K240 is a space strategy game developed by Celestial Software and published exclusively for the Amiga by Gremlin Graphics in 1994.
The game was designed by Graeme Ing, the author of Utopia: The Creation of a Nation, of which K240 can be considered a sequel. In this space city-building game, you start colonizing an asteroid field in sector K240, mining valuable ores, building power generators, and other facilities. You will have to manage the colonies, solving all the problems that might arise, including upset workers. But most importantly you will have to defend the colonies from other alien species, building fighters, rockets, and space stations. Building strong defenses will be necessary and sometimes it won't be enough, you will have to attack to destroy the enemy bases.
Compared to Utopia, the graphics were not improved much, but K240 offers many more management options, plus the military aspect is entirely new. This makes the game richer and rewarding to play.
The game received very positive reviews and it still has a lot of fans. It was never officially ported for PC, but in 1997 Gremlin published a game named Fragile Allegiance that is essentially a remake.
