Astronaut Zombie

Astronaut Zombies (also known as Cosmonauts by Nikolai Belinski) are a type of zombie that only appear on the Zombies map Moon.

Overview
Astronaut Zombies violently explode upon death, sending the player flying many meters back, even in normal gravity. If there are any zombies in its close proximity when it is killed, they will die. Zombies killed by an explosion from an Astronaut Zombie will count as kills and award 50 points per zombie killed to whomever killed the Astronaut, unlike with Crawler Zombies. The explosion caused by an Astronaut Zombie's death has a 10-meter radius, powerful enough to send players flying in low gravity areas.

Astronaut Zombies always have a red player name above them. The name above them is always one of the host's friends or someone who recently played with the host, except when playing solo, in which case it chooses from a list of predetermined names.

It will immediately spawn after the first teleportation to the starting room on the Moon, or round two. After every death it suffers, it will spawn again with a different name above its head.

Behavior
Astronaut Zombies grab and head-butt any player that gets too close, causing them to teleport to a random point on the map. In addition to this, it will take a random perk (though typically the first one received), re-arrange the order of the perks the player still has, and critically damage the player's health. If a player is unfortunate or unaware enough to be grabbed by this Astronaut Zombie, they can escape by pulling back on the analog stick quickly (within the first few moments of being grabbed), and jumping just before the Astronaut would normally head-butt them. For about a second or two after being freed from its clutches, the Astronaut Zombie will behave like a typical zombie and will swipe at the player, causing normal damage typical of average zombies.

Astronaut Zombies do not react when shot, and they move very slowly, similar to a Napalm Zombie. Their health is the same as a Napalm Zombie, which is four times the regular health for a zombie on a given round, times the number of players (e.g. on round 2 with 3 players, the Astronaut Zombie has: 250 * 4 * 3 = 3,000 health), making it extremely hard to kill through conventional guns, although if an Astronaut Zombie is not killed, his health will be the same as the round he spawned in. Similar to the Hellhounds, Astronaut Zombies are not affected by multipliers. As such, the best weapons to kill them are shotguns, the Python, and most explosives. If a Q.E.D. is thrown at it and explodes in the same fashion the Astronaut would upon death, it will result in an instant kill if the Astronaut Zombie is caught in the center of the blast radius. Shooting or damaging the Astronaut will not get the player points, however, the player will earn 50 points upon killing it.
