Phantasy Star II/Shure

As the game begins, our main hero Rolf finds himself in the city of Paseo, the capital of Mota with a mission to retrieve the recorder from the Biosystems Lab to understand why the planet has been overrun by dangerous biomonsters. He returns to his house and gets his trusty friend Nei, a mutant who is an effective fighter and healer.

Paseo
When you gain control head to the upper right and enter the weapon shop. Purchase 2x Steel Bar and then leave. Equip them to Nei. She can now attack twice. Now it is time to level up.

Go outside and walk around the grass area (do not enter the tunnel to the north yet) and fight until either character's HP reaches 5, then press to stop fighting and select STGY, and use Nei's Res tech to heal them back to full. Continue fighting until Nei runs out of TP, then go back into the town to the lower left and enter the Hospital. Spend 16 meseta there to heal HP and restore TP. Leave the hospital and head north and save your game. Then leave Paseo and repeatedly hunt biohazards until Rolf reaches level 5 and you can purchase and equip another Knife (100m), Headgear (120m), and Fibercoat (300m). Ignore the other items here as they cannot be equipped by Rolf or Nei.

When ready head north through the tunnel, then north across the bridge (ignore the tunnel on the left for now), east past the forest, south across another bridge, southeast around a forest, and then into Arima.

Arima
Talk to everyone in town. Fight until you have 1200m and purchase Rolf a Sword. Then head back to Paseo and enter Rolf's house to meet the Biomonster hunter named Rudolf Steiner, nickname Rudo. Select Reorganize and add Rudo to your party. Then change your party order so Rudo is in front because he has the highest defense and HP.

It is time to level up Rudo. Head back to Arima and then across the bridge to the east to face harder monsters.
