XCOM 2

2035. Twenty years ago, aliens invaded Earth. An elite military organisation was formed to stop them: XCOM. It failed. Despite a heroic effort, the world was overrun and is now run by a joint alien-human government called ADVENT. On the surface ADVENT is peaceful and benign, pressing forward with advancements in medical technology and science. But they rule at the point of a gun and more sinister experiments are taking place in the background.

Now an underground resistance organisation, XCOM is creating sleeper cells around the world and stealing the aliens' technology to turn against them. All it needs now is a leader.

XCOM 2 is a sequel to 2012's XCOM: Enemy Unknown (and its expansion, Enemy Within), itself a remake of 1993's X-COM: UFO Defence. The X-COM/XCOM franchise has a reputation as one of the greatest video game series of all time, its combination of managing the defence of the entire planet with commanding individual combat missions against the aliens providing some truly sublime gameplay moments. XCOM 2 starts with a controversial premise: you lost the war against the aliens in the original game and now have to fight back with an underground resistance movement. There's a canonical (kind of) explanation for why you may remember winning in the original game, but you can just rationalise it as an alternate timeline if you really want.

Gameplay is similar to XCOM: Enemy Unknown, although there are a few twists. Once again you have a base of operations and have to upgrade it, building new facilities and carrying out research and development. However, your base is now a mobile SHIELD helicarrier alien cargo ship called the Avenger. You have to physically move the Avenger around the world map to recruit new agents, pick up supplies and carry out assault missions. As well as supplies (which replace money from the first game) you have to glean Intel to uncover the alien plans and you have to be more tactical in how you get hold of resources like elerium and alien alloys, which are required to research and build new equipment. When a mission starts, the game switches to a turn-based strategy map as you guide your team of up to 6 soldiers to fulfil an objective. This can vary from killing all the aliens present to rescuing a VIP to hacking a data terminal, often against a punishing time limit.

As the game continues (a first playthrough of the campaign will take around 25-30 hours) new, more powerful aliens are introduced so you have to stay on your toes, constantly researching weapons and armour so you can survive these tougher opponents and take them down. XCOM: Enemy Unknown sometimes forced you to compromise between different research tiers and trees, but XCOM 2 is positively evil in how it forces you to switch between different objectives, rush around trying to put out lots of fires simultaneously and in how long everything takes when the aliens are almost constantly attacking. XCOM 2 certainly makes you feel like you've got the whole world against you. It's a much, much tougher game than its forebear even on the equivalent difficulty levels.

It's also a game that gives you a lot of options. Character builds were something you could get away with not studying intently in the original game, but XCOM 2 is so tough that optimising your upgrade path is much more vital. For example, you can pick upgrades for your Sharpshooters that allow them to snipe enemy targets across the map with chained shots and using other soldiers to spot for them. You can also eschew that and pursue a gunslinger series of upgrades that give them up to six pistol shots a turn. A pistol doesn't do much damage, but upgrade it to a plasma pistol and fire it six times and it rapidly becomes one of the most powerful weapons in the game. The other classes get similar upgrades, with Grenadiers able to deal out masses of high damage with explosives and heavy weaponry and Specialists getting powerful drones that can dish out first aid and force fields (effectively) from right across the map. Rangers get excellent scouting and melee combat abilities that makes them formidable both at range and up-close.

For those who love rolling dice and comparing stats, XCOM2 is immensely rewarding. For those who want to just enjoy the game and get through to the end, don't be afraid to whack the difficulty down to easy ("Easy" in XCOM 2 is really not all that easy at all) and save-scum your way through the game. It doesn't take prisoners.

The game does hit the same sweet spot as the original of combining the widescreen, epic war for humanity's survival on a global level with individual combat missions, allowing you to customise your soldiers in almost any way that you please. However, whilst in-mission combat is tenser, more varied and more scenic than before - helped by the new, randomly-generated maps - the global strategic game is a lot more annoying. Some things take inexplicably long amounts of time - three days to pick up a supply drop you've just been given the coordinates to? - and you can bet that a vital, non-skippable mission will crop up 2 seconds before you'd have otherwise successfully researched your next tier of body armour. The game does a great job of making you feel like you're up against insurmountable odds, but all too often goes over that line and makes it almost impossible to proceed. The problem is that this steep increase in challenge abruptly falls off once you get the best weapons and gear and the game becomes, if not easy, than relatively straightforward.

XCOM 2 (****) is therefore a very good game, but ends up being frustrating. The combat is more interesting than in Enemy Unknown and represents a major step forward over it, but the grand strategic game feels random, arbitrary and at times tedious, and is a bit of a step back from Enemy Unknown's. Combined with the much more punishing difficulty level, this makes the game hard to recommend unambiguously. If you enjoyed the previous game and want more of the same, but more hardcore, XCOM 2 is certainly worth your time. If you haven't tried the franchise yet, I would definitely recommend starting with the previous game before tackling this one. XCOM 2 is available now on PC.

Technical Notes
XCOM 2 launched in a heavily bugged state on PC, featuring unusual lag, inexplicable CPU and GPU spikes and frame-rate drops, and occasional crashes. I was lucky in that I experienced only one actual crash in the whole game, and this guide helped improve performance immeasurably. However, waiting for a more comprehensive patch to fix the game's problems may be advisable.

XCOM: Enemy Within

Earth is under alien attack and it is up to the multinational defence organisation XCOM to defeat the invaders. But the aliens are now employing more advanced technology, including genetically-engineered creatures and mecha-suits. It falls to XCOM to adapt these weapons against the alien threat, even as it finds itself under attack by a fifth column of humans sympathetic to the alien cause.

XCOM: Enemy Within is a major expansion to the original XCOM: Enemy Unknown. It isn't a sequel to the original game, but instead completely expands and reworks it. The meat of the game remains the same: you command XCOM, researching new technologies, launching satellites to scan for alien ships and launching interceptors to shoot them down, and then deploying combat troops to fight the invaders through a turn-based battle system. The difference is that as well as fighting the aliens, you are also battling EXALT, a group of humans who have sided with the aliens. In addition to this, you can now develop G-Mods (genetic enhancements to your troops) and MECs (massive robot battle-suits) to expand the fray. Rounding things off are more advanced options to make the game harder or easier, or expand its length dramatically.

At its core, this is still the same XCOM experience as the original and if you didn't like that, Enemy Within doesn't do anything that will win you over. This is for players who enjoyed the original game and want more of it. Sadly, there aren't any new weapons (although there now more varieties of grenade) or armour, or new alien types beyond the Seeker, a flying squid-thing which can cloak and strangle soldiers without warning. The Sectoids can also now use MECs themselves, which makes this fairly nonthreatening species dangerous again at an advanced stage of the game, but still fairly easy to defeat.

A big difference is the introduction of EXALT, a sort-of anti-XCOM who use similar weapons and tactics to your own troops. They seem a bit more threatening as well, more likely to use Overwatch and their troop types includes heavy missile and sniper classes that the aliens lack. EXALT are a worthy new addition to the game, but also one that can be disposed of without too much trouble: in the course of the new 30-hour campaign I played for this review, EXALT were around for maybe 8 hours of it before I defeated them for good.

The G-Mods and MECs are interesting new additions to the game, but are of limited utility. MECs look awesome, but their weapons are frequently less capable than the ones your own troops sport and their inability to use cover means they tend to draw the fire of almost every alien on the map on every turn. This makes them, weirdly, more useful as last-minute reinforcements to use only when everyone else is committed rather than the front-line shock troops they seem designed to be. G-Mods give your troops formidable bonuses, but these tend to be more useful only on the more punishing difficulty levels.

Enemy Within does bring a huge amount of variety to the base game. There are many more map types and variety of maps, and the various optional DLC has now all been folded into the game. This results in more narrative-based Council missions and more stuff to research and build. There is also a rather nasty new surprise in the form of a punishing base invasion mission, where the aliens will actually assault your base at an inconvenient moment and you have to fend them off in one of the more tense encounters in the game.

All of that said, the basic game is still the same and some may find these new additions do complicate what was a perfectly-balanced game. Others, and such is my view, will find that the additions inject new life to a classic title and elevate it just that little more. Enemy Within (*****) is available now on console in the UK (X-Box 360, PS3) and USA (X-Box 360, PS3), and on PC via Steam.

XCOM: ENEMY WITHIN announced

Firaxis have confirmed they are working on a major expansion and overhaul to XCOM: Enemy Unknown. Entitled XCOM: Enemy Within, the game will launch on 13 November this year.

The game will be an expansion for PC users and a stand-alone boxed release for console gamers (where it will also incorporate the previously-published DLC for the original game). The bad news is that the campaign will unfold pretty much as before, with the same milestone missions such as attacking the alien base and infiltrating the enemy command ship. There's no new campaign as such. However, the existing campaign will be changed.

The most obvious changes include new weapons such as a flamethrower, which is devastating for short-range combat, and new enemies such as the Mechtoid, a Sectoid in a battle-mech suit. These battle-mech suits - known as MECs - can also be created by your forces, giving you a powerful new weapon on the battlefield. You can also genetically modify your soldiers using alien tech. Both MECs and G-mods will require a new resource called 'Melds' which need to be recovered during missions. However, the aliens will set the Meld canisters to self-destruct when you attack. This will introduce new tactical considerations to missions, with players having to choose to secure Melds, carry out their mission objectives more quickly or split their forces. Because the Melds are alien tech, it is possible for them to corrupt your soldiers if you are not careful, hence the title.

There will be 47 new maps and map-types, including much-requested farm layouts. The game will now also track how often certain maps are used and will pump in new maps to reduce repetition. The game's code has also been adjusted with some elements previously locked away in Unreal Engine files now transferred to the .ini files, allowing modders to adjust the game more thoroughly than before. However, enabling randomly-generated maps will not be possible.

This is positive news, although the lack of a new campaign or other much-requested features (like base invasions) is slightly disappointing. But anything that fleshes out the original, excellent game is certainly worthwhile.
