"EM acceleration from this gun can send a projectile through just about any target including walls. Highly experimental, highly powerful. "
The HIKS 888 CAW is a fully-automatic Energy Sniper rifle in SAS: Zombie Assault 4 released by Ninja Kiwi as of the Easter Update. It is based on the JKH 0.887 CAW from SAS: Zombie Assault 3. It costs 400 NK coins, making it the most expensive weapon in the game, along with the Torment, Zerfallen, and the CM 000 Kelvin. Athough the rate of fire is relatively slow, when shot, it leaves a trail of what appears to be a light blue laser streak that goes through everything for about a couple of seconds before the streak disappears. This weapon is very useful when it comes to shooting down bloater spams during VS events, as this gun can take all of them down at once, and furthermore, you have a great chance of taking the majority of them down even if you hit a wall. This also comes in handy when taking down zombies inside the pods in Zombie Pods. Unfortunately, this gun doesn't have the ability to destroy destructible walls and objects since it goes straight through them; thus only being able to hit zombies. This also means that cash registers will be unaffected, as well as the doors in Survivors. Overall, however, this gun seems to be pretty useful in taking down huge spawns that are relatively close together, since you have to remember the fact that this gun is based on aim, not rushing. Also, this gun could come in handy for a person who can use the shoot-beyond-wall feature efficiently to take down bosses or a horde spawn. In addition, this gun can come in handy when trying to hit what is behind the main door in the initial stage during Zombie Pods.
This gun is extremely effective against Shielders since the trail will just go straight to their shields.
