The Alters is a game that may seem quite compact, but in reality it is filled with a large amount of main and optional content. Our guide will provide you with detailed information about the game's length. We answer the question of how long it takes to complete the game and whether you can spend more time on it thanks to collectibles, alternative endings, and optional missions. This is useful knowledge in terms of completing The Alters in 100% and getting the platinum trophy.

Main story missions

  1. The campaign of The Alters consists of a prologue and three extensive acts. Depending on your play style, you should finish it in about 70 days according to the game's calendar (the game displays the current number at the beginning of each day).
  2. A typical first playthrough should take you about 25 hours. This result is primarily influenced by the chosen difficulty level, replaying days (e.g. to avoid making mistakes) and how you want to spend the following days. You can fully utilize working hours and have long conversations with alters and spend your free time with them.

Collectibles, other endings and side tasks

  1. You cannot discover everything in a single playthrough. You won't be able to create all available alters, nor see all endings. This may be a reason to replay the campaign - completely from scratch or from an important choice in act 2, which will affect the availability of endings and relationships with alters.
  2. A detailed exploration of the planet and getting all the collectibles, as well as dealing with side missions, can keep you playing for a while. Some of them may require certain preparations, such as expanding the base or gathering more resources. Expect that the optional content will extend the game time by at least 5 hours.
  3. The platinum trophy will also require a few playthroughs. This is the only way to unlock achievements associated with, among others, all lessons, alters, and various endings.
