As deadly as he is, Zack probably doesn’t need any Vigors for fighting. However, he might end up needing the Shock Jockey to power up certain machines.
Looking forward to the next chapter.

Giving a Spartan-III vigors would increase the survivability if against Covenant. That being said ONI would have a field day trying to understand them. At this point even with SPI armor nothing fired in Infinite is getting through the plating so the only possible dangers would be explosives and maybe the Security Automatons and the Handymen. I'm pretty sure a III could handle most of the regular enemies of Columbia.

Now we’re getting into the action.

Pretty good stuff, since zack is a spartan he probably will on full health way before booker even comes to Columbia, will Elizabeth even be in monument island by the time booker gets there?

Glad to see you updated the story! I was getting scared you wouldn't. Only advice to give feedback wise is to make sure you don't have Zack crack too quickly. After all, 6 years of spartan 3 training isn't going to go away just due to some inquisitive girl, at least not after a week. :)

well the spi armor was made for stealth but now its in 1904. between 1904 and 2500 their is no dought refinment in bullet craft with better metalergy for the bullets and better chemicals for propellent. the same calliber bullet and propellent load are no dought weaker than 2500 era bullets. best way to describe it is black powder to gun powder. while weaker and slower they still pose a threat so i can see spi armor bouncing pistol rounds and since automatic weapons of 1904 used pistol rounds. while not hard it would be unplesent to be fired at. anything bigger would pierce it.

nice

Love the characterization of zack so far, being very cold and analytical, just as I imagined. Only gripe so far is that tongue in cheel reference of songbird getting a copy of the Ghosts of Onyx, it felt a little out of place. Other than that though the story's excellent. Really hope to see this get updated...

This seems pretty good so far. Keep it up.

Yeah I was wondering that I thought all SPI armor had energy shields. it's just that they where weak as shit and could pop from a single plasma bolt.

never knew only headhunter teams had that.

also if I remembered correctly Noble team was equipped with Mark V B armor made by some random wrapon systems company for the Spartan llls

You need to keep writing this. The story is really interesting so far (especially as a person who never played any of the Bioshock games) and, besides a few easily correctable typos, it is very well written.

Can the magnetic repulsive field stack with the SPI’s energy shields? Or has this SPI model not been upgraded with shielding?

Interesting, I want more please.

WOW. Seriously. Not enough fics involving S-III's get typed at all much (even rarer are the ones about the Headhunters), which is seriously a bummer. So far, you've seem to have captured the S-III's personalities just right. Hopefully, Zack will be a tough nut to crack (but not infuriating), in terms of that pairing you tagged.

I really like the crossover with Infinite. Especially the inclusion of the multiple realities and time travel fuckery that happens. Now, I don't read Bioshock fics at all but I think I can safely assume that most authors fail at capturing the character's personalities. Speaking of which, Elizabeth. I've only run through the Infinite twice, so, pardon the lack of lore. But what I can remember and a quick search on the Wiki, is that Elizabeth is 19-years-old. when Booker busted in and Zack is 12/13/14-years-old...

Don't know if you're planning for the story to kick off with them in Infinite timeline or when Elizabeth is 14-years-old. But if you're gonna have Elizabeth and Zack at 14 then is that the "slow burning story" you were planning until Booker comes in 5 years later? Actually... that would kind of make sense since Zack has to heal from getting fucked up then train, and gather info in a confined room.

Well, other than that only problems are just the spelling errors. Not that many grammar issues but they're still there. Just a tip! If you don't have or want a beta reader then please re-read the chapter after a break from writing. Might not get all errors but would definitely increase the quality for your readers.

Other than that, looking forward to the future chapters, my dude!
