Eric can succeed or fail the QTEs to get the achievement. At the end of Semper Fi, Rachel will attack the group (kinda like what Clarice usually does in this scenario).
Disagree with this plan and pass the QTE so Rachel can run away.
Salim will talk about the corpse and the rejuvenating goop in the cocoon. Rachel gets bitten and infected during The Horror, but that’s okay. Ensure that Rachel and Eric remain alive for a while. Until Death Do Us Part – Rachel gets infected and she kills Eric, or Eric kills her. When the mid-credits scene plays, you’re told that Rachel was left behind and her body was never found. In the next chapters/finale, ensure that your other teammates die. Otherwise, he’ll use the UV wand to make the parasite leave Rachel’s body. Again, Eric has to be dead before this point. Agree to this plan and the group will place Rachel inside the cocoon. Avoid dialogue options that will get her killed. In Strange Aeons, Rachel will scream in pain due to the parasite. In The City, have Jason examine the mummified corpse that’s still alive. Ensure that Rachel remains alive she’ll get bitten and infected during The Horror, but that’s okay. Ensure that Eric is dead before you reach the Strange Aeons chapter. This House of Ashes achievement is a bit more complicated: Lost In Time – Rachel wasn’t rescued and she remains trapped in the cocoon. But, if relations are too low, she’ll dump both of them. During The Ancient One, Rachel will choose either Eric or Nick. Whenever you control these characters, make sure that you pick the negative/hostile/mean responses. Rachel, Eric, and Nick are in a love triangle. Climbing Out of Hell – Rachel survives after rejecting both her lovers. Because there’s no air support after the Daylight finale, Salim will walk away without being captured. Continue the campaign and make sure that Salim stays alive. Do not call for air support during The Briefing and ensure that Merwin dies early (he must not repair the radio). Into the Sunset – Salim returned home to his son. What I can say is that I didn’t get this achievement when I intentionally killed the rest and only kept Salim alive. Final Girl – Have only one survivor at the end of the game.I can’t confirm if this has to be Rachel. You can either fail the QTEs against the vampires or fail the QTEs against Balathu/Kurum if he’s still around (this will cause the vampires to automatically kill the other characters). Six Minutes of Night – Everyone died in the finale.
Golden Path – All five main characters survived the finale.
