Acrid is a playable character in Risk of Rain 2.

A macabre, poison-spewing ex-prisoner, Acrid fights with a potent array of damage-over-time effects and self-sustaining melee ability, as well as a mix of long-range and crowd control options for any situation. It also sports the highest base damage stat of any Survivor barring the Heretic, allowing for even greater damage potential.

Acrid's unique ability to inflict Poison or Blight status effects makes it an incredibly lethal choice when stacking items that inflict additional debuffs.

Tips

• Choosing between Poison and Blight is largely a personal preference.
  • Since Poison cannot stack, it favors a dodgier, fire-and-forget playstyle where the player poisons a group of enemies, leaves them to take damage, and finds some new enemies to poison in the meantime.
  • On the other hand, Blight favors an aggressive playstyle and rewards using more skills, as each Poisonous

Lore

Theoretically, the true contents of the cell were just a mess of atoms. The structure of the contents in each cell – living, weapon, whatever - was categorized, sequenced, and then turned to juice and cured into solid gems. An incredibly efficient and lossless format.

And yet when the cell containment broke – and emergency protocols re-sequenced that mess of atoms back into the creature known as Acrid – he already knew. Maybe he was somehow conscious, in his juice-gem state. Maybe they injected him with information. Maybe he was connected to their psionic network. Maybe he just made it up.

But he knew – that the strange crustaceans that scrambled his atoms and imprisoned him here, in a place unknown – were panicking. Something had gone wrong, in a world where variables were not allowed.

Something was leaking.

They may have finally imprisoned something that could not be contained.

Trivia

• The challenge necessary to unlock Acrid, "...To be left alone" is a reference to Acrid's victory screen from the first Risk of Rain, which reads "...And so it left, with a new hunger: to be left alone."
• Acrid is referred to internally as "Croco," and the Regenerative buff is referred to as "CrocoRegen."
• Acrid is commonly known as “Poison Doggo” as an internet meme.
• Instead of starting in an Escape Pod, Acrid starts asleep on the surface of the planet. During its wake up animation, it is actually vulnerable to enemy attack before the player is given control if its spawn location is particularly unlucky.
• Acrid originally fell onto Petrichor V, along with the majority of the UES Contact Light's cargo, locked inside of a crate that landed atop the area known as Sunken Tomb. It can be presumed that the Void Reavers managed to imprison it in the Void Fields between the events of Risk of Rain 1 and 2.
• Although Acrid somewhat resembles a Lemurian, it has been confirmed by developer Hopoo that it is not a Lemurian.
• Epidemic's enemy limit is completely unfeasible to reach under normal gameplay circumstances; since it spreads to 2 enemies at a time, up to 20 times, it can affect a total of 1 + 2^20 = 1048577 enemies. For comparison, the maximum number of monsters that can exist at once is 40.
