The game will play out in a semi-linear fashion using the "string of pearls" model that was common at Sierra in the early days. At the beginning of each chapter, there are many different tasks that can be solved in any order. When all tasks are solved, the end of the chapter will be triggered.

The puzzles will be quite classic, as inventory and logic puzzles will represent the main challenge of the adventure. The difficulty will be modest, so that genre newcomers should have a chance, too. There won't be any hard puzzles right at the beginning of the game, Jensen said, but there will be more complex puzzles later on, fully integrated into the storyline so that players will be motivated instead of discouraged. Thankfully, there won't be any gameplay annoyances like pixelhunting in Gray Matter.

Along with the puzzles, there will also be some minigames for the unique abilities of Sam and David that can be controlled via special menus. Sam can do several magic tricks while the neurobiologist is able to perform hypnosis. If there will be death sequences in the game, they will only occur in the finale.
