So, I finished the game in just over a week. Partly that's
because it's of moderate length, and partly it's because I played it a lot.
Story
Aliens have invaded and are killing people, the
extra-terrestrial scum. You are the commander of XCOM, which is basically an
elite global army. Supported by a German scientist, a Chinese engineer, an
American military adviser and soldiers from around the world (who all have
American accents) you must defend Earth, defeat the aliens and try and keep all
your financially supportive nations onboard.
Gameplay
The game has a strategic aspect, which takes part in the
XCOM base, and a tactical aspect, which happens on the various battlefields.
The base has lots of scope of development. It's
subterranean, but slightly less than a quarter of it has actually been
excavated and built upon at the start of a game. Adjacent facilities of
identical/similar function (power generation, for example) confer bonuses, so
if you plan ahead you get essentially free stuff. However, the costs of
excavation increase as you dig further down.
Just about every sort of facility is useful in one way or
another, making it tricky to decide what to build, and as space is strictly
limited (as are funds) these decisions will drastically affect your style of
play.
The player also has to decide what to research, build and
improve using the labs, workshops and foundry. This will affect how well
equipped your soldiers and fighters are, and could make the difference between
success and failure. Losing battles and having your planes/satellites shot down
will only increase panic and could prompt your financial backers to pull out of
the XCOM project.
There's a real sense of crisis management, as you'll often
be presented with difficult choices. Keeping all the nations together can be
hard when you're offered a choice of three countries, each verging on terminal
levels of panic, to rescue from alien incursion. Even on normal difficulty this
isn't straightforward.
The tactical battles are usually challenging and almost
always great fun. After graduating from rookie status soldiers are randomly
assigned one of four classes. Heavies have machine guns and rocket launchers,
and support units are ideal (once they get some promotions and corresponding
perks) for healing your soldiers. Assault units are frontline fighters and the
sniper, perhaps my favourite class, can wreak carnage over long distances.
Each class has a secondary weapon (pistol for all save the
heavies, who get a rocket launcher) and can be outfitted with an optional
fourth accessory-type item, a main weapon and armour. This, coupled with the
variable perks picked upon promotion, mean that units of the same class can
vary somewhat.
Sound
The music of the game does a perfectly decent job without
being especially outstanding. However, as its job is strictly to provide a
backdrop that's not too bad.
Voice acting is generally good. The three individuals
(scientist, engineer and military) you see back at base are pretty well-voiced,
and the soldiers likewise. However, some more variable accents for the soldiers
would have been welcome.
Sounds effects are good, and some are excellent. I love the
sizzle of lasers as they cook aliens, and even the bog-standard assault rifles
have a nice thumping bass as they rattle off bullets.
Graphics
There could be a little more variety in battlefields, such
as having desert, semi-arid, mountainous or snowy places to play Kill The Alien
in. However, there's a decent mix, and they're all graphically sound. The
graphics of characters, weapons, armour and so on is solid or good,
particularly given that most of the time on the battlefield you're presented
with an isometric view rather than close-ups. When you do get a close-up (when
a soldier kills or dies) then the graphics are sharp enough without being
spectacular.
Sometimes there are issues with loading in textures,
particularly noticeable for the Skyranger (transport plane) and the distant
background as the Skyranger lands.
Bugs and Other Issues
In addition to the sometimes slow or absent texture loading,
the game could run more smoothly. Especially on battlefields with many aliens
the picture sometimes became jerky and delayed.
It's also the case that the game (out of a single
playthrough) froze on me perhaps half a dozen times. Certainly not
game-breaking, but definitely a pain in the arse.
SHIVs seem slightly bugged. Most of the time they work fine,
but if you put one in your squad for a mission and it doesn't show up, don't
take it along. This happened to me once and on the battlefield it was a
motionless humanoid shape. The game then froze. If the SHIV (or SHIVs) appear
as normal they should work fine.
Longevity and replayability
A playthrough will only take something like 20 hours (it
varies a bit because you can delay doing priority tasks). However, there is a
constant feeling of progress during this time.
Replayability is very high, because the battlefields, even
for key tactical missions, are randomised. So, no two battles are the same, and
the difficulty is hard enough to be challenging but not so hard it's
frustrating.
Conclusion
XCOM is a great game which offers good gameplay at the base
and on missions, a strong challenge and the possibility of defeat (something
often absent from modern games). It does have some bugs but these are
relatively small and don't seriously detract from an addictive, entertaining
and very well-designed game.
I don't usually give scores, but XCOM: Enemy Unknown would
get 9/10 from me.
