The Survivors of the Void expansion for Risk of Rain 2 is out now. Not many players know that there is an alternative hidden final stage at the end of the story known as "The Planetarium" and a challenge "Escape The Planetarium". How to get there and and how to escape are two separate problems you'll have to solve and survive in real time.

Our guide will answer the questions of how to escape Planetarium in Risk of Rain 2, and help you find your way in and out. This final stage of the game involves not only platforming, but also a boss fight with the Voidling.

Risk of Rain 2: How to Escape Planetarium

You're going to need to enter a Purple Portal to make your way through the Void Fields and get to the Planetarium.

There is a Purple Portal to be found in the Bazaar Between Time, in a tunnel underneath the Blue Portal within the Bazaar. It's not your only option to encounter a Purple Portal, though.

A Purple Portal may spawn after you clear a teleporter event. Some say this only happens on loop, but it is truly random. I've encountered one Purple Portal pre-loop, but.. only one.

Alternatively, and strangely enough, you can also get a Purple Portal by killing Mithrix and petting a purple frog at the start of the stage. This is the most effort-intensive option and requires 10 Lunar Coins to do. Simply kill Mithrix and run back to the start of the stage as you would otherwise, and pet the frog instead of charging your ship.

Enter the Void Locus

You should make sure to have some recovery items before attempting this.

In order to enter the Void Locus, you need to follow these steps:

  1. Breach all nine cells in the Void Fields
  2. Fight all enemy waves
  3. Approach the Null Portal
  4. Wait for the Void Portal to open next to it
  5. Choose the Void Locus realm

Once, you're inside the Void Locus, you will get the chance to finally enter The Planetarium, if you do the following:

  1. Activate all four Deep Void Signals (similar to Void Fields cells)
  2. Fight all enemy waves
  3. Wait for another Void Portal to spawn at the top level of Void Locus
  4. Enter the portal to the Planetarium

Defeat the Voidling

Now players can finally fight the alternate boss Voidling and escape Planetarium. Here are a few tips on how to defeat him:

  • Use your sniper rifle to aim at his eye for maximum damage
  • You can easily dodge his projectiles, as they're quite slow
  • Look out for a cover, once he shoots his laser
  • If you see him rotating, take cover, since an even larger laser shot coming in
  • Also take cover, once he activates his Black Hole that sucks everything in

There are three phases in total, at the end of each you need to go through portals and finish platforming stages. You will also encounter some imps and lemurians that you need to fight off. But other than that, all phases follow the same pattern.

Once you enter the final portal after defeating Voidling, the "Escape the Planetarium" challenge will be complete.
