Sci-fi is one of the biggest, most distinctive genres in cinema and literature. It's arguably an even bigger deal in gaming.
Whether you're taking direct control of a space marine blasting alien invaders, flying a starfighter, commanding a space station, or negotiating a dystopian state, some of the most compelling games take place in a sci-fi setting.
That's true of mobile games as well as console and PC. From ports to iOS originals, the future is a fertile place for games you can play on the go.
It's been tricky narrowing the field down to just 25, but the following games all create an evocative science fiction world that goes beyond flashy lights and big explosions. Mostly, anyway. There's still plenty of space for such frivolous things.
Which sci-fi iOS games would you add to the list? Let us know in the comments below.
