Gersh Device

The Gersch Device (also referred to as the Black Hole Bomb) is a new weapon that appears in the zombie map Ascension. One of the Ascension achievements involves killing 5 zombies with one Gersch Device. After being completed, the player will complete the acievement, "35G- They're going THROUGH!". It fills up the player's Tactical grenade slot. It is one of two Tactical Grenades in Ascension, the other being the Matryoshka Dolls. It creates a small singularity event sucking any nearby zombies in, awarding the player 50 points per zombie. A player can dive or jump (but not walk or sprint) into the black hole which will teleport them to a random location.

Trivia

 * It is also known as "Project Mercury" according to one of the Ascension radio's.
 * It will start pulling every single zombie on the map, but since it only lasts 10 seconds, it will release them before pulling them in. The closer they are to the device the stronger the pull.
 * If the device is thrown out of the map, it will not activate and Samantha Maxis will laugh at the player.
 * Players aren't affected by the black hole's gravitational pull, though players can be teleported to seemingly random locations by jumping or diving into it.
 * The Gersch Device requires some adjustment time before it can be thrown but slightly less than the Monkey Bomb making it more useful in a pinch.
 * If you have a Ballistic knife in your hands while a Gersch Device you thrown is active, you will receive 130 points for each zombie that goes in the hole, instead of the usual 50 points.
 * The achievement relating to the Gersch device misspells it as the "Gersh" Device.
 * Usually the place the player is teleported to is somewhere near one of the Lunar Landers.
 * Space Monkeys will run and jump into the black hole willingly. However, this only teleports them and does not kill them.
 * The Gersch Device was the nickname given to "Project Mercury" by the scientist that was working on it at the time. Gersch was in charge of this scientist, Yuri Kravcheski, who was Gersh's assistant and evidently admired his superior, but as evidenced by the Ascension Radios, only for a certain time. When Gersch took Yuri off the project to work on rockets, Yuri was driven insane by Samantha Maxis.
 * If the player throws a Gersch Device at the ground whilst being in a complex that has multiple levels, the player will be teleported one story down, therefore it is an easy way to escape zombies.
 * The Gersch device is at the center of an easter egg to repair the Kassimir Mechanism.
 * According to the radios, the Gersch Device wasn't originally meant to be used as a "black hole bomb", but as a portable teleporter.
 * It is possible to throw the device without priming it; throw a frag grenade, then as soon as it is thrown, throw the device. If done correctly, the player would have instantly thrown the device straight after throwing the frag grenade.
 * Sometimes if you throw one a zombie will keep acting like it is being sucked into it even if it is done.
