Megastructures – stellaris wiki gas unlimited houston

##########

There are three types of megastructures: gateways, habitable projects and galactic wonders. Systems can only host one megastructure (Unless its a habitat), except for gateways, which can be built in systems where there is already a megastructure. Habitable megastructures (habitats and ringworlds) can be colonized but will be irreparably destroyed if a crisis overruns them. Galactic wonders provide massive bonuses and cannot be destroyed by any crisis, but are limited to one per empire. All megastructures have a different textures depending on the empire that built them.

Except for gateways, ascension perks are required to unlock the ability to build new megastructures. An empire that conquers a system with a megastructure can use it, but if the construction was partial, it will not be able to continue its construction without the required ascension perk. Damaged megastructures found through exploration, however, can be reconstructed by unlocking the Mega Engineering technology. The following ascension perks allow for the construction of megastructures:

While exploring the galaxy, empires can electricity experiments for 4th graders find abandoned gateways that were once part of a massive, galaxy-spanning network. Reverse-engineered from encountered abandoned gateways, these megastructures require the Gateway Activation technology and can be used to travel directly to any other active gateway in the galaxy. Reactivation of gateway takes 2 years and costs 6 000 energy and 2 500 alloys.

When the first gateway in the galaxy is re-activated, another random gateway will also be re-activated along with it. As opposed to wormholes, both gateways must be owned by the same empire or two empires with open borders in order to be able to travel through them. Gateways of opposing empires are unusable during war, even when the system is occupied. However, systems with gateways count as bordering for the purposes of diplomacy, so every opened gate increases diplomatic tension between all active gate-owners. Claims cannot be extended through gateways. Additionally, gateways are able to greatly enhance and simplify trade infrastructure.

Eventually, empires can build their own gateways by researching the Gateway Construction technology. Notice, that this tech requires having some civilization with an access to pre-existing gateways, so if gateways were disabled during galaxy creation it is impossible to build any new. Each system can have only one gateway, but black hole systems with an L-Gate can also grade 9 electricity unit test answers have a regular gateway constructed. Gateways can be built in systems in which there is already a megastructure. The construction site is built in only 3 years and costs 100 influence and 2 500 alloys. Upgrading it to a gateway takes 5 years and costs 6 000 energy and 2 500 alloys.

Some Black Hole systems are home to L-Gates. These heavily modified gateways cannot be activated with the Gateway Activation technology. Upon first encountering one, the L-Cluster entry will be added to the Situation Log, requiring the collection of 7 L-Gate Insights. Insights can be obtained from investigating anomalies, defeating certain enemies, researching the rare L-Gate Insight repeatable Voidcraft technology or asking the Curator Order for an insight every decade ( -5000 Energy).

Opened L-Gates grant access to the L-Cluster, a cluster of stars located north-east of the galaxy and entirely inaccessible through the regular hyperlane network or experimental subspace navigation and too far for Psi Jump Drive range. The L-Cluster contains a unique Strategic Resource: Nanites. If a ringworld is built inside the L-Cluster, then while n gas price its construction will remove the planets in the system and make the original resources unavailable, the uninhabitable sections of the ringworld will contain some of the the resources instead as the habitable sections are completed, sometimes more than there were originally.

Immense in both radius and scope, ringworlds encircle their system’s star and award their owner four ringworld sections when fully constructed. The carefully designed ecosystems and finely-tuned atmospheres of their sections offer perfect living conditions towards all residing species, granting inhabitants 100% habitability on the ring world’s surface.

Ringworlds cannot be built around black holes or in systems with multiple stars. All planets in the system are consumed upon the completion of the frame. As habitable sections of the ringworld are completed, additional, uninhabitable sections will also appear in the spaces between them. These serve little purpose except if the ringworld is built in the L-Cluster, in which case they can be mined for the unique electricity history timeline Strategic Resources present in the cluster.

• A number of workers might go missing, delaying the construction for a month. Two months later it will be revealed that one of the planets used in the construction had a species of furry worms the workers have grown fond of. You are given the option to either exterminate them and delay construction for a month or allow them on the building site. Whatever choice is made a month later the worms will be found feeding on the missing workers underground and be exterminated.

• Another empire might contact you, thinking that you are making weapons of mass destruction on your ring world. They will want to inspect the ring world. If you accept the request the construction will be halted and the empire gets the Request accepted opinion modifier ( +40 opinion, -2 yearly). If you declined they get the Request refused modifier, with a penalty of -40 opinion.

• Another empire can contact you, asking you to allow them to base a group of researchers on your ringworld. If accepted, no time delay will occur, and after a period of time has elapsed (approx. 31 days from acceptance) you will receive 250 engineering points. The empire asking will be a fanatic egalitarian and may be on any diplomatic relation level with your empire. There is a Request accepted opinion modifier ( +40 opinion, -2 yearly).

Given sufficient resources to construct them, habitats allow even a compact empire to rapidly grow its population, as any number of habitats may be constructed at a time, they can be constructed around a wide variety of celestial bodies, and their buildings are relatively quick to set up. Since research and unity penalties scale towards empire sprawl rather than number of colonies gas and supply shreveport, they are highly efficient for tall empires, as Habitat districts provide a larger amount of housing and jobs compared to regular planet districts. Gestalt Consciousness empires can build housing buildings on habitat, further improve its performance.

Ringworlds cost 45% less alloys per district than habitats (275 for ringworlds vs 500 habitats), but 95.5% less influence (1.5 for ringworlds vs 33.33 for habitats). This calculation changes slightly with the Master Builders ascension perk due to the increased size of habitats (from 6 to 8 districts). In this case, Ringworlds cost 27% less alloys per district than habitats (275 for ringworld vs. 375 habitat), and 94% less influence (1.5 for ringworld vs. 25 for habitats).

Ringworlds can only be constructed one at a time, and their superlative size greatly increases the empire sprawl, but it serves as an ideal place for mass-producing Energy Credits and Food since ringworld section has no deposit limit. Since they consume all planets in their system when built (other than the star), it is generally recommended to construct them in systems that are poor in natural resources. If an empire has no influence banked and earns 5 influence per month, it will take 1 200 days to earn enough influence to build a habitat which is the same amount of time it takes to build the habitat with the Master Builders ascension perk. Under the same conditions, a ring world may be started every 1 800 days, but allows for a construction that takes 21 000 gaslighting days (or 14 000 days with the Master Builders ascension perk) and only one section can be built at a time. This means that for maximum expansion speed, one should alternate the construction of ringworlds with that of habitats.

These megastructures require the Galactic Wonders ascension perk and each can only be built once per empire. However their bonuses are massive and they cannot be destroyed, only captured. Habitats can also be built in the same system as Galactic Wonders. Galactic Wonders cannot be built if there is an existing orbital station (mining/research station), however they can be built around secondary and tertiary stars in multi-star systems. Each Galactic Wonder starts with a construction site that provides no benefit, however each subsequent construction phase will bring increasing bonuses, culminating with the end of the megastructure construction.
