I have gotten sidetracked this week by the new video game The
Last of Us, which was released last week. I had not planned to buy it, but
with its glowing reviews (some have compared its potential effect on video games
to what Citizen Kane did for movies) and the fact that much of it takes
place in my ancestral home of Pittsburgh, I broke down and bought it. I’m not
all the way through the game yet, but I have to agree with the glowing reviews.

Visible here are the US Steel Tower, BNY Mellon Center, One Oxford Centre, and the Fort Duquesne Bridge. Also making an appearance in the game is Fifth Avenue Place and the underpass of either the Liberty Avenue Bridge or the Boulevard of the Allies. While these features are not necessarily in their proper locations or proportions, the designers obviously did a lot of research into downtown Pittsburgh. |
That said, The Last of Us is not for everyone. The
game takes place in a post-apocalyptic United States. In that respect, it is
similar to the popular Fallout series, in which you run around the
mostly depopulated, anarchic, post-nuclear wasteland of the US, crawling inside
ruins of famous monuments, avoiding mutants, bandits, and high-radiation areas,
and generally just trying to survive. While I like the Fallout series
and find it to be an interesting game, it is very depressing. And I do not
understand why many fans of its publisher Bethesda were excited when Bethesda
cut off further development of downloadable content for its hugely successful Skyrim
title (with its story still unfinished) because they thought it was putting
resources into the next Fallout game.
But The Last of Us makes the depressing Fallout
look like Disney World by comparison. While Fallout tempers its grim story with
an acknowledgment that it could never happen, largely because before the
nuclear war the United States as depicted in Fallout was some weird
1950’s-style creature with futuristic technology – in short, a country that
never existed – The Last of Us goes out of its way to explain that what
was destroyed was the United States as you know it now, as well as at least 60%
of the world population.
The apocalypse that forms the basis of The Last of Us’
world is not a nuclear war, but an almost overnight biological pandemic. A
mutated strain of the fungus Ophiocordyceps unilateralis (“cordyceps”)
infected much of the population, turning them into zombie-like creatures. In
that respect The Last of Us is like the Resident Evil series and
other survival horror games (though regrettably Resident Evil seems to
have abandoned that genre as of late). The zombie apocalypse has always been a
mainstay for horror. It can be far more frightening than nuclear attack
inasmuch as while a nuclear attack is devastating to life and property, once it
destroys, kills, poisons, and irradiates, that’s it. There are devastating
after effects, but once it happens, it’s done and steps can be taken to start
some sort of recovery. By contrast, the zombie apocalypse is ongoing. What it
does not kill it turns into more zombies. Their presence puts anyone at risk of
becoming a zombie and makes large areas uninhabitable. You can’t start recovery
because you can’t stop the zombie outbreak.
Which is exactly what happens in The Last of Us. The
cordyceps is initially spread through spores. You inhale the spores and the
fungus starts growing inside your body and gradually taking over and destroying
higher brain functions. Removal of the cordyceps without killing the host is
impossible. In the case of the most hated enemies in the game, the “Clickers,”
the fungus has taken over them entirely. The cordyceps has taken over their
bodies entirely, warping them physically, growing over the top of their heads
and through their eye sockets, destroying their eyesight. They can only see by
“clicking” for echolocation. Their humanity destroyed, the Clickers only goal
is to spread the cordyceps fungus, this time by biting.
The very limited backstory to The Last of Us
indicates the cordyceps outbreak spread almost overnight. With removal of the
fungus impossible and all attempt at vaccination ineffective, the US government
tried to set up “quarantine zones” around major cities where the uninfected
could live relatively safely behind walls and barricades. But as the uninfected
population continued to fall and as many of the remaining uninfected were
wracked by despair and privation, many of the quarantine zones were abandoned
or fell to bandits, civil war, and the cordyceps itself. The government of the
United States still exists in The Last of Us, but it controls only a few
cities of the continental United States, under a state of emergency, its
security forces hypervigilant and at times corrupt.
It’s a horrifying picture, a horrifying story, made much
more uncomfortable by the fact that the Ophiocordyceps unilateralis
fungus is an actual real-life infectious fungus.
So, can The Last of Us actually happen?
It probably helps and is very comforting to know that while
the Ophiocordyceps unilateralis fungus is an actual real-life infectious
fungus, it only affects ants, grasshoppers, spiders, and other insects and
arachnids. In fact, it’s considered a good thing to help control these populations.
Given the differences in physiology and biochemistry between insects and
humans, the possibility of cordyceps spreading to humans is minimal.
Even if it did spread, the possibility that the cordyceps
would spread the way it does in The Last of Us and affect human behavior
is almost zero. While the cordyceps has been known to wipe out entire colonies
of ants, it is not known to turn infected ants into attacking mutants. What it
does do is, as the fungus grows within and on the ant, it turns the ant into a
zombie who climbs to an overhanging leaf and clamp down on a major vein with
its mandibles. Then the ant dies and the fungus turns the corpse into a
fruiting body to spread the spores. What it certainly does not do until the
ant’s death is destroy physical abilities of the ant, such as its eyesight,
which would seem to actually inhibit the spread of the fungus. Obviously and
quite understandably, Naughty Dog, the developers of The Last of Us,
took some liberties for purposes of putting together a gripping story.
The portrayal of the collapse of civilization in The Last
of Us is chilling but history strongly suggests a major pandemic would play
out much differently. If one examines what is believed to be the worst pandemic
in human history, the Black Death, which killed an estimated 75 million – 200
million people across the Eastern Hemisphere in the 14th century,
one can find few similarities with The Last of Us. The Black Death
(still not fully explained but often believed to be a form of bubonic,
pneumonic, and septicimic plague spread by the rat-spread Yersinia pestis
bacterium) wiped out an estimated 30-60% of Europe’s population, including
entire towns. It caused major socio-economic upheaval across Europe (check out
Giovanni Boccaccio’s Decameron, for instance), but government (albeit
government a lot more limited than it is today) never ceased
functioning, never retreated into walled, barricaded cities, never abandoned
large portions of the territory it ruled to the plague. And that was when the
cause and spread of the Black Death was entirely unknown and government’s
response to it almost totally ineffective.
The US government’s response to disasters is not always
stellar (see, eg, Hurricanes Katrina and Sandy), but it is far, far better than
is the norm across the globe, and it is far, far better than is portrayed in The
Last of Us, in which the government response is actually worse than the
response to the Black Death more than six centuries ago. Tools for fighting the
cordyceps infection, such as gas masks, ingress screenings and bleach (to kill
the fungus itself), are shown in The Last of Us and would in real life
form the basis of a much more effective response than the one seen in the video
game.
So,
The Last of Us is a great game, a great story,
and a great chance to ask “What if?” And it should be enjoyed (if one can
“enjoy” such a depressing scenario) as such. But the actual possibility of
The
Last of Us happening is next to zero.
