It's already starting, you have stuff like Fuso Knives or Confederate Eagle. There probably will be more. There is even a possibility of introducing some country-specific enemies too.
I won't make it with the Deep Ones this edition, I'm franticly trying to release the updated-globe version asap, as this feature is awesome and arrived pretty much unexpected. There will be a short summary of each country, unlockable through interrogations/Data Discs (with a +100 score bonus for each)... which I need to write first and that's not a 5 minute job.
Also there was something else due for overhaul first: armors. Hover, Defender and Assassin have been taken off the store and now are a part of the research tree (as an intermediate step between green armors and the good armors). Pros: they're cheaper and have better stats. Cons: require research, manufacture & some resources. And there is a 4th blue armor now: Stormy (lighter, flying Defender with a good movement bonus).
A new special ammo for selected firearms has been introduced: MAG ammo, which halves the clip size but adds extra half damage.
I'll also try to fit in special missile launcher munitions (bigger rocket, buckshot & AP rocket) and maybe some new weapons too.
The default weapon accurate autofire range will be raised from 7 to 9 as autofire seems to be underused with non-dedicated weapons.
