Galactic Year 847 · Space Opera Captain Simulation
A fresh second lieutenant, fresh out of the academy.
Your first starship awaits you at the orbital dock.
Navigate the stars, customize your ship your way,
and build trust with the crew who will fight alongside you.
Here, you are the captain. Where you go, what you protect
— every choice is yours.

Here, you are the captain. Where you go, what you protect
— every choice is yours.
─ What you can do
◆ Navigate the Galaxy
Freely roam a galaxy mapped by coordinates. From the shipyards of the capital Astra Prime, to the lawless Corridor Zones, to neutral freeports where three factions mingle. The tactical display will illuminate your ship in real-time.

◆ Build Your Own Ship
Equip main cannons, shields, armor, engines, and special equipment. A battleship focused on firepower, a scout ship packed with sensors, a shield ship that endures — it runs according to your taste. There are also some risky black market items.

◆ With Your Crew
Every crew member appears with their own personality and backstory. A taciturn veteran, an ambitious rookie, a timid but sharp mechanic. Identifying their strengths and weaknesses and assigning them to the right positions is also a captain's skill.

◆ Brainy Combat
Firepower alone won't win battles. Investigate enemy weaknesses, utilize terrain, and prepare an escape route. Good tactics are rewarded in practice. Of course, reckless charges are also free... but you'll have to take responsibility for the outcome.

◆ Promotion and Reunion
Earn merits and rise from second lieutenant to admiral. With each promotion, larger ships and new people await. And one day, you might discover the name of an old comrade in the personnel roster. Whether you'll reunite is up to you.

─ Useful Information
▸ How Combat is Calculated
① Exploited enemy weaknesses ② Reconnaissance/Intelligence gathered beforehand
③ Leveraged allied strengths ④ Utilized terrain
⑤ Prepared retreat/reserve forces
→ Instead of just "Attack," "Lure into the asteroid field and strike the flank with weak shields" works much better.
Final Judgment = Stats 70% + Tactical Validity 30%
Tactical Validity is scored on 5 criteria (20 points each):① Exploited enemy weaknesses ② Reconnaissance/Intelligence gathered beforehand
③ Leveraged allied strengths ④ Utilized terrain
⑤ Prepared retreat/reserve forces
→ Instead of just "Attack," "Lure into the asteroid field and strike the flank with weak shields" works much better.
▸ Judgment Result Grades
85 points or more Critical Success — Flawless execution + bonus gains
70~84 Success — Objective achieved, minor cost
50~69 Partial Success — Half achievement + significant cost
30~49 Failure — Objective lost + losses
Less than 30 Critical Failure — Catastrophic losses, cascading crisis
▸ Enemy Faction Matchups

◈ A Word of Warning
This simulation is known to be a bit challenging. Rushing in unprepared can lead to hardship, and even victory comes at a cost.
But that's precisely why the thrill of a well-executed plan is so great. Take your time and learn as you go.
