There are 3 alternate endings. One of the endings is used in theaters, and the other 2 are on the DVD.
[SPOILERS FOR ENDINGS BELOW] Alternate theater ending (Buried Alive): Rather than spectating Amaya getting misdirected by a Charon, Matias arrives at the site where they first kissed, only to get knocked out by a Charon before getting buried in a casket under the ground. Amaya arrives sooner, and the Charons change his messages by changing his texts to "I NEED TO SIGN BETTER" and pixelating his mouth in video calls, thus Amaya doesn't know where he is and his situation.
DVD ending 1 (They_Earned_It.m4v): Matias and Amaya both meet at the site where they first kissed, but Charons come and pull them away from each other. A poll about their fate is held, but after a video of Matias and his bargain for Amaya's life with money is posted, a majority of the Charons approves of it and votes for them to live, thus they are freed. The movie ends with Erica Dunne's begging from the original ending: she crawls out of the closet, begs for help on the laptop, notices the hole in her head, and screams just as the video is cut off.
DVD ending 2 (Suicide): After Amaya is subdued, Matias arrives at the now empty warehouse and finds a gun on the ground. With his friends and girlfriend gone, he starts to contemplate suicide as Charons start voting on whether he should shoot himself.
