Jumping Jack

Jumping Jacks are round-specific enemies appearing in Die Rise. They look similar to the Crawlers in Call of Duty: Black Ops but come during specific waves, and can teleport in short proximity around the environment. They are downed relatively easily, but can pick off a survivor that strays off on his/her own with ease. The Jumping Jack  round essentially serves as Die Rise's Hellhound round, dropping a Max Ammo power-up at the end of the waves. If, during a Jumping Jack round, all of them are killed via Knife, Bowie Knife, Galvaknuckles or shooting them all with 100% accuaracy the last one will drop a Random Perk Bottle along with the Max Ammo.

Appearance
Jumping Jacks look very similar to the Crawler Zombies from Call of Duty: Black Ops. They are surrounded by a number of circles of electricity, and can teleport short distances on the map. They are killed in one hit with the Bowie Knife and Galvaknuckles until the third Jumping Jack round, similar to Hellhounds.

Abilities
They will explode in a flash of electricity which can hurt the player if he/she is too close to it. They will follow a player up elevator shafts by teleporting, so there is no reliable way to evade them. They will not teleport behind the player while the player is killing other Jumping Jacks, however, they will teleport directly in front of the player and begin attacking. If using the Ray Gun or Sliquifier, which do not fire normal bullets, contact does not need to be made with the Jumping Jack to receive the Random Perk Bottle.

Trivia

 * The Minions use the same models as the Crawler Zombies from Call of Duty: Black Ops, albeit bigger and with modified clothing.
 * In a livestream video, Jimmy asked a fan, Telixion about what to call the new zombies. He coined the name "Jumping Jack". The stream can be seen here, and the actuall question for the name starts at 15:39.
