How To Unlock Millennium Labyrinth – Hyperdimension Neptunia Re;Birth1

Neptunia rebirth1 millennium labryinth neptune victoryHyperdimension Neptunia Re;Birth1 is a JRPG with an extremely grind heavy gameplay, and the difficulty spikes could go off the roof the moment you unlocked a new dungeon or go into coliseum battles. However if you’re already gone as far as Chapter 5, chances are you’re either used to (or masochistically enjoyed) other games with similar grinding intensive game mechanics, or the game’s cutesy anime charm and quirky storyline already got you hooked. More importantly, Chapter 5 will unlock plans for several new dungeons, one of which is Millennium Labyrinth.

Millennium Labyrinth GRINDFEST Part 1 – Hyperdimension Neptunia Re;Birth1 (PC)

Hyperdimension Neptunia Re;Birth1 (PC) playthrough: Millennium Labyrinth. For extensive information on treasures and enemies found in this dungeon, click “Show More”. Hyperdimension Neptunia Re;Birth1 is a remake of the first Hyperdimension Neptunia with overhauled gameplay and plot.


In the start of Chapter 5, look for Spelunker on the world map. Talking to him will unlock plans for the dungeon.

To add Millennium Labyrinth on the world map, you will need ONE (x1) item called “Magical Reactor 3”, which is dropped from Antares in Naasne Volcano (Add Enemies On).

Additional plans supported for this dungeon:
1. Add Enemies Plan – Obtained from Gramp Monster on world map in Chapter 5 or 6. Requires ONE (x1) “Magical Reactor 3”.
2. Item Change Plan – Obtained from Cat on world map in Chapter 5 or 6. Requires TWO (x2) “Phantom Wing” dropped from Fairy Fly in Millennium Labryinth.
3. Add Super Enemies Plan – Obtained from Chiba on world map in Chapter 5 after Noire rejoins you (Requires DLC). Requires ONE (x1) “Amazing Jelly” dropped from Clione in Millennium Labryinth.

Millennium Labyrinth GRINDFEST Part 2 – Hyperdimension Neptunia Re;Birth1 (PC)

Finishing up my grinding session in Millennium Labyrinth with two misleadingly adorable SP Attacks by Plutia. Hyperdimension Neptunia Re;Birth1 is a remake of the first Hyperdimension Neptunia with overhauled gameplay and plot.

2. Teratoxin (Plan)

Defeating Tank Type 99 (Tough Enemy) – Hyperdimension Neptunia Re;Birth1 (PC)

The Tank Type 99 is one of the tough enemies you’ll encounter in Millennium Labyrinth. It may drop an item called Megaton Shell once defeated. As long as you’re Level 80 and above while also having the right plans plus idea chips (anything that focuses on jacking up your EXE bar and heal you every turn will help tremendously), the fight should be only moderately difficult.

2. EDGE – Illegal RAM
3. Aimable – Rainbow Petal
4. Fairy Fly – Phantom Wing
5. Tank Type 99 – Megaton Shell
