Science fiction games explore futures shaped by advanced technology, space travel, and speculative ideas. From the bullet-strewn co-op of Helldivers 2 to the mind-bending puzzles of Portal and the irradiated wastelands of Fallout 4, the genre asks what happens when humanity, machines, and the unknown collide. Expect alien worlds, experimental weaponry, and stories that probe big questions about progress, identity, and where our species might be headed.
