Impossible timelines

Infinity is the trilogy turning inward. Its campaign slips between failed timelines, dreamlike repetitions and the threat of something ancient being released from Lh'owon's sun. Familiar rooms return with different meanings, and the terminals ask you to assemble the story rather than simply receive it. It is deliberately disorienting—and much richer after the first two games.
