XCOM: Enemy Unknown - seven essential tips you'll need to save the Earth

8th Oct 2012 | 13:25

As you'll know if you've read our XCOM: Enemy Unknown review, the latest Xbox 360 release from Firaxis makes being hard an art. It's a game about juggling resources, struggling to get by, being forced to make life-or-death decisions.

We'd highly recommend playing on the Classic difficulty setting - Normal is a little too forgiving - but you might want to pick up a few pointers first. The early stages of the invasion won't pull any punches. Start reading ahead if you want to survive.

1. MAKE A B-TEAM

Rookies aren't much use in the field, and have a habit of dying. Soldiers are cheap enough to replace, but don't get into the habit of shrugging death off - success in the later stages of XCOM is dependent on the quality of your troops, which means keeping them alive for long enough to earn those promotions.

Taking a full squad of rookies into the field is suicide, but it's worth bringing someone fresh along with you on every mission. Aside from the Assault's invaluable Run & Gun skill, most of the classes take a while to get good. Snipers are rubbish for the first few ranks, but eventually develop utterly invaluable skills. Read our XCOM: Enemy Unknown class guide for more pointers.

Rely too heavily on your XCOM A-Team, and you'll soon find yourself in a sticky situation. If a Terror Mission pops up while the heroes of your squad are still in the infirmary, prepare to sacrifice a couple of rookies at least. The officer training facility can be handy: it lets you buy upgrades that increase your squad size to six, which makes spreading out the promotions much easier.

2. DON'T KILL EVERYTHING

You won't have been playing XCOM for long before the research team starts bugging you to make an Arc Thrower. Get close enough to an alien whose health is low, and you'll be able to zap the cheeky git unconscious and haul it back to base. Interrogating a species unlocks research credits, speeding up the rate at which you unlock certain specific technologies.

Because of this you'll want to capture aliens as soon as possible, but doing so always puts you at risk. It's best to give your Arc Thrower to a Support class soldier - the extended movement range perk makes things much easier, as does the upgrade which adds a secondary inventory slot. If you can't quite make it to your foe in one movement, find some good cover and use the Hunker Down skill. This ability gives you full protection against critical hits, which should help you survive any last-ditch resistance.

Get into the practice of capturing live foes, and you won't have to invest as much money on your research team, allowing you to spend cash on engineering.

3. INVEST IN ENGINEERING

It's easy to get carried away with building research labs, but it's worth making a few workshops as early as you can. Placing them adjacent to each other in your base gives you a 7% spending rebate per workshop. In addition, the engineers that come with it will reduce the cost of making new stuff.

Later in the game you'll find the costs of building weapons and armour a little more hefty than you might expect. Invest in engineering early and you'll save a fortune in the long run.

You'll also be quids-in when it comes to meeting requests for equipment. If some chaps from Russia want to buy some laser rifles, get down to engineering and build them immediately. Using up rare materials in the process might not be wise if you're running low, but when stockpiles are at bursting point, this is a bit of a no-brainer.



4. DON'T MAKE CLONES

Having a back-up squad is important, but don't automatically choose the same set of skills. Most class promotions let you choose between two skills, and it's a good idea to take advantage of the options. Abilities like the Sniper's Squad Sight are far too effective not to be a staple, but many of the other choices aren't black and white.

Different types of mission require different tactics, so don't be afraid to adapt accordingly. The Ghost armour is mainly useful for getting a Sniper into position, but also proves invaluable for a Support on terror missions - allowing you to quickly run around the level saving civilians without being seen. In the later stages of the game you'll also get a heads-up about the enemies you're likely to face in each mission, giving you no excuse not to be prepared.

5. SELL THE JUNK

Trading dead bodies for cash on the Gray Market is a good way to make extra cash for emergency purchases, but don't forget to keep an eye on the bottom of the list: partially destroyed UFO components have no research or engineering benefit, which means that they can be sold without a second thought.

The junk's only worth 50% of its true value, however. Selling fully-working UFO tech is a fantastic way to make huge amounts of money - just be sure that you keep a few for the sake of research. If you're confident in the abilities of your ground team we'd recommend engineering an EMP cannon, which will allow you to shoot down UFOs without causing the craft any serious damage. You'll have to fight more foes on the ground, but the rewards are worth it.

6. DO YOUR JOB

Once a country pulls the funding from the XCOM project, there's no way of getting them back. They aren't as exciting as brand new weapons, but don't forget to invest in building satellites. Whacking one in the skies above a country will reduce the panic in the area, as well as boosting your monthly income. When choosing between alien abduction missions, always go to the location where things look the worst: improved morale from successful mission completion will be wasted on regions that are already quite chilled-out.

Don't let that "Very Difficult" rating put you off - if too many countries stop funding XCOM the game will end. If things are looking really dire it's worth pushing ahead to the next story mission: beating these will usually lower panic levels across the world.

7. ONLY BUY WHAT YOU NEED

Don't bother manufacturing 18 separate suits of armour. You can swap gear between troops, and gear isn't destroyed when the wearer dies. Swapping equipment around can be a bit of a fiddle, but it's worth doing if you're trying to save money. Giving new recruits better guns will help them level up faster, but it's always best to save the expensive armour for the most qualified members of your team.

Most soldiers only have one inventory slot, so you'll want to make sure that it's being properly used. Grenades are great in the early stages of the game, but after that you'll want to buy almost everyone a S.C.O.P.E. The boost to accuracy you'll receive from one of these is a massive benefit to almost everyone, and ensures that rookies aren't useless in the field.
