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:
Yes, almost all of them are without proper names or descriptions, that is fluff to tack on at the end after the real work, which is adding them into the game, troubleshooting them, and then balancing them and adding them to NPCs and traders.
Some of them are without icons too, proper icons are in the game, but some of these weapons aren't re-adjusted to the proper coordinates in the grid yet.
Yes, these are new arm textures, no, they are not permanent and won't be in the final release.
Actually, recoil does seem a bit high on the 7,62 AKs. I'd have to try for myself though. With rifles that kick a fair bit I'd certainly consider carrying a SMG for a while like I did in LURK.
If I recall correctly, I uploaded this before did the work balancing recoil.
I may upload a second weapons preview just to demonstrate the differences between those types of rifles.
