Lava Infected Walls are hazards in Final Ninja 2.0: Legacy. They are a special type of wall. If Takeshi comes into contact with one, he will lose a third of his health. However, if Takeshi fires a rope into them, the rope will slowly turn orange. When the rope is completely orange and reaches Takeshi, the rope will dissolve, and 1/3 of Takeshi's health will be depleted.
