K240

K240 is a real-time strategy game where the player manages a franchise of asteroid mining colonies in a distant sector of space. The player begins with control of a single asteroid, a minimal colony, and one Transporter ship used to carry ore and establish new colonies. Gameplay primarily involves constructing various buildings for life support, mining, and defence.

The game takes place in a sector of space contested by one of six alien species, whose technology level and aims are similar to the player. Fog of war primarily limits the player's field of view to a small area around their own colonies, requiring the use of scout ships and spy satellites to locate and observe the enemy. The ultimate goal of the scenario is to destroy all alien asteroid colonies. To this end, both sides can construct armed space ships and deploy a variety of long-range missiles.

The year is 2380. The Terran Empire, a vast interstellar civilization spanning over a thousand worlds within three hundred light years of Earth, competes with alien species for territory and resources. Mining franchises have opened in the Fragmented Sectors, a region of space filled with asteroids.

The player conducts one such mining operation inside Sector K240, a cube of space fifty light years across. They must operate in a region of space contested by an hostile alien species, who are seeking to claim the region for themselves. Operating independently and with little official support, the player must establish mining colonies on asteroids, deploying warships and long-range missiles to drive out the aliens and claim the sector for themselves.

K240 was a successor to Utopia: The Creation of a Nation (1991), a sci-fi colony management simulator inspired by Sim City. That game was originally conceived as in the fantasy genre, but switched to futuristic in order to avoid the technical challenge of writing pathfinding code. Utopia used an isometric view in order to appear more visually impressive, and innovated over Sim City with the inclusion of a definitive enemy.

In January 1992, a sequel to Utopia was planned, tentatively scheduled for the end of 1992. Development began in May 1992, following the production of an expansion disk for the original Utopia. The lengthy initial design document was overly ambitious, and included features such as null modem multiplayer which ultimately proved infeasible. However, it defined critical new features as the ability to see the alien city directly, a greater focus on military strategy, and the asteroid-based setting.

Reviews of K240 were generally very positive. Reviewers frequently appreciated the game's engrossing and unique strategic gameplay, but some felt the graphics and sound to be lacking.

CU Amiga rated it 91%, awarding its "Screen Star" accolade, describing its random effects extending the game's longevity. The One Amiga devoted four pages to a review, which ranked it 90%, "Not since Dune 2 have we been treated to such a great strategy game". The Computer and Video Games Essential Guide ranked it 89%, describing K240 as "a masterpiece of strategic excellence" and "one of the best strategy titles ever, on any machine!"

K240 was succeeded by Fragile Allegiance (1996), a PC remake of the game with improved graphics and user interface. Many of the buildings, ships, missiles, and game concepts are the same, while the story advances to see the Terran Empire dissolved in a coup, and united with several alien races in a multiracial Federation. There are also gameplay differences resulting from ships being given limited range, as well as espionage mechanics.

The MGL data storage format used by K240 would go on to be used in Graeme Ing's 1996 PC game Normality.
