Prey

Can you do this through the Escape Pod earlier in the game?

No as that's not classed as completing the game it's classed as failing the game

It's not working for me. I finished the game without acquiring any ability, the reloaded to get also this achievement, first acquiring Human abilities and then Typhon powers, but the achievement keeps unlocked.

@JetLagFox: That doesn't work. You have to do one full run with powers no matter what you do. This just lets you save out on doing a third one.

Fun fact - 159 neuromods to max out Typhon skill tree and 218 to max out the Human one.

Wait, so completing the NoNeedle run negs the one-side-only run?

no, run no needles and complete the game till it gives you the load option, releaod the save just before you do the action that proceeds to the credits, purchase some typhon abilities then proceed to the credits, then on a different campaign slot do an entire plathrough only purchasing human abilties, turns 3 playthroughs into 2

I did "only human abilities" on Campaign 1, and then "no abilities + only Typhon abilities" on Campaign 2. Two save slots. Managed to get those 3 achievements this way

Is there a % progress tracker on the achievement? I just completed a human abilities only play through and was expecting the progress to go up to 50% but it has stayed at 0%.

no there isnt a a progress tracker for this cheevo it will stay at 0% after first playthrough

Was literally going to ask the same question as Romanaround, thanks for that.

Didn't read the solution but luckily I did no needles, then reloaded w/ Typhon rather than Human so I could leave Human for my 2nd full play through.

How much easier is it with Human abilities btw? Significant?

The game with human and no typhon abilities is SOOOO much easier and faster than opposite way round

did you complete the game no needles, reload the game at the end purchase several typhon abilities, then ON A DIFFERENT CAMPAIGN play through the entire game start to end credit sequence with only typhon abilitie?

once you use a mod of either type it marks that campaign as that type even if you reload an earlier save E.G half way through game install a human mod then reload to before i installed the mod the save file will still be marked as human

well not that i approve or even recommend it apparently you can glitch to the end dont know if that voids the cheevo tho

My 1st playthrough was male good Morgan - Good human ending
My 2nd was female evil Morgan - Evil alien ending (I recommending doing it and no abusing the saves, its really fun)
My 3rd will be no needles

Asking the obvious question: Which are the Typhon Powers and which are the Human abilities? Combat focus is a human ability despite using Psi points, correct?

does “split affinity” need to be done on back to back playthroughs? Or does it just need to occur on two playthroughs in general?
For instance: I just completed a Typhon only gameplay, does this next one HAVE to be only human powers ? Or do I just need to do human only at some point in the future? Thanks and hopefully that made sense.

you just need one campaign slot to have human and one slot to have typhoon, you can do any play through between them without affecting the achievement

So I did a playthrough of acquiring human abilities then a playthrough after acquiring only Typhon powers and it didn’t unlock. Are you allowed to use your human abilities that you earned in the previous playthrough, or does it have to be a playthrough with only human abilities and then a clean playthrough with only Typhon abilities? Like can you carry you abilities over to the next playthrough?

you know when you start the game and it asks which campaign slot do you want to load 1,2 or 3, you must have one human only slot and one typhoon only slot. no new game+, completely seperate slots im afraid

Any suggestions for the Cargo Bay area if you've already unlocked Typhon skills but still want to save everyone? Set up turrets then run?

What a miserable achievement. This game has been a nasty ride, defintely not the best work from Bethesda here

To be fair to the publisher, this is on Arkane as there are similarly annoying "no upgrade" achievements in the Dishonored games too.

Fair point. It's just been a very long time since I needed such an intensive walkthrough because of such convoluted achievement requirements

Two years ago i did a no needle run and reloaded en used a typhon ability. I also made a start back then on a human mod run. Finished that one yesterday but no achievement. Decided to do a new typhon run just in case on a new game + file of the no needle run. Finished it and still no achievement. Safe to say im done with this games not doing a 4th run.

