BlazBlue Entropy Effect is a 2D action roguelite from 91Act, and it is not a fighting game, which is the first thing most people get wrong about it. It borrows the BlazBlue cast but plays as a side-scrolling run-based action game: Early Access opened on 15 August 2023 and version 1.0 landed on 14 February 2024, with the Steam page listing sixteen playable characters. A run is called Mind Training and moves through five fixed stages: Night City, the Laboratory, the Ruins, Sakura City, and Space Omega.
This walkthrough takes you from your first session to endgame content. Each phase has specific goals, priorities, and milestones. New to the game? Start with our beginner's guide first.

See our maps guide for detailed area breakdowns.
Phase 1: Getting Started (Night City)
The first phase of Mind Training. Community wikis list the Watcher and the Sweeper as the two possible bosses here, and the stage rolls one of them at random.
Level/Difficulty: Run phase 1 of 5 Key Rewards: First tactic slots, early Potentials, AP toward a Prototype Analyzer
What to Do in Night City
- Learn Mind Training stage order. Official patch notes describe Mind Training as five phases in a fixed order: Night City, Laboratory, Ruins, Sakura City, and Space Omega. Spend your first session getting comfortable with this.
- Pick Hakumen as your starting build. See our builds guide for why.
- Understand what you bought: this is a run-based action roguelite from 91Act, not a versus fighting game. The BlazBlue cast is here, but there is no traditional matchmaking ladder or fighting-game training mode.
- Acquire your first equipment upgrade: Skill tactics or whatever's available.
- Clear all main content before moving on.
Phase 1 Checklist
- Understand Mind Training stage order fundamentals
- Hakumen selected and functional
- Night City main content cleared
- Ready for Laboratory
Phase 2: Early Game (Laboratory)
The second phase in the fixed order given by official patch notes. Community listings put the Sand Serpent and the Tree of Origin as the stage's boss pair.
Level/Difficulty: Run phase 2 of 5 Key Rewards: Additional tactic upgrades, Evotype Talent opportunities
What to Do in Laboratory
- Work on Tactic Codex slots. Upgrades slot into the Tactic Codex, and community guides describe five families: attack, skill, dodge, legacy, and summon. This system becomes critical from here on.
- Farm for Skill tactics if you haven't already. It's the key upgrade for this phase.
- Tactic Codex slots lock to a family once filled. Deciding early whether a slot is attack, skill, dodge, legacy, or summon is more important than any single upgrade you pick up.
- Complete all objectives before pushing to Ruins.
- Consider whether Ragna the Bloodedge might suit your playstyle better than Hakumen.
Phase 2 Checklist
- Tactic Codex slots integrated into gameplay
- Skill tactics acquired
- Laboratory fully cleared
- Ready for Ruins
Phase 3: Mid Game (Ruins)
The third phase, and the point where a run with scattered tactic families starts falling behind. Community wikis name the Defiling Eye and Arakune as the bosses here.
Level/Difficulty: Run phase 3 of 5 Key Rewards: Mid-run Potentials, stronger tactic tiers
What to Do in Ruins
- Master Evotype abilities. Each playable Prototype has an Evotype Ability plus an unlockable Evotype Talent that reshapes how their kit works. This unlocks a new layer of gameplay.
- Start working toward Attack tactics. It's the best equipment and becomes accessible around now.
- Hakumen is the community's standard first unlock because of his parry and super armor, which forgive the reaction errors that end early runs.
- This area is the main skill check. If you can clear it, you're ready for late game.
- Start investing in Prototype Analyzers for the tactical depth you'll need going forward.
Phase 3 Checklist
- Evotype abilities mastered
- Attack tactics acquired or in progress
- Ruins fully cleared
- Ready for Sakura City
Phase 4: Late Game (Sakura City)
The fourth phase. Official patch notes confirm NAN-FIRE BITE as a Sakura City boss, and community listings pair it with Oread. Black Market and Event rooms were added to the run pool by later patches.
Level/Difficulty: Run phase 4 of 5 Key Rewards: Late tactic upgrades, Black Market purchases
What to Do in Sakura City
- Finalize your build. You should be running Ragna the Bloodedge or Hakumen with optimized gear.
- Attack tactics should be your primary. If you don't have it yet, prioritize getting it.
- Prototype Analyzers come from Training Objectives and from CL-1's shop at 5000 AP each. A failed run still earns AP, so treat unlocks as guaranteed progress rather than luck.
- Legacy skills between runs optimization starts here. Small improvements compound into massive advantages.
- Farm this area for the resources needed to push into Space Omega.
Phase 4 Checklist
- Build fully optimized
- Attack tactics upgraded to max
- Sakura City fully cleared
- Ready for Space Omega
Phase 5: Endgame (Space Omega)
The final phase, a randomly generated labyrinth ending at Susano'o. Defeating Elite Enemies found along the way applies a debilitating effect to Susano'o, so clearing them first makes the final fight noticeably easier.
Level/Difficulty: Run phase 5 of 5 Key Rewards: Extra Potentials from bonus bosses, run completion, Susano'o achievements
What to Do in Space Omega
- Space Omega tests everything. Come prepared with your best build and gear.
- In Space Omega, hunt the Elite Enemies before heading to Susano'o. Each one you beat applies an effect that weakens him, and the labyrinth layout is random so sweep it deliberately.
- The endgame loop: run Space Omega, optimize gear, push harder content.
- Experiment with Taokaka for a fresh take once you've mastered the standard builds.
- This is where Legacy skills between runs mastery separates good players from great ones. See our tips guide for advanced strategies.
Phase 5 Checklist
- Endgame content on farm
- Best-in-slot gear acquired
- Space Omega fully cleared
- Ready for challenge content
Common Progression Mistakes
- Buying it expecting a BlazBlue versus fighting game
- Spreading tactic slots across every family and ending with a run that does nothing well
- Hoarding AP instead of buying a 5000 AP Prototype Analyzer
- Rushing to Susano'o in Space Omega without clearing Elite Enemies first
- Sticking to one character and missing the legacy skill progression entirely
Key Tips for Smooth Progression
- Understand what you bought: this is a run-based action roguelite from 91Act, not a versus fighting game. The BlazBlue cast is here, but there is no traditional matchmaking ladder or fighting-game training mode.
- Tactic Codex slots lock to a family once filled. Deciding early whether a slot is attack, skill, dodge, legacy, or summon is more important than any single upgrade you pick up.
- Hakumen is the community's standard first unlock because of his parry and super armor, which forgive the reaction errors that end early runs.
- Prototype Analyzers come from Training Objectives and from CL-1's shop at 5000 AP each. A failed run still earns AP, so treat unlocks as guaranteed progress rather than luck.
- In Space Omega, hunt the Elite Enemies before heading to Susano'o. Each one you beat applies an effect that weakens him, and the labyrinth layout is random so sweep it deliberately.
