The Callisto Protocol: PS4 and PS5 trophy and platinum guide

PS4 / PS5

The Callisto Protocol’s platinum is mainly a matter of organising your run: keep the required difficulty, track collectibles as you go and concentrate credits on one weapon. Do not mistake trophies added after launch for base-game requirements. Updates introduced New Game+, so early roadmaps saying it does not exist describe the launch build. This route prioritises a carefully managed campaign, checking Data-Bios after collection and keeping separate saves before irreversible transitions.

Base-game platinum roadmap for PS4 and PS5. New Game+, Hardcore, Contagion, Riot and Final Transmission trophies are separate from the platinum.

Required difficulty: Maximum Security for The Protocol is About Life; this is not Hardcore.
Missable trophies: Watch Data-Bios and optional opportunities before leaving an area.
Online: No multiplayer trophies in the base-game platinum.

Update the game and select the right mode

Install updates before starting. Dismemberment Mode disables campaign trophies, so it is not a shortcut for Maximum Security. Select the standard campaign and retain its completion save if you want to use New Game+ later. A lower-difficulty practice run can help you learn, but keep it separate from the run intended to fulfil the difficulty requirement.

Check the mode and difficulty before your first save.

Build a reliable Maximum Security run

Complete the campaign on Maximum Security for The Protocol is About Life instead of relying on old endgame difficulty-switching exploits. Separate ordinary dodging from perfect dodging: surviving a fight does not necessarily register the timing required by the trophy. Practise against an isolated enemy and use the campaign’s accessibility options without enabling the mode that disables trophies.

Keep Maximum Security throughout the run chosen for the trophy.

Check Data-Bios before moving on

Grim Reaper is the main collection checkpoint. Account for implants harvested from bodies as well as audio logs; confirm each item is registered in the menu and inspect its content. After a death, check items collected since the last checkpoint again. Updates moved some logs, so compare the area and item name rather than following only the exact position shown in a launch video.

Keep a separate save at the beginning of a chapter and check the menu before leaving the area.

Focus credits on one weapon

You Need a Gun requires a fully upgraded weapon, not numerous upgrades spread across different equipment. Choose one firearm to finish, check its remaining upgrade branches at the Reforge and plan subsequent spending around that goal. New Game+ can restore weapons, upgrades and credits at the first Reforge, but it does not replace checking your collectible progress.

Finish one weapon before investing in optional upgrades for several others.

Separate the GRP combat tasks

GRP trophies require different actions: grabbing enemies, using environmental hazards, and combining GRP with melee. Decide which action you are targeting before spending its charge and locate an arena hazard. Avoid practising perfect dodges while also juggling several targets and a throw: separating the challenges makes it easier to identify which requirement remains.

Check for the unlock after a successful attempt, then change targets.

Finish the base game before additional content

Compare missing trophies in the main group against your saves before starting another campaign. New Game+, Hardcore, Contagion, Riot and Final Transmission have separate objectives: completing them can raise the overall completion percentage, but they are not mandatory steps for the base-game platinum. Keep your completion save rather than overwriting it while testing another mode.

Separate the base trophy group from later additions.

Trophies to watch

You Need a Gun

Fully Upgrade One Weapon

Frequently asked questions

Does New Game+ exist?

Yes. Official updates added it, and it requires a completion save. Its additional trophies should be separated from those required for the base-game platinum.

Can I use Dismemberment Mode for the platinum?

No. Official patch notes state that this mode disables campaign trophies. Do not confuse it with individual accessibility settings.

Why is an audio log not where an old video shows it?

Some updates moved audio logs. Check the name, chapter and menu entry; if your checkpoint predates collection, pick the log up again.
