In 4.0/Unturned II, there should be certain tool’s that are hard to craft and can potentially command zombie’s. This could range from very minor thing’s like rock’s to the smoke’s and thing’s we all know and love in 3.0 to full on devices that could link up to zombie’s like “zombie communication device” , which could link up 25 zombie’s at a time and make them more powerful. These zombie’s will have blue marker’s over their head OR blue eye’s, with orange eye’s at night. This link allow’s the player to use emote’s like “point” to move zombie’s to a certain location or attack a certain object as well as thing’s around it. “Surrender” could summon the zombie’s to come and attack all thing’s around you. “Wave” could make them come to you. “Rest” would make them all crouch and become running zombie’s temporarily and “salute” causes all zombie’s to stand, not defend themselves or anything, and slowly regain health+it will make them salute and look at you. Facepalm will cause all zombie’s to die. The “Zombie Communication Device” will use material’s that never respawn and are found in hidden area’s.
However, we also have the devices most player’s will start using when they first start to move zombie’s, the original 3.0 smoke’s, flare’s and my suggested addition, low damage dealing high noise rock’s.
But, for mid-tier player’s, we would have other craftable item’s. These could be thing’s like “zombie link device” which temporarily allow’s 15 zombie’s to be controlled the same way.
