X-COM: Apocalypse

Similar to the first two X-COM games, Apocalypse features a map-like management mode (the Cityscape) and an isometric combat mode (the Battlescape). The management mode takes place in a single city, called Mega Primus, rather than being spread out over the entire planet Earth as in the previous games. In addition, Apocalypse was the first game in the X-COM series to include a real-time combat option as well as the traditional turn-based mode.[1]

Apocalypse features a re-done interface with new graphics. It is more complex, and the task of keeping and increasing the funding of the X-COM organization now extends to not only intercepting UFOs, but also to minimizing collateral damage, preventing alien hostile takeovers and even raiding the buildings of other organisations, of which there are several in Mega Primus.

X-COM: Apocalypse claims to have a self-learning AI-module. The game does feature self-adjusting difficulty, where player performances influences the Alien zeal to expand and infest. Sluggish X-COM responses, total failures, and a bad weekly rating slow the alien build-up of weapons and creatures (but not ships) on their homeworld. This gives the player the chance to amend their failures and rethink their strategy. For example, a high rating in first five days can make the Aliens attack the player's HQ head-on with a large heavily armed mob often. Conversely, a low rating in the first five days can make the aliens only incur twice a week, with a very small force. This also affects the equipment quality of the aliens, so if a very high score is acquired quickly (for example by using a bug that allows the player to raid allied organisations without hostile response), the very first batch of aliens might be found with personal shields and disruptor cannons (which normally would appear only much later in the game).

Half a century after the end of the second X-COM campaign, the last battle of T'leth has severely damaged Earth's biosphere. As a result, several self-contained Megalopolis-type cities were proposed to provide habitation for humanity. The game follows Mega-Primus, the first of these cities, built over the ruins of Toronto, Canada. Meanwhile, the off-world colony of Mars is exploited by the Elerium mining corporation, Solmine, and oppressed by MarSec (MARs SECurity).

The alien threat in the game is presented by a new race of organic, extradimensional aliens that initially seem to have no relation to the aliens of the previous two games, though later missions set in the aliens' home dimension reveal they have enslaved Sectoid survivors. These new aliens attack the city through tetrahedron-shaped teleport gates. The player must find out how to send their own aircraft, along with X-COM agents, through these gates without being destroyed and take the war to the aliens. Apocalypse has 14 races of alien beings including Anthropods, Brainsuckers, Hyperworms, Megaspawns, and Micronoids. Each race has various strengths and weaknesses, and some races are dependent on other races. The "alien life cycle" plays a crucial role in the game.

The player is exposed to this "alien life cycle" through research and more importantly the lower level alien attacks during specimen gathering combat. Primarily the attack of the weaponized alien the Brain-Sucker which attacks individuals after landing from a pod launcher utilized by alien foot soldiers. The Brain-Sucker hatches and attacks the nearest individual by jumping on their head and seemingly injecting something into them through the mouth and dying immediately after the attempt.

The life cycle later takes a mysterious turn as it shows no connection between the lower alien forms and higher alien forms. Eventually, however, it is found that the leaders of the invasion are the Micronoids, a race of sapient, single-celled organisms that live in the bloodstreams of the other aliens. The ultimate goal of the invasion is to inject Micronoids into the bloodstreams of important figures, allowing them to control Mega-Primus through psionic domination of their hosts. The player is eventually tasked with invading the aliens' homeworld and destroying their side of the gate to stop the Micronoid infestation.

During the creation of Apocalypse, Mythos Games created the game but MicroProse wanted to create the graphics.[2] Julian Gollop called the relationship "disastrous", and said of the game "It was a disaster area. Apocalypse was quite a sophisticated and ambitious game, but it was a big mistake from our point of view. In retrospect, we should have originally agreed to do a sequel in six months, and spent a year doing it, like they did! It would've been a lot better."[2] Gollop recollected:

After completing this game I know how Francis Coppola felt after filming Apocalypse Now. Just about everything that could go wrong did go wrong, and the amount of effort required to pull it into shape was immense. After three years of hard work and five different producers X-Com: Apocalypse finally hit the streets. The initial game design was definitely too ambitious and too complex. The aim was to recreate in some detail the events, organisations and personalities within a futuristic megalopolis. Each corporation had a leader who could be tailed, arrested, interrogated or assassinated. Organisations could buy and sell buildings as their financial fortunes changed. X-Com agents could spy on other organisations to gain valuable information. A sophisticated diplomacy display allowed the player to instigate aggressive or defensive alliances with other organisations. There were multiple alien dimensions, generated pseudo-randomly, and the aliens gradually expanded their empire as the game progressed. The game also featured a scenario generator and multiplayer options using a hotseat turn based system or a real time LAN option. Most of these features were implemented to some degree, but were finally stripped out due to the horrendous amount of work involved in QA and debugging.[3]

On XCOM: Apocalypse the team size for that actually was 5 of us at Mythos Games working on it and there was a team of artists at MicroProse working on it as well. Again, it’s a similar arrangement to the first game where we were doing the programming and MicroProse were doing the artwork. ... the MicroProse art team were trying to change the design of the game. Then they were failing to actually deliver anything that they promised. They just couldn’t get the isometric graphic system sorted out in their heads. They did things which just didn’t work, like they hired a guy whose name I forget to design the aliens, and this is a well known science fiction artist and he built these big models of the aliens and the idea was that they were going to scan them and put them into a 3D modelling software. It just didn’t work. He had all this fine detail in these models and this scanning system just wasn’t good enough. Then they had to recreate them basically in a 3D software they were using at the time. Yeah, they were awful, blobby things. They were nasty. Terrible graphics. It was very difficult.[4]

Artist Terry Greer recalled: "My main memory of Apocalypse was the pain we all went through. It was a hugely ambitious project and used a mix of rendered and hand drawn artwork from a variety of graphic styles (which didn't always work - although all the individual bits were great). Probably the worst fit was Tim White (an established SF artist) who had been commissioned to do the character designs. I like Tim's work, but his models were intensely detailed and quite unsuitable for reducing to the scale needed for an isometric game of this type. The creatures he designed looked great full screen, but reduced to the size they would be ingame they were often unrecognizable blobs. I don't know the reasons behind the decision to hire him, only that the problems were apparent to everyone in the art department, and I would have loved to have seen them ditched."[5]

X-COM: Apocalypse was originally released on June 30, 1997. It was re-released as part of the compilations X-COM Collection by Hasbro Interactive in 1999, and X-COM: Complete Pack in 2008 and 2K Huge Games Pack in 2009 by 2K Games. On September 5, 2008, the X-COM series, including X-COM Apocalypse, became available for sale on Valve's Steam platform; the game runs in a specially configured version of DOSBox.

In 2014 a group of developers formed to remake the game from scratch in C++, under the OpenApoc title. By 2018 the remake had reached an Alpha release state with the entire game playable from start to end and a growing community of developers and players.[18]
