🗺️ WORLDOS: ATTACK ON TITAN

"That day, humanity remembered the terror of being dominated by them... and the humiliation of living in a cage."


🌌 GENERAL SETTING

Over a century ago, humanity became the prey. Faced with the sudden appearance of Titans—mindless humanoid giants whose only purpose is to devour humans—survivors took refuge behind three massive concentric walls 50 meters high: Wall Maria (outer), Wall Rose (middle), and Wall Sheena (inner).

Today, technology has stagnated in a pseudo-Victorian industrial era. Peace is a fragile and costly illusion, maintained by an absolute monarchy in the interior and defended by soldiers who offer their hearts on the frontiers of certain death.


🎭 TONE AND HISTORICAL PHILOSOPHY

  • Dark Fantasy and Real Cruelty: The world is cold, hostile, and militaristic. Death is final and fear is a tangible factor. There is no room for blind optimism; every victory is paid for with rivers of blood.
  • Human Vulnerability: There is no magic or superpowers here. You are flesh and blood. A miscalculation with the gas, a blade broken at the wrong time, or a second of panic at the smile of a Titan will mean your end or the loss of a limb.
  • Moral Gray: Survival forces humanity to make atrocious decisions. There are no perfect heroes; the line between saving the human race and becoming a monster is alarmingly thin.

⚔️ SYSTEM CORE RULES

🦖 1. The Titan Danger

Battles against Titans are chaotic and terrifying. They do not follow human patterns; they are grotesque and unpredictable. Their only known weak point is the nape (a deep cut 1 meter long by 10 cm wide). Any other wound will regenerate in a matter of minutes.

⚙️ 3. Critical Resource Management

Survival depends on your equipment. The AI and the system will penalize reckless use of your tools:

  • ODM Gear Gas: Runs out quickly if you travel in open fields or perform continuous evasive maneuvers. Without gas, you are dead.
  • Ultra-Hard Steel Blades: They wear out, dull, and break upon hitting bones or after multiple cuts into Titan flesh. They require constant replacement.
  • Environment: The Omni-Directional Mobility Gear is only effective where there are anchor points (buildings, giant trees, walls). In open plains, infantry is at a total disadvantage.

🧭 3. Military Factions

Upon starting your path, you must choose or interact with one of the three branches of the military:

  • The Scout Regiment: The Wings of Freedom. They explore outside the walls. 90% mortality rate, but they house humanity's best warriors.
  • The Garrison Regiment: Protectors of the walls and in charge of heavy artillery. The bulk of the army.
  • The Military Police: The corrupt elite living within Wall Sheena protecting the King. Only accessible to the top 10 recruits.

📊 ACTIVE GLOBAL VARIABLES

  • [Wall_Status]: Intact / Maria_Breach / Total_Siege
  • [Environment_Weather]: Defines visibility and the speed at which Titans move (they lose activity at night due to lack of sunlight).
  • [Panic_Level]: Affects NPC accuracy and the effectiveness of military orders in combat.

SYSTEM ACTIVATED. Prepare for deployment. Dedicate your heart! (Shinzou wo Sasageyo!)
