The good news is that this achievement isn't nearly as daunting as it seems. The bad news is that you can't hack into terminals, increase your health capacity, use psionic powers, mimic into locked rooms, repair objects, or increase your inventory.
I would very strongly suggest doing this achievement on your last playthrough, as at this point you can easily know the layout of Talos I and get things done quickly and efficiently.Requirements
- "No Needles" is exactly what it sounds like. No needles allowed. You CANNOT install any neuromods, whether they're Typhon-based or Human-based.
- It may be okay to install a few for a power-related achievement and load the save back to having no mods installed, but if you actively install a neuromod and continue with the game, you will NOT get the achievement during the final cutscene.
- You CAN use Psychoscope chipsets and suit chips, but only two at a time. I'd recommend the Artax Gen 1 chipset, as this will increase the longevity of your suit's boost capacity and floating time.Loadout
You'll only be able to upgrade your weapons in the first slots of their attributes, meaning that you'll only be able to spend 4 weapon upgrade kits on each gun instead of maxing them out. Even then, they're still pretty damn useful against the Typhon.
• GLOO Gun
: Since you won't be able to repair control panels with spare parts or hack into terminals to activate grav shafts, the GLOO will be your main method of traversal in high places throughout Talos I and will add a neat little platforming angle to the game.
: You can pick this up as soon as you start the game. Extremely useful for fighting off Mimics and Phantoms, which are enemies you really don't need to waste your ammo on.
• Golden Gun
: Can be obtained from Jada Marks' safe in the Crew Quarters by doing the "Golden Gun" sidequest. The Golden Gun is an upgraded version of the Silenced Pistol that does considerably more damage and is all-around a better weapon. It's considerably overpowered, meaning that you can take down Phantoms, Weavers, and even Nightmares in less than two mags.
• Disruptor Stun Gun
: I'd strongly suggest this for dealing with corrupted Operators and Technopaths, both of which are enemies who have a tendency to do massive amounts of electronic damage and kill you quickly. It should be mentioned that the Stun Gun works all ALL types of enemies in the game except for Nightmares and Cystoids, so if you want, you can just stun a Typhon and whack them to death with the Wrench.
• Typhon Lure
: Makes the Typhon ignore you for a good while. Helps with bum rushing through areas and distracting Nightmares.Strategy
- Unless it helps you get a new piece of gear, avoid side quests and stick to the main story.
- Search the station for as many weapon upgrades kits as possible to give your guns that extra bit of edge.
- Always loot any junk you find so you can recycle it into materials. Since you won't be using Psi hypos, Neuromods, or spare parts, you can still collect and recycle them. If you do this, you'll end up having way too much of every material, which means you can fabricate dozens of ammo boxes and medkits.
- Piggybacking off of that, always craft a bunch of medkits. Nothing is worse than being in the middle of a Typhon orgy and only have 54 health.
- Remember, you have a jetpack. A few double jumps can cover a lot of ground and get you out of a lot of trouble. You can also access hidden paths that allow you to avoid combat.
- Play on Easy or Normal difficulty. If you don't, that's okay, but I would suggest making this as simple as can be.
If you reach the final cutscene without having ever installed a mod, you'll instantly pop:
