Acrid is a returning character from Risk of Rain who made his way to Risk of Rain 2. Many characters will have complicated methods of unlocking them, and Acrid is no different.
When you load the game for the first time and check the challenges, you will see that you must pass the "... be alone" challenge to receive Acrid. There is a hint in the description telling you to stabilize the cell in empty fields.
To start this process, you need to go to the Bazaar Between Worlds, where you can visit the Lunar Shop. When you jump to the bottom of the row of platforms, look for a hole in the wall. Be careful on the way down as you have to go towards the green light which is quite a distance away. Choose your target platforms carefully, then give yourself time to heal before jumping again. There will be a portal at the end of the cave. When you go through the portal, a challenge starts that you must complete. Once this is done, you will now be able to play with Acrid.
There are beams of light in the air, emanating from purple knots. Go to the node and activate it, then take on the wave of enemies that appear nearby. At the end of each node, an element is dropped and you can move on to the next node. Just keep repeating the process until you are done with the realization.
