Prey

Spend collected Neuromods to unlock abilities

You need the human Hacking ability for this.

You need to acquire the Human ability "Combat Focus"

You need the Psychoscope to get started here, awarded as you go through the story.

"You used the Psychotronics satellite to dismiss or summon the Typhon Nightmare." There's a giant typhon called Nightmare, after you defeat it a few times you get a sidequest from January you can use to dismiss it - but this only happens if you have been installing Typhon Powers!

You need to acquire the Typhon ability "Mimic Matter", which you can get by scanning two (alive) Mimics. You don't need a high level of the ability to get enough objects.

You need to acquire the Typhon ability "Mimic Matter", which you can get by scanning two (alive) Mimics. You can only get this when mimicking a mimic that is mimicking something. Installing the "Mimic Detection" chipset will make this easier.

Deep Storage in the Cargo Bay is sealed behind a voice lock keyed to Danielle Sho. Track down a recording of her voice (found via her belongings/workstation as part of her sidequest) and play it at the voice console to open it. If you can't find her voice sample, chase her sidequest thread first - it points you at it.

"You rescued Dr. Igwe from a cargo container." When you get stuck out in space you'll get a distress call from Igwe who is stuck in a container. Don't open it - note its number (2312), and use the number on the computer in the Cargo Bay. The container will dock itself and Igwe will be saved!

You can't get this if you have the "Recycler Shielding Suit Chipset" equipped.

"You helped Igwe, January, and Mikhaila meet in your office." You need to have saved Igwe (see "Adrift") and Mikhaila (see "A Friend in Need"), and also not killed January (see "Suicide by Proxy"). Eventually they will all call you and suggest a meet

"You killed January." Save the game before doing stuff when January appears and introduces themself in your office. Then reload - its handy to have January later in the game, and also for "Brain Trust".

Upgrade kits are relatively rare, so stick to one weapon and only upgrade that to make sure you can fully upgrade before the end of the game.

"You found Gustaf Leitner's Connectome for Dr. Igwe." You need to have saved Dr Igwe (see "Adrift")

Dr Howard's Superfruit is special and obtained as a reward for completing the "Gardening Tips" side mission. That makes 40 types total... ...of which you only have to eat 39. So you can miss one... Look around everywhere, and loot everything, as you go through the game to make sure you get all these.

These are the recordings your pre-amnesia self left dotted around Talos I - collectible TranScribes and audio logs from the old Morgan. Grab and listen to each as you sweep the station; several sit in earlier areas that get awkward to reach once the endgame limits your backtracking, so don't leave a zone without checking. A collectibles list is the safe way to make sure you've got the full set.

You can check whether this is still valid for you in the stats menu; the "Humans Killed" figure should remain zero. Only humans dying by your hand count. Other causes of death (including inaction allowing them to die) are fine. Ignoring quests for saving people is fine. When you have to kill the cook, he will die of blood loss if you disarm the Recycler Charge - still fine!

Save everyone (specifically, Aaron Ingram, Igew, Sarah Elazar, Mikhaila and Alex). Make sure you don't achieve 'Psychopath' status. You get empathy points by saving these people, completing their missions, and for saving 10 mind-controlled humans. You lose empathy points for killing those named people, or allowing them to die.

"You found all the smuggler's dead drops." Sidequest from a body near the lift once you get to the Arboretum.

Yup, two full playthroughs!
