Pokeshells Abound

This is a fantastic seed to start a new game of Oxygen Not Included. The closest starting asteroid is a radioactive swamp map. This is a bit of a tricky map to get to grips with, and it doesn’t give as much power output as other maps with the radioactive feature. However, it can support the entire pokeshells manufacturing chain.

Oxygen Not Included: Best Power Sources

Restricted by the finite resources in Oxygen Not Included, judging which power source is best to power a growing colony can be difficult.

Other great features of this map seed included 4 natural gas, cool slush, polluted water vent, 2 salt water, 2 cool steam, chlorine,1 aluminum, 2 gold, 1 minor volcano, 1 hot polluted oxygen, and 3 oil wells. These are all very useful resources in this resource management style game.

Direct Passage To Cold Biome

Another map seed that starts with a nearby radioactive swamp asteroid. These can be useful for boosting power output, although there are better asteroids for producing power. One of the best benefits of this ONI seed is that there is a large number of Hatch on this map. And with this many Hatch, it means there will be plenty of free coal available to collect.

Other features of this seed include a steam geyser, as well as water. One major benefit is that it offers a pretty direct route to the cold biome, without contracting Slimelung.

Possible Risk Of Slimelung

The third Oxygen Not Includedgame seed here starts with a nearby radioactive swamp asteroid. And although this isn’t the best asteroid to have close, it isn’t the worst either. However, players need to be aware that there is a potential risk of Slimelung, due to how much slime is around on this map. But it is worth the risk.

Plenty Of Metal Near The Start

Once again, this seed has a close radioactive swamp asteroid close by. It is surprising how many great map seeds have this as a primary feature. Many players seem to prefer this kind of asteroid close at hand, even though there are, on paper, better ones.

However, this radioactive swamp asteroid is metal-rich, and this is a big bonus for this map. Other useful resources on this map include a slush geyser, a gold geyser, and a minor volcano. A useful combination, especially during the mid-game.

An Oil Well And An Iron Volcano

This ONI seed has the usual radioactive swamp asteroid nearby. The Oxygen Not Included community seems to prefer this type of asteroid to be available at the start of a new game. A great bonus for this map seed is that there is both an oil well and an iron volcano available almost from the start of this open-world game.

All The Oil You Need

Once again, the usual radioactive swamp asteroid is close to the starting point with this map seed. But what makes this map seed special, is the fact that there are two leaky oil fissures very close to the start. This is an incredibly useful resource to get your game off to a great beginning.

Other resources abound on this map. This includes 2 cold steam vents, both an iron and a chlorine volcano, polluted oxygen, and natural gas. These are all very valuable starting resources, making this a very good ONI seed.

Two Copper Volcanoes At The Start

As usual, there is a radioactive swamp asteroid close by. Most good ONI map seeds have this feature. But what really sets this seed apart from others, is that it has two very useful copper volcanoes at the start. This is just about perfect for the start of this resource management game.

There is a profusion of other useful resources given by this seed as well. A natural gas geyser, chlorine gas vent, iron volcano, cool slush geyser, hydrogen vent, 2 cool steam vents, and polluted water. This is a huge volume of resources.

Cobalt In The Starting Area

Oxygen Not Included Seed V-SNDST-C-558027971-0-01

This last entry is not a seed, it is a specific starting location on the default map. But it is well worth including for one very good reason. It has the rare resource cobalt in the start area. Any experienced ONI player will explain that finding cobalt on a map is a fortuitous event, and in some games, it is not available at all.

There are also plenty of other resources close by. Including iron, natural gas, cool steam, hydrogen, water, salt water, cool slush, and oil. This profusion of useful resources combined with the cobalt reserves, make this ONI map something special.
