Economy and mothership

An army is only as good as the economy that feeds it. This page explains the four resources, upkeep and starvation, the 12 buildings of your ship level by level, the map and its deposits, extractors and towers, moving, trade, the Recycling Center and alliances.

The four resources

Skydos has four resources: iron and silicium, used to build almost everything, energy, which powers buildings and units, and food, which feeds the crew and the infantry. Iron, silicium and part of the energy come from extractors placed on the tiles next to your ship; on board, the Generator produces energy and the Farm produces food.

Your net production is the gross production minus everything that consumes: the ship itself (10 energy per hour), the upkeep of each building according to its level and the upkeep of each unit. That figure, shown at the top of the screen, is the one to keep positive. Each resource is capped by your storage: 1,000 without a Warehouse, much more with one. A full resource simply stops rising.

Terrain matters too. A ship landed on an arable tile produces 50 % more food; a defender on a defensive tile ripostes 30 % harder, and a tower built on such a tile gains as much HP and DEF.

Deficit and starvation

When a resource falls to zero while its net production is negative, the game switches buildings off to rebalance, step by step: first the extractors, then the secondary buildings (Embassy, Trading Post, Recycling Center, towers), then the military buildings, then the infrastructure, and the Farm last of all. The Generator is never switched off.

If the deficit persists, a starvation countdown starts: you have 24 hours (divided by the server speed) to fix it. After that, your units die at a rate of 10 % per hour, the most expensive first. A message warns you before the first losses.

The ship's buildings

Your ship has 15 interior slots for 12 types of buildings. Slots have no effect: you can rearrange your buildings freely. Some are unique; others can be built twice, once the first one is high enough. Everything requires a Command Center, and several buildings require a minimum level of other buildings.

Building	Prerequisites	Max level	Number	Role
Energy Generator	Command Center 1	20	second copy from level 10	Produces energy; consumes food
Farm	Command Center 1	20	second copy from level 10	Produces food; consumes energy
Command Center	—	20	unique	Heart of the ship: construction queue, prerequisite of everything
Barracks	Command Center 1	20	second copy from level 20	Builds infantry
Factory	Command Center 7, Armory 4	20	second copy from level 20	Builds vehicles
Shipyard	Command Center 9, Armory 7	20	second copy from level 20	Builds aerial units and vessels
Research Center	Command Center 1	20	unique	Gives research points
Armory	Command Center 4	20	unique	Makes ammunition; prerequisite of advanced units
Warehouse	Command Center 1	20	second copy from level 20	Raises the storage of each resource
Trading Post	Command Center 1	20	unique	Transporters, market and shipments
Embassy	Command Center 7	3	unique	Join or found an alliance
Recycling Center	Command Center 7, Armory 1	20	unique	Turns part of the losses into recoverable wrecks

The Command Center sets your construction queue: 1 construction at a time up to level 3, 2 from level 4. Durations grow sharply with the level, and they are divided by the server speed. A line can be planned: it keeps its place without debiting anything and starts as soon as your stocks cover it.

Two Farms or two Generators add up their production; two Warehouses add up their capacity; two Barracks, Factories or Shipyards each have their own production queue. A building can only be doubled once the first copy has reached the level shown in the table.

The buildings level by level

Each table gives, for every level, the cost, the duration (server at speed ×1), the upkeep per hour, the building's HP and its main effect. The first level is built instantly.

A building's HP grows by 26 % per level. A building at zero HP goes out of service: it no longer produces, consumes or builds anything until it climbs back above 25 % of its HP. Repair runs beside the construction queue, costs a fraction of the level's price (30 % for a fully destroyed building) and can aim at getting it back in service only or at a full repair.

The map and its tiles

The map is a large grid of hexagons. Each tile has a type, set when the server is created: barren, energy, iron or silicium deposit (more or less rich), defensive or arable. A deposit's yield is drawn at random within a range specific to its type; level 3 of the common research trunk displays it directly on the map.

