Undead Guardian

"A loyal undead minion that will attack any that come within it's radius. Does not attack it's owner's ROBLOX friends."

Overview
The Undead Guardian is an NPC humanoid whom can be purchased for 250 Unobtainium Crystals. When placed in a user's base, the zombie will attack any players within a certain radius (estimated to be around half of a player's base), excluding the user's ROBLOX friends.

Bugs

 * The Undead Guardian will ignore friendship with users that you have added in a friend during the game, meaning you'll have to join a new server for your newly added friend to be safe.
 * Though the "Copy" option under the Undead Guardian's selected state reads $25k, you cannot afford no matter how much money you have. However, you can copy it for 250 uC.

Trivia

 * You can infuse your Undead Guardian by pushing it into infuser items.
 * The Guardian can be used as a test dummy, as it will take friendly fire.
 * The code "brainnssssss" could be used to obtain a free Undead Guardian, though this code is no longer valid as of the Combat Update.
 * The zombie will eat the limbs of its opponents, making retaliation against the Guardian very hard, especially as the Guardian is slightly faster than a regular player. This action will also slow the player.
 * There is also a vintage edition of this item which spawns zombies that explode on touch of a user not on your friends list.
