The Zone of Alienation mod is an adaptation of the renowned AMK mod. It is built on top of a specialized variant of AMK that uses a magazine system. From this premise, it has expanded to aim to include the following:
Testing grenade types RGK-60RD, (tear gas hand grenade,) and Gvozd 40mm caseless tear gas grenade.
Both have had their damage dialed in just enough to maim opponents without killing them, but their effectiveness depends highly on what armor the enemy is wearing.
Overall, they offer a different option for clearing rooms in a subtle manner, as opposed to fragmentation grenades.
