The Cyclone Street map is unlocked after reaching level 3. Until then, keep playing.

Enter the house, go straight forward into the kitchen, and from there into the basement entrance. If you look back, you should see a deer head on the wall.

While looking at the deer, say the following line out loud:


"I want to join the cult"


After this a red light should show up next to the head and you should get the Deerscent Into Madness achievement.

If nothing happens, try

• changing your game's language to English and making sure the game hears your microphone in the settings menu
  
• playing in singleplayer
  
• repeating the line as there is a short pause before the light turns red.

I've heard that sometimes stretching out "the" in "I want to join the cult" helps the game to recognize your voice better.

If you don't have access to a microphone, you can still get this achievement by using the game's text-to-speech feature.

Go up to the deer, press "P" (default hotkey for text-to-speech prompt) and type out the following:


"I want to join the cult"


This should give you the achievement if you weren't able to get it earlier.
