging but on the other hand I'm just waiting on fastest trying to get food production back up. Not really sure if grinding away to recover on this save is worth it.

Nice base building / survival game. The tutorial is short and could perhaps be more in depth, especially as to the hazards that are approaching and theyre potentially catastrophic impact on your community. Great work has also been put into quality of life aspects to this game, so it was always easy to navigate and place roads, objects etc etc I enjoyed the trial and would definitely purchase the full game, for a reasonable price. Looking forward to it.
