Clash of Steel (Merciless)

Clash of Steel (Merciless) is one of the possible follow-up stages that the player can access after completing An Elder Secret (Merciless), the first stage in Growing Strange. Completing this stage yields an Elder Catfruit Seed, with a very small chance of an Elder Catfruit. This stage is based around Metal Enemies.
