 This mode allows the player to replay the Adventure mode, which was impossible in the prequel without creating a new save file.The player can choose any of the three books to play through; Lex is leveled down equivalently to what he should be at the chapter, and the player must keep Lex alive or otherwise receive a game over.Instead of the level up bar at the top-left, the player can find the score bar; Lex levels up after every chapter.
