ABOUT

What is Risk of Rain 2?

A 3D roguelite shooter in which you battle hordes of monsters to escape an unfamiliar planet. Its defining feature is that **time itself drives the difficulty**. As the on-screen timer advances, enemies become stronger and more numerous. Take your time collecting items and preparing, and the situation can spiral out of control. Meanwhile, stacking copies of items adds to their effects, potentially giving you absurd power that can clear the screen in a single hit late in a run. The pull between rushing and collecting is the core of the game. Play solo or in co-op with up to four players. The source's August 2026 Steam snapshot records over 350,000 reviews and a Very Positive rating. Japanese is supported.

Three Conditions for Finishing a Stage

Difficulty rises with time, so decide where to explore and move with a purpose. There is no universal rule that finishing within a certain number of minutes is always correct.

  1. On entering a stage, look for particles around the teleporter and its distinctive pillars. Avoid chasing enemies back and forth over the same ground.
  2. Use nearby chests and interactables to improve mobility, healing and damage. Some nearby interactables become unavailable after activation, so check anything you plan to use first.
  3. Activate the teleporter and deal with the boss and other enemies that appear. You must remain inside the red area to charge it, but leave temporarily to avoid a lethal attack.
  4. Normally, charging stops at 99% while the boss remains alive. Defeating the teleporter boss is also required to reach 100%.
  5. Confirm that charging is complete and the boss is defeated, then collect the reward. Decide whether to open any remaining chests or move to the next stage.

90% is not the normal point where charging stops. Distinguish between charging pausing outside the area and stopping at 99% while the boss remains alive.

Choose Items by Their Role

Expect random drops and cover the roles you lack. Do not treat DLC-only items as essential base-game equipment.

Choose Items by Their Role:6 entries
Role You LackBase-Game ExamplesCaution
MobilityPaul’s Goat Hoof、Energy DrinkCheck the difference between walking and sprinting. Give yourself room to avoid attacks in the final fight
Sustained damageSoldier’s Syringe、Tri-Tip DaggerJudge the effect on a Survivor whose attack speed or hit frequency suits it
Clearing nearby enemiesUkulele、GasolineAn effect that clears groups may work differently against a single boss
HealingCautious Slug、MedkitConditional effects. These items do not provide endless healing while you keep taking hits
Making use of equipmentFuel CellCheck the equipment's own effect, charges and cooldown
Exchanging unwanted itemsScrapper and 3D PrinterCheck the scrap color and exchange target before interacting. Avoid losing items you still need

Lunar items also have drawbacks. Do not take one without reading its effects just because it is rare. The way effects scale with stacks also differs by item.

Stage 5: Go to the Moon or Loop

Sky Meadow in the base game contains the Primordial Teleporter. Check its outer ring and destination message before activating the center.

Stage 5: Go to the Moon or Loop:4 entries
ChoiceAction and ResultWhen to Choose It
Go to the moonActivate and complete the Primordial Teleporter while it is aligned with the moonYou have the damage, mobility and healing to face Mithrix
Continue loopingInteract with the outer ring before activation to align it with the planetYou want to gather more equipment or pursue later unlocks
Enter a different portalCheck any portal that appears before using itIts destination differs from the central teleporter's route to the moon
Prevent an accidental choiceTreat interacting with the outer ring and activating the center as separate actionsRead the message before activation; do not try to change it during the fight

Reaching the Final Fight in Commencement

Reaching the moon does not complete the run. Make your way to the summit while staying prepared for the fight.

  1. Proceed from the entrance to the different areas and charge the required pillars. The charging areas and hazards vary, so watch your health as you enter each one.
  2. Once the required charging is complete, use the means of reaching the summit. Do not stay on the ground waiting for the boss to appear by itself.
  3. Mithrix has a phase that steals your items, so avoid relying entirely on items for movement and attacks. Check your Survivor's own escape abilities.
  4. Learn the route back before entering the fight. You will ultimately need to reach the rescue ship and complete the escape.

Mithrix's Four Phases and How to Respond

Use changes in appearance and behavior as cues instead of assuming attacks occur at fixed intervals.

Wide tables scroll horizontally.

Mithrix's Four Phases and How to Respond:4 entries
PhaseChangeResponse
Phase 1Fight Mithrix himself as he uses hammer and needle attacksKeep your distance and move away from the hammer's landing point after his dash. Strafe out of the needles' line of fire
Phase 2Mithrix withdraws and you fight Lunar ChimerasDefeat all airborne and ground enemies. Do not fix your attention on the ground enemies alone
Phase 3Mithrix returns with stronger hammer and wide-area attacksWatch for gaps in the rotating attack and move through them. Do not assume its reach is as narrow as in the earlier fight
Phase 4He steals the player's itemsDo not charge in expecting the strength you had before the theft. Keep your distance and attack to recover your items

Certain equipment or very high damage can skip phases, but a standard beginner approach should not depend on doing so.

Escaping After the Fight and Identifying Why You Failed

Check defeating Mithrix and completing the escape separately. The escape is required to win the run.

  1. After defeating Mithrix, use the exits that appear to return from the arena. Do not remain there waiting for a victory sequence.
  2. Head to the rescue ship within the time limit. Prioritize the escape route over detours to find remaining interactables.
  3. Stay in the ship's area to charge it, avoiding enemy attacks until you complete the escape. Simply touching the ship does not finish the run.
  4. If you fail, identify whether the problem was insufficient exploration, poor preparation for the moon, the boss's fourth phase or losing your way back. Choose one objective for the next run.
FAQ

Risk of Rain 2 FAQ

Before activation, the Primordial Teleporter's outer ring lets you switch between the moon and the planet. Check the message before activating the center.

You must also escape the moon. After the fight, return to the rescue ship and finish charging it within the time limit.
