Your name is Alyssa and you're an agent working for the API. Your mission is to infiltrate a Lab on the planet Rhomu and retrieve the strange technology. Upon your return, you learn from your team what the technology can actually do, and decide to steal it and hide it from the API.

Welcome to Cosmic Star Heroine, a cyberpunk J-RPG set in a dystopian future. The game presents itself as classic J-RPG like the sort you would remember playing on your Super Nintendo. The art direction and sound is taken right out of the 90's and also features turn based combat like the earlier Final Fantasy and Chrono Trigger games. If you are a fan of J-RPGs, you will love this game.

Before You Begin ~ a Note on Missable Trophies!

The MISSABLE trophies are not very missable. Because there is no free roam post game, you could technically miss all that are not story related. I have listed the trophies in order of obtainment, so as long as you follow the guide, and make a backup save after the asteroid mission you will miss none of them. The only one you can miss is Product Placement and this is earned in the first 15 minutes of play, so if you do happen to miss it, you will be able to earn it really fast.


Step 1 ~ Prepare to Die Trophy

For Step one you will want to set the difficulty to the highest and complete the first battle. You will not need to play beyond the first fight in this difficulty so you can restart the game and set it to what ever you feel comfortable with.

Upon completing this step will earn you the following trophies:

  • Prepare to Die

Step 2 ~ Play the Game (until after the asteroid mission)

There really is not a lot to this game. Just set your difficulty and play the game. You will need to stop after the asteroid mission. The game will tell you to make a back up save before this mission, and I recommend doing it as well.

Upon completing this step you will have earned the following trophies:

  • Bomb Squad
  • It's baaaack!
  • Rogue Agent
  • Safehouse
  • Kaiju Killer
  • Captain
  • Prison Break
  • Visionary
  • Crystals
  • Objection!
  • Full House
  • Betrayal
  • Practice Makes Perfect MISSABLE
  • Product Placement MISSABLE
  • Stylish MISSABLE
  • Rat Pack MISSABLE
  • Charming MISSABLE
  • Teamwork MISSABLE
  • Friendship MISSABLE
  • Red Button MISSABLE
  • Gourmet MISSABLE
  • Overkill MISSABLE

Step 3 ~ Optional Bosses

Before heading out to the final mission, it is time to take care of a few optional bosses and quests. These bosses have a lot of HP, so make sure you have checked equipment and abilities before you begin. You may want to give Alyssa her revive ability just in case someone does die.

Upon completing this step you will have earned the following trophies:

  • Crowded MISSABLE
  • Gunmancer MISSABLE
  • Braaaains! MISSABLE
  • Mad Skills MISSABLE
  • Dem Bones MISSABLE
  • Eldritch Master MISSABLE
  • Primer MISSABLE
  • Scavenger MISSABLE

Step 4 ~ Complete the Final Mission

With step three out of the way, go ahead and finish the final mission.

Upon completing this step you will have earned the following trophies:

  • Cosmic Star
  • Heroine

34 trophies ( 10  19  1  )

  • Achieve all possible trophies.


  • Complete the game.

    Story related and cannot be missed

    The final level of the game takes place on an alien spaceship. It is a pretty short level but longer than most others you have come across, and you will not find it very challenging to get through at this point.

    To beat the level, you have to complete four boss fights in a row. The first boss fight takes place against Echo and is pretty standard. The remaining three are against the Lumina device itself.

    The first fight with the Lumina Device is simple and straight forward. Attack the only part you can until you drain it of its HP.

    The second fight grants the Lumina Device three attachable points, two guns and a head unit. For this fight, I would cast a song to damage all three parts each round then focus on each of the guns and finally the head unit.

    The third fight once again sees the Lumina Device granted 3 points to attack, two tank like monsters and a third head unit. This time round, cast a song to cause damage each round but only focus on the head unit. When it dies, so do the two support mobs.

    After this fight the trophy will pop, and so will the . You do not need to watch the end or the credits, but you can if you like.
