Are you new to the game, and have no idea what gun you should buy? Well then YOU'RE A NOOB! But it's this wiki's job to make you not a noob. Here is a brief introduction to Machine Guns.
What are Machine Guns?
Machine Guns are a category of guns purchasable from the shop.
Machine guns are often fast-firing, and carry very large clip sizes. However, there usually isn't a large clip size to reserve ammo ratio, so there isn't a lot of reserve ammo to support the clip. In addition, reloading for machine guns often takes up a LOT of time, making it unwieldy if you're facing a constant stream of zombies.
They do not seem to have a lot of power behind each bullet- some take over 10 bullets for A SINGLE KILL. Nor are they very accurate. There is a famous tale of a machine gun user that shot toward one zombie, and killed one behind him (10/10 lore points).
Also, machine guns give you a large walkspeed decrease. And all of them are pretty costly.
On the bright side, compared to how many bullets they churn out per second, machine guns do not have a lot of recoil. They're relatively easy to aim.
How do I use these?
Machine guns, however unwieldy, boast a large firing rate, large clip sizes, and low recoil. They're best used at medium range, away from the prying arms of zombies so you can run, but close enough that bad accuracy isn't a huge problem. It also gives you enough time to reload before the zombies get you.
Many players who use a machine gun fire away at hordes of zombies, so that they get a hit no matter how bad their accuracy is.
