While being indecisive about what game I should make a blog about, I noticed that all three had scoped rifles in the game. So that's when I decided to make my blog about how well the three games implement bullet ballistics.
So I present to you...
G.O. Call of Elite Sni-per 3!!!!
A mash of both Call of duty, Counter Strike: Global Offensive, and Sniper Elite 3.
First let us start with Sniper Elite 3. Sniper Elite 3 is a game set in June 1942, where during the Battle of Gazala, OSS sniper Karl Fairburne is sent to assassinate General Franz Vahlen and uncover his top-secret project. To me this game is very addicting, mostly due to its grueling yet astounding bullet-time camera. This happens in the game when you fire from a long distance and hit the target in an interesting spot, such as the head, or as most players try to aim for, the testicles. Observe this Footage:
The Bullet shown was shot from a Mosin-Nagant. This rifle has on average an 800m/s bullet. From the range of 657 meters,assuming no air resistance, we can use the equation X= Vot + 1/2at2 to calculate that the bullet traveled the 657 meters in the X-plane in .82 seconds. From this we can find that the bullet dropped 3.308 meters in the y-plane. However, this is calculated with out drag forces, so to find the bullet drop with air resistance, we need to find the drag coefficient, which through the use of the handy-dandy electronic web of information, we learn we must use the Ballistic coefficient Equation: BC=M/(Cd*A). Where BC is ballistic coefficient, M is the mass, and A is cross-sectional area. The Cross-sectional area of a bullet that can be fired from a Mosin-Nagant, the 7.62*52mm, would be .121 m2, with a mass of .012kg. For this bullet, the Ballistic coefficient would be 1.055 units for 657 meters. Using all this information, we calculate the drag coefficient to be .00137 units. From this, we can calculate the force of air resistance to be 1.1 Newtons using Fdrag=CV2. This allows us to find the new time it takes for the bullet to travel through the air, which is 1.09 seconds, which also allows us to find our new displacement in our y-plane, which is now to be 5.843 meters, very different than our calculation without Retarding Forces.
Now let us look at the bullet Physics in Call of Duty: Modern Warfare 2. If you have played this game, you will know that this sentence makes no sense because there is no bullet drop. HECK, there is no ballistics in this game. The bullets travel out of your gun and travel in a straight line. Because of this flaw in the game, people have created a move called a 360o No-Scope. You spin your character around in a complete circle and blindly fire, hoping that through the shear improbability of it happening, which most of the time, travels through reality, just to kill some one as shown here.
However, If you wanted to learn about the physics of the 360o No-scope, you can turn to this video of someone accurately describing the physics behind the infamous 360o No-scope in a game called Counter Strike: Global Offensive.
Thank you very much for reading, and as always, watch out for impossible reality phasing projectiles.
