Zones

Zone	Information
Headquarters	Where your journey begins. No matter how many times you've failed, there's a chance to succeed as long as you have a place to call home like this one. The player's starting point and command center, where the actions listed below can be done through the Sage interface. HQ actions Shows how many days the R.A. campaign have passed. Enter Build Mode to place Constructs in the Base perimeter and shows the amount of Constructs in the Base perimeter. Support Department: Manage Electrolyte Isotonics. Provisions: Self-explanatory. Inventory: Shows how many resources the player has in their stock. Research & Development: Build Constructs and Support Items. Road of Prosperity: See here for more information. Crude Gold Treasury: Shows how many Crude Gold the player has in their possession. By Chance, By Fate: A log of Events and Dispatches throughout the R.A. campaign. Emergency Evacuation: Abandon the R.A. campaign.
Conflict Zone	Chaotic warzone. Here you might encounter warriors that serve different lords ameer. Fight enemies in a repeatable operation like the usual Arknights gameplay.
Mountain Pass	Enemies' stronghold. They will be incapacitated the moment we take the place. Perhaps we can surprise them with an unwarned attack. Elite Raids spawn from time to time in the Mountain Pass until conquered, where the player must destroy the Mobile Battle Tower in the zone within the given time limit. Destroying the tower additionally grants a large amount of resources.
Resource Zone	Unexploited mines lie here. Our base construction can take advantage of its resources. The zone where materials are gathered.
Hunting Zone	Wild beasts live here. Here we can hunt for our food. The zone where ingredients are gathered.
No Man's Land	An unclaimed land that sees suspicious peace. We might want to try our luck here and see what we can find. Engage special bosses with absurd stats to obtain rewards based on how much damage was dealt to the boss within the given time limit, even better if the player manages to defeat the boss.
Event	Crowds and clamor. What awaits us here? A random event, like that of Encounters in Integrated Strategies.
Dispatch	A caravan is looking for your company during the journey. Perhaps the trip will reward us. Operators can be sent away for missions which merits various rewards here.
Black Market	This place is all about bargains. Give out what we have, and the right customers will come to us paying the right price. Exchanges Crude Gold for resources and tools. Unlike other zones, the Black Market will always be present on the northwest corner of the map and entering it does not use up Acts.

Weathers

Type	Weather
Normal	Sunny Regular weather, no special effects A fine day with clear weather.
Cloudburst	Acid Rain Deals 20 Corrosion Damage to all Operators every second The rain pours down a mix of dangerous elements absorbed from the earth, sparing not even the steel and iron machinery.
	Thunderburst Lightning strikes 3 random tiles (range can overlap) every 30 seconds, dealing 1000 True damage to units on those tiles in an area Its said that lightning tends to strike unlucky people...
	Thunderstorm Lightning strikes 3 random tiles (range can overlap) every 15 seconds, dealing 1300 True damage to units on those tiles in an area Thunder and lightning flash right before your eyes. To go out at this time, are you perhaps testing your luck against the elements?
Heatwave	Hot Weather Operators are stunned for 10 Seconds every 50 Seconds Dizziness, blurred vision, confusion... the weather is too hot, please try to stay alert.
	Bright Sun Every 20 seconds, the Operator with the lowest Max HP is afflicted with [Burn] (does not stack), receiving 75 Arts damage per second for 10 seconds, and upon subsiding spreads the effect to any nearby Operators in adjacent tiles Prolonged exposure to sunlight makes the ground hot enough to fry eggs, so be careful not to get sunburned while outside!
	Scorching Sun Every 20 seconds, the Operator with the lowest Max HP is afflicted with [Burn] (does not stack), receiving 150 Arts damage per second for 10 seconds, and upon subsiding spreads the effect to any nearby Operators in adjacent tiles Weather that makes one wonder if this is what being baked feels like. If you stand outside for a while, you can feel your blood literally boiling.
Windblaze	Drought Redeployment Time +50% Staying dehydrated for too long will deplete everyone's energy.
	Sandstorm A sandstorm starts blowing in a random direction when the mission begins, and allied units caught in the sandstorm will have their ATK -35%. Facilities and other Operators can block the sandstorm to negate the effects. A storm in such a dry place makes sand and dust your biggest obstacle. Unless you have constructs or... someone else to cover you.
	Habūb A sandstorm starts blowing in a random direction when the mission begins, and allied units caught in the sandstorm will have their ATK -50%. Facilities and other Operators can block the sandstorm to negate the effects. Being caught in such a fierce gale full of sand will not just hinder your movements!
Addendum
Habūb or Haboob is a more intense sandstorm/duststorm. The Thunderburst/Thunderstorm lightning strikes have an area-of-effect of 2 tiles and will not affect Constructs. The Burn effect from Bright/Scorching Sun does not stack when the Burnt unit is affected again, but the duration will be refreshed. The Headquarters and Black Market will always be Sunny.

Outcome

Algorithm Completed	You successfully secured the headquarters. There's still a long way to go. At least 12 days have passed. The Lord Ameer's Attack is eliminated.
Algorithm Error	The headquarters has been lost. You are no more than a nameless grain of sand within the desert. The Base is destroyed during the Headquarters defense operation or the player quits out of it when all Acts have been used up. The campaign is abandoned.
Algorithm Aborted	You're still within your algorithm parameters. Survival must be ensured. Once Transregional Communication has been established, losing the campaign (Algorithm Error) will result in this outcome instead.
