The Alternity game is TSR's roleplaying game of modern action to far-future adventure. It's science fiction, in so much that it draws upon the speculative storytelling style that deals with the future, space and scientific breakthroughs yet to be made. It's a game of "what ifs."
What if... humanity develops a means to travel among the stars? What if... We aren't alone in the universe? What if... the world we know ends tomorrow? What if... alien entities invade our world?
No matter what supposition or speculative leap of imaginiation you come up with, as long as it is founded in a scientific (or quasiscientific) theory that's internally consistent, you're in the realm of science fiction. From a modern world that looks like today but features a technological twist that makes it a very different place (like a new weapon, computer or other device), to a far-future era where humanity has moved to other worlds, any setting and any technology is easily adapted for play.
