The Timeless Child is a two-person co-op puzzle and mystery game that requires its players to communicate in order to solve puzzles and unravel the secrets behind them. The game has 22 achievements to collect between partners (including five hidden achievements) and will require communication, attention to detail, and more than one playthrough to get them all.

Achievements have always been a great way to extend a game's longevity, and the Timeless Child is no different. Even after completing the game and learning the puzzles, a replay can be used to scour each environment for hidden achievements that the players may have missed the first time around.

While some of the achievements in The Timeless Child are very simple to get, others will require time and patience. This is a game best played with either a dedicated achievement hunter or a very patient friend because some of these achievements are far from easy.
