Betrayer; I like the idea of future tech in the old world... but don't love it, it doesn't really seem fair you upgrade your armor to get the upper hand ending with a long dragged out battle for a lucky hit, to one hit kills... not saying completely get rid of the tech, just ease up on the future advantage stuff, other wise it kills the Medieval vibe.
Well, the recent thing with the densified armor was just a one-time thing. Manfred looked over the strength, agility, magical power, and other statistics of the planet's average denizens, and gave the two an appropriate upgrade to their armor and weapons to even the odds. They will not advance any further.
About the guns, the matchlock arquebus was deemed too clumsy for the mission, and was replaced with the more reliable but still fairly primitive and single-shot falling-block action firearm. The caliber and velocity have not changed. I briefly considered bolt or lever-action, either with paper or metalic cartridges, but that would enable rapid fire and would be very unfair.
Regarding the hand grenades, there is a weapon called Greek fire that was used by the Byzantine Empire over a thousand years ago. One use of it is kind of like a Molotov, and is a ceramic jar wrapped with a burning cloth and filled with flamable compunds, which are derived from petroleum, plant resin, and other things. The ancient Chinese made hand grenades too, in addition to their early firearms, rockets, and flamethrowers.
And finally, on the subject of DeNihil's Augmentations, which is probably what you're really concerned about, he has had many disabled already. I'll list all the ones that have been left on for the sake of uniqueness, and those that have been turned off for the sake of RP balance, blending in, adhering to Subjugator doctrines, or simply excluded because they wouldn't benefit an Android. There are also some that I'm not sure of yet, and would like to ask about your approval or disapproval of. There may be some redundancy due to copying information off of the Deus Ex Wiki.

I think that's all of them, and I think I got everything placed right. Feel free to ask me anything about why certain things are enabled or disabled, or whatever... I'm really tired now, so I'm signing off and returning later after I get some sleep.
Look at these if you want detailed info on any of these Augmentations. Use Ctrl+F to quickly find things you might be interested in, like "Biotox" or "Wayfinder."

The Undecided list is a lot shorter, and most things that were there before are now in the Disabled/Excluded list. I've also added footnotes for some things.
* These Augmentations were left on due to A: The complete lack of computers and machines on this world, and B: It'd take time to reinstall the software and/or hardware.
** These Augmentations are obsolete next to basic Subjugator military training.
*** These Augmentations are against Subjugator law and were never installed.
