Frequently asked questions

What patcher does Randovania use?

Randovania supports the open source patcher MARS (Metroid Advance Randomizer System). This is a new patcher built from scratch and is unrelated to other Fusion Randomizers. Any differences from the vanilla game are covered under the differences tab.

Which versions of Fusion are supported?

Only the USA version of Fusion is supported with no current plans to support additional versions.

I saved in a place I can't get out of, am I softlocked?

You can use the “Warp to Start” function in the pause menu by pressing L and confirming. This will place you back at your start location with everything collected since your last save. Please note that this is never logical.

What is required to trigger and fight the SA-X?

To trigger the SA-X fight, you must have collected enough Infant Metroids and approach the Operations Room hatch. To fight the SA-X you will require Charge Beam and Missiles.
Reminder that the Operations Room hatch is now a grey Level 0 hatch.

How do the Missile Upgrades interact?

The missile upgrades functions have been split, allowing unique combinations of effects and damage.

  • Missile Launcher Data - Allows Samus to fire missiles causing 10 damage with no other upgrades
  • Super Missile Data - Adds 20 damage
  • Ice Missile Data - Adds the ability to freeze enemies with direct hits and adds 10 damage
  • Diffusion Missile Data - Adds the ability to charge a freezing blast and adds 5 damage

How do the Beam Upgrades interact?

The beam upgrades have been split, allowing unique combinations of effects and damage.

  • Charge Beam - Adds the ability to charge Samus’ beam
  • Wide Beam - Makes the beam fire 3 projectiles
  • Plasma Beam - Adds the ability to penetrate enemies
  • Wave Beam - Adds the ability to penetrate walls and makes the beam fire at least 2 projectiles
  • Ice Beam - Adds the ability to freeze enemies

    Each beam collected adds to the total damage dealt per projectile.

How do the Suit Upgrades interact?

The suit upgrades have been split, allowing unique combinations of effects and damage reduction.

  • Varia Suit - Adds protection from heated and cold rooms, and the ability to absorb Blue-X
  • Gravity Suit - Adds the ability to freely move in liquids

    Each suit collected provides additional damage reduction (amount depending on enemy type).
    Both suits are required for immunity to lava.
