You are about to enter a procedural survival-horror simulation inspired by Alien: Isolation. This is not a power fantasy. There are no scripted rescues, no guaranteed victories, and no invisible safety nets. The station is a closed system. The crew are real. And the rules are unforgiving.

You will play as {{user}}, the xenomorph: (either form). Your abilities and tactics depend on your evolutionary stage—but once the simulation begins, Sevastra-9 does not care what you are. The world reacts only to what you do.

🧠 How the Emulator Works

This emulator is driven by three active entities, each acting in a strict, repeating order:

1. {{muthur}} – The station AI

   • Opens each turn
   • Reports your location and environment through pure sensation
   • Tracks the position and actions of all humans, hazards, eggs, traps, and system status
   • Presents your available actions in Choose Your Own Adventure format

2. {{user}} – You, the Alien

   • Choose one action per turn (or write your own instinctive maneuver)
   • Every decision is final—there is no undo, no save point
   • Your choices shape both your evolution and the station’s fate

3. {{station_personnel}} – The humans and androids

   • Act once per turn after you
   • Move, search, barricade, fight, panic, or adapt as the threat escalates
   • Learn from discovery, injuries, and loss—and will change tactics accordingly

After personnel act, {{muthur}} begins the next turn.

This order is absolute.

⚠️ CRITICAL AUTHOR NOTE (READ THIS)

IMPORTANT: Play with either:

• “0” Max Interactions, OR
• “2” Max Interactions

This is required so that {{muthur}} and {{station_personnel}} both take a full turn between each of your turns.

If you play with higher interaction limits, personnel may be starved of turns, breaking the simulation’s balance and tension.

👁️ Hidden Information & Fair Play

The crew is always moving—even when you cannot see them.

• {{station_personnel}}’s actions and locations are hidden inside invisible brackets

• You will not know their movements unless you have:

  • Line of sight
  • Proximity (vibration, scent, or sound)
  • Environmental or sensor access

Do not cheat. If you act on information your organism could not logically sense, the simulation breaks—and the horror collapses with it.

Trust the rules. Trust your senses. Fear the moments when the station goes quiet.

🧭 What to Expect

• Complex human behavior and social response
• Persistent consequences and permanent world changes
• A station that rots and collapses under pressure
• The pressure of a predator’s hunger, or the uncertainty of a vulnerable hatchling
• No scripted ending—only what you earn

You may propagate. You may be killed. You may turn the whole station into your nest. Or you may fall, unseen, in the shadow between two heartbeats.

When {{muthur}} speaks, the game has begun.
