The Callisto Protocol - All Collectibles on Maximum Security difficulty

This topic will guide you through the game while collecting all data logs needed for the logs trophy (only collectible trophy). It's done on Maximum Security difficulty, which is not that hard, but it will require some time to master it. 

Easy difficulty exploit (still works on 1.05 patch)

You can start the game on this difficulty and change to Easy mode after you get control - after you beat the last boss you can change diffiulty back to hard, save, load that save, finish the game as it gets saved after the last boss. My videos will not do that, the whole run is the hard mode, so I want to show how to do that. If they patch this exploit, be careful, on 1.05 version it still works.

This guide will leave timestamps and note everything important, and it contains the full gameplay including the scenes so you can enjoy the game while someone else struggles on hard difficulty :)

Hints for Maxiumum Security playthrough

 - Always carry 1-2 health recovers. Ammo (can be crafted), batteries (CANNOT be crafted) and sellable items. Do not spend your credits on needles upgrades
 - Upgrade melee first, then gun, shotgun and assault riffle. Upgrade left melee branch first, then 2 points in the right melee tree and 1 in the middle. There is a trophy for fully upgrading a weapon; you can save, upgrade, and load to save credits. Do not unlock last gun upgrades, they are not needed. Leave 3-4k for the end for bullets.
 - Avoid crafting "Skunk Gun" and "Tactical Pistol". If you pick up the blueprint, toss it from inventory before interacting with the station. Not unlocking a weapon means you will get bullets only for the ones you have
 - Always try to kill enemies with melee; It's easy when fighting single enemies - just hold left or right on your analogue on first hit, then the other direction and stop when enemy stops. Then attack couple of times. This saves bullets.
 - Be careful about log collectibles; If you die and it didn't auto-save, you must collect it again. Some pickups can be missed due to bugs, so always make sure to check if you have what you picked up
 - Repeating checkpoints can be used to grind "kill" trophies. It stacks up, so you can find a good spot and farm miscelanous trophies
 - There is no NG+. You need to collect all logs, which are collectibles; in just 1 run. This makes everything missable. Keep backup saves on chapters.
