Back in the days of the Commodore Amiga, I used to enjoy a game called UFO Enemy Unknown.
Alien races swarm to Earth and abduct people, build bases, and terrorise cities. It is your job to defend the Earth by scouting for alien ships, researching alien technology and eventually going to the source of the alien invasion and battling the Mother Brain.
It will provide endless hours of fun, and will have you flailing your arms as your men give in to alien mind control games.
You’ll most likely need DOSBOX to run this game, unless you have an old 486DX laying about.
