X-Bow

According to Wikipedia, the crossbow is a type of weapon based on the bow, consisting of a horizontal bow-like assembly mounted on a stock, which shoots projectiles called 'bolts' or 'quarrels'.  The crossbow, as it's come to be known, has played a significant role throughout history, especially in the greater European and Asian continent, as well as the Mediterranean region.

The traditional bow and arrow has been a common tool since the dawn of recorded history, which required considerable strength and skill to master.  Comparatively, the crossbow possessed much of the same accuracy, but required much less training and expertise.  In ancient and medieval times, the bowmen were considered to be of a separate and superior caste, while just about anyone could be drafted to use the crossbow.

In the modern day, the crossbow, like it's cousin, has transformed and evolved many times, still as common and popular as ever.  Today, it is used primarily in sport and hunting, and with the popularity of The Walking Dead's Daryl Dixon, played by Norman Reedus, a whole new interest in the crossbow has been sparked.

The crossbow has always proven it's worth throughout the annals of time and I'm certain it will continue to do so, long into the future, whether there's a zombie apocalypse or not.  Where it seems to be a useless weapon, in my humble opinion, is sometime long long ago, in a galaxy far far away from our own.

In the Star Wars universe, Wookiees were a civilization advanced enough to have developed modern tank-like weapons and the ability for space travel, yet many of their hand-to-hand combat weapons in their arsenal, were still of a primitive-based design.  Bow staffs and spears were used in addition to laser blasters and cannons.  The crossbow is also a popular weapon used by the Wookiee armies.  It seems peculiar, to me, that the Wookiees had the foresight to develop stronger more destructive weapons, but still avoided casting aside their more inadequate weapons.  Though I never looked real close during the war on the Wookiee planet in Episode III, Revenge of the Sith, I'm sure there were still some Wookiee soldiers using rocks and stones.

The most prominent Wookiee of them all, Chewbacca, eventually left his home planet for a life of adventure, skipping around the galaxy with his companion, Han Solo, and though there were many instances that occurred in the time in between, the Wookiee never cast aside the main weapon of his people, the crossbow.

An impressive weapon to look at, intimidating in some instances, overall the weapon is bulky and inadequate.  For one, the crossbow (as it was used on the planet Earth) was designed for the ease of shooting ballistic projectiles like bolts and/or arrows.  In all of the times that I've bore witness to the use of the crossbow by Chewbacca, never once have I seen a quiver or any ballistics of any sort, being flung out by his trusty crossbow.  Hell! If you look closely at Chewies Bowcaster (pictured right), you'll notice that there's nowhere for a projectile, of any sort, to be launched from this outdated weapon.  

Filmmakers are in such a rush to design unique looking weapons for their sci-fi movies, that they set aside practicality for whatever looks cool and dangerous.  As stated before, Chewbacca's crossbow, looks impressive and even intimidating, to some degree, but it's better served as a museum piece.  An artifact worthy of spectacle and storytelling, rather than heated combat.  An outdated relic of ancient weaponry has no place in the  future, a long long time ago.