4th run, Jesus. I understand that

Finished campaign on slot 1 using quicksave/load method right before entering shuttle at the end; first time using 1 typhon unlock, reloaded after finishing, then did 1 human unlock. I understand that you need to finish it on 2 slots, but now I'm not sure which option to go for on slot 2, human or typhon xD will do quicksave/load at the end shuttle and update the thread to confirm if it unlocks once done, won't be too soon though

wif you purchased a typhoon unlock on save 1 before you reloaded and then did 1 human unlock that save file will now be marked Typhoon, so save slot 2 should be human unlock

Doing two run throughs is a reasonable approach. First campaign was with only human powers to learn the map and get most of the achievements including the collectibles. I even went back to an earlier first campaign save after finishing it to use my numerous neuromods to get all the Typhon power related achievements. Second campaign was with no powers until the end and doing the last moment save cheese for a Typhon power.

I managed to get the achievement from my "no needles" playthrough. If you're playing on the PC you can save right before the end (as suggested above). Copy the save game to a diffrent campaign slot after that, reload the save games from the two slots, choose a different human/typhon ability with each campaign, and finish the game. That's it.

If you don't want to do another full game run for this achievement, I did a no needles run using a combination of normal play and speedrunning, using this video:
https://www.youtube.com/watch?v=KQan-rIbKkA
I pretty much used the tricks to get to the lobby, then played normally until I reached the Arboretum. Then I used the video the get the nullware device quest, and just followed that quest until the end. Took me about three hours but it included a lot of random messing around. You're obviously free to pick up and try any tricks you're comfortable with. The ones I used I felt didn't require much skill or accuracy. I then reloaded the save to purhcase the typhon ability. This method should work for any end game achievement apart from"I and Thou" and "I and It".

Late to the party, but if you throw a few nullwave transmitters as soon as you open the door, that should essentially neutralise the Typhon's powers long enough for the turrets to do their work.

Additionally, if you've got the materials then you could just build more turrets then required (5-6 maybe) and that should do the job.

I got this today. First I did a No Needles & Awkward Ride Home playthrough on slot 1 and saved at the end before boarding Dahl's shuttle. Once the end credits started I quit the game and restarted. I reloaded my save and installed a few typhon mods, beat the game again, and watched the post-credits scene. Then I started a new game on slot 3 and beat the game with the nullwave transmitter using only human mods. The achievement popped before the credits appeared. This was all done on Story difficulty. Thanks for the tips everyone!

For future reference, I was able to use RA1NBOWGASM's technique with New Game Plus (added by the E3 2018 patch) and still get "Split Affinity." My playthroughs are listed below if anyone wants to take advantage of NG+, which is recommended because more neuromods means more fun.

Campaign #1: I finished the game while going for "No Needles" and unlocked that achievement. Throughout my run, I made sure to hoard as many neuromods as I could, and I made a save right before triggering the end credits.

First Reload: I loaded the save file that I had positioned seconds away from the game's end. I then installed a couple of random human skills and replayed the ending cutscene. This counted for the human playthrough of "Split Affinity."
Second Reload: I loaded the save file again, but this time I installed all of my neuromods. I only upgraded Typhon powers and replayed the ending cutscene. The plan was for the abilities chosen here to be carried forward with NG+.

Campaign #2: I selected New Game Plus and imported my save--the one with Typhon powers--from Slot 1. I chose Slot 2 for this new campaign. It's important to note that the only things you keep from your previous playthrough with NG+ are the abilities you bought, early access to your psychoscope, and your research (which are located in Morgan's office locker). All of your equipment and unspent neuromods are reset. In any case, I used my OP Typhon powers to cruise through the story. I hoarded more neuromods but made sure not to buy any human powers. When I finished this playthrough, "Split Affinity" unlocked.

...

In summary: I went with No Needles and used RA1NBOWGASM's technique to get human powers out of the way. I then used NG+ to make a powerful Typhon-based playthrough for the other half of "Split Affinity" instead of starting from scratch. Like in the original solution, you can do this vice versa if you prefer human powers to Typhon. In that case, you should buy a few random Typhon powers during your "First Reload" to get that requirement done. Then for the "Second Reload," spend all of your neuromods while carefully choosing your human powers. Afterwards, import your save with NG+ to start "Campaign #2" but with an OP human build.

Special note: I also recommend making a save near the end of Campaign #2. That way, you can reload after unlocking "Split Affinity" and spend all of the neuromods that you have hoarded a second time. This will leave you with a massively OP character for your third playthrough (NG++) and make mopping up those last achievements a breeze.
