Katana

Description
The sharp sword with very high damage and pretty fast attack speed, making it the best melee weapon in Left 4 Survival. The Katana can easily kill any zombies especially zombies with high health like Banshee and Shaman. However it cannot cut the Tangler's tongue, unlike the Machete which could. It can be bought for 350 Robux.

Survivors

 * Prepare to use this to conserve your primary's and even secondary's ammo, due to its high damage.
 * This can be useful against high health zombies, as it can kill these zombies quickly, especially Banshee.
 * If a Banshee is attacking you, prepare use the Katana to kill the Banshee rather quickly, it can help you conserve any ammo.
 * Keep in mind that the Katana cannot cut the Tangler's tongue to help you free yourself as compared to Machete, so be aware.
 * Just one Tangler can kill you, so it’s best to kill Tanglers first if you don’t have a teammate as well as Defenders.
 * Katana does not have any abilities, so be wisely using this.
 * Avoid fighting the Bloater with this, as it will explode when killed, it can easily drain your health making you worse than you should be.
 * You can counter this by switching to a Primary or Secondary or run away from the Bloater.
 * If you planning using this against a Juggernaut, wait until it’s on low health, then swing the Katana to it to kill it.

Zombies

 * It's best to not attack a Katana user as a Banshee, as they can kill you quickly.
 * The Katana cannot cut the Tangler's tongue as compared to Machete so you don't have to be worried about catching them with your tongue as the Tangler.
 * Be smart catching the Katana user as the Hunter, as the Katana can kill you instantly.
 * Katana can kill high health zombies with a few swings, so if your spawn one of these high health zombies, try to attack the Katana user smartly.
 * As a Bloater, try to get too close to a survivor with the Katana, due to its short range just like the melees, as you can get exploded upon death, it will remove most of the Katana user's health.
 * This can be countered by running away from you or quickly switching into a Primary or a Secondary.
 * Normal Zombie will be a bad idea to use, as its lack of abilities and low health can get it punished by a Katana very quickly.
 * When countered a Katana as a Inferno, you should combust quickly as the Katana can deal massive damage which kills you pretty fast if not quick.
