Dead Island: Riptide Definitive Edition

For this you need to play trough the game which is obviously quite self explaining. You know you've reached the end of the game after defeating Harlow in the lab and from there on going to the boat. After you enter the boat, a short cutscene will play - the game is over and the achievement should pop now.

Keep in mind: once you've entered the boat you can't go back, which means you won't be able to finish your quests or collect some other achievements.
