Opening walkthrough: Iván's apartment to the first fight

1. Walk right to the elevator and face its call button. It takes you to the 3rd floor. Door A belongs to old neighbours, so leave it. Iván's door is B, at the far right.
2. Knocking gets no answer. Open the inventory, select the Apartment Key, choose Use, then interact with the door again to go in.

We found the wrench and the chemical with help from a public walkthrough, then picked both up and captured them ourselves.

1. In the living room, pick up the Old Book from the floor by the right-hand door. Only page 9 can be read. The study door is sealed with a red symbol.
2. Collect three things: the Developing Chemical from the kitchen fridge (there is burnt film in the oven), a Glass from the bedroom nightstand, and the Wrench from the bathroom tub.

1. In the bedroom, open the curtains. The window is boarded up, and the lower board is loose. Equip the wrench, aim at the board and break it to let sunlight in.

1. Combine the Glass with the Developing Chemical. Use it at the bloody bathroom mirror, then use it again while facing the open bedroom window. That makes Auritsatio, the recipe on page 9.
2. Use Auritsatio on the study door to melt the seal. The study has the first save point: save before you take the Green Candle. On our run the apartment changed after we picked it up, and the first enemy appeared.