Tile	Share of the map	Yield per hour	Bonus	Constructions
Barren	40 %	—	—	Defense Tower
Geothermal	10 %	500-2,000 Energy	—	Geothermal Extractor, Defense Tower
Radioactive	5 %	2,000-4,000 Energy	—	Radioactive Extractor, Defense Tower
Iron (Common)	12 %	500-1,500 Iron	—	Iron Extractor, Defense Tower
Iron (Rich)	8 %	1,500-3,000 Iron	—	Iron Extractor, Defense Tower
Iron (Deep)	5 %	3,000-6,000 Iron	—	Iron Extractor, Defense Tower
Silicium (Poor)	4 %	200-300 Silicium	—	Silicium Extractor, Defense Tower
Silicium (Standard)	4 %	300-500 Silicium	—	Silicium Extractor, Defense Tower
Silicium (Rich)	2 %	900-1,200 Silicium	—	Silicium Extractor, Defense Tower
Defensive	7 %	—	Defense +30 %	Defense Tower
Arable	3 %	—	Food +50 %	Defense Tower

Your ship sees 3 tiles around it, more with research. At the centre of the map lies the Grey Zone, the AI's territory, rich in silicium: its deposits produce 3 times more. It stays invisible and impossible to attack as long as its Sentinel towers stand.

Extractors

An extractor is built on a tile adjacent to your ship and makes it yours as long as it exists. It produces a share of the tile's maximum yield, which grows with its level and reaches 100 % at level 20. The curve depends on richness: a poor deposit quickly gives most of its yield, a rich deposit progresses slowly but ends much higher.

Hourly production of an extractor by level, on three deposits
Level	Silicium (Poor) (250/h)	Iron (Common) (1,000/h)	Iron (Deep) (4,500/h)
1	22	43	88
5	81	233	728
10	143	482	1,810
15	198	739	3,084
20	250	1,000	4,500

Each extractor consumes a little energy per hour, according to its level. When your ship leaves its tile, its extractors become orphans: they stay on the map but produce for nobody, and the first ship that lands next to them adopts them.

Defense towers

The defense tower is built on a barren, defensive or arable tile, or on a deposit. It defends your ship even without a garrison: towers within 3 tiles join any siege of your ship and fire with a DEF that grows by 15 % per level, at a range of 5. Several neighbouring towers strengthen each other with the Defense 3 research.

A tower is a structure: units that target structures hit it first. An AI raid cannot take more than 50 % of its maximum HP in one siege; only destruction operations can bring it down at once. A tower out of service does not fire: remember to repair it between two raids.

Your mothership can move to a free tile you can see, at 20 tiles per hour, for 700 energy per tile, paid on departure. In flight, only interior buildings produce. After landing, you must wait 24 hours (divided by the server speed) before leaving again, and no departure is possible less than 30 minutes before an expected attack or during a siege.

Moving lets you reach better deposits, get closer to an alliance or get away from an overly aggressive VM. The extractors left behind become orphans: a move needs preparing.

Trade

The Trading Post gives one transporter per level. Each transporter carries 1,000 units of resources at 20 tiles per hour. You can send resources directly to another player or publish offers on the market, open to everyone or reserved for your alliance. A delivery heading for a besieged target turns back.

The merchant converts iron into silicium and back, and redistributes your resources, for a few coins per operation (free with the Production 8 research). Shipments can also be scheduled: they leave on their own as soon as your transporters and stocks allow, in the order you planned them.

The Recycling Center

With a Recycling Center in service, part of your units lost in combat become wrecks: 5 % plus 2 % per level of the building, and always all of them for special units (vessels, support units). A wreck is recovered instantly for 48 hours, for 100 % of its production cost in resources or a few coins. After a big battle, it is often the cheapest way to rebuild your army.

Alliances

Level 1 of the Embassy lets you join an alliance, level 3 found one. An alliance shares a chat, a treasury funded by its members, an ammunition stock, and allows reinforcements, resource shipments and coordinated attacks. The common trunk research (level 5) shares the vision of all its members.

The Guild is the alliance's base on the map. Very tough (60,000 HP at the first level), it moves up to 25 tiles at a time and can host a garrison paid by the treasury. Its level, up to 20, sets the number of members: from 5 to 60. It also sets its vision, shared with all members whatever their technologies: 3 tiles at the first level, +1 per level, so 22 at the last; it is suspended during a move. The AI can besiege it and loot the treasury; if it is destroyed, the alliance is dissolved.
