PS4 / PS5
Back 4 Blood first requires a survival-ready team or deck, not merely a faster sprint to the saferoom. Updates added offline campaign progression; launch instructions excluding all solo progress no longer describe the whole game. This does not remove the list’s online requirements. Treat Nightmare as a checked sequence of maps, reserve pacifist conditions for dedicated attempts and verify Swarm and the Fort Hope party separately.
PS4 and PS5 base list, Acts 1–4. Additional acts, hives and DLC No Hope trophies are not required for the base platinum.
- Required difficulty: Base acts require completion on Nightmare.
- Missable trophies: Maps can be repeated; verify each map at the required difficulty.
- Online: The updated campaign supports offline progression; Swarm and party requirements remain online.
Build the deck before Nightmare
Use a more manageable setting to learn alarms, events and forced defence points. Choose cards consistent with your role and main weapon instead of collecting bonuses you never use. When a section repeatedly fails, identify whether the problem is damage, crowd control or survival; that distinction tells you what to change in the deck.
- Define the deck’s weapon and role before the difficult run.
Check maps across all four acts
An unfinished act may hide one skipped map or a completion not recorded on the required difficulty. Keep a completion checklist rather than rely on remembering the boss. When resuming a run, verify its starting point, mode and difficulty before investing time in an already finished sequence.
- Confirm every Nightmare map in the completion summary.
Use the updated offline campaign
Offline campaign progression is distinct from the original launch training mode. When playing with bots, select the correct mode and verify expected progress after one map. Do not extend this feature to every trophy; a Swarm victory belongs to another system and cannot be replaced by finishing acts with AI teammates.
- Distinguish offline Campaign, training and Swarm.
Dedicate a map to restrictions
For a pacifist or no-horde attempt, choose a familiar map and prepare the whole team’s behaviour. Weapons, attachments and automatic reactions may compromise a goal different from ordinary survival. Do not combine a delicate restriction with your first Nightmare attempt; test the specific condition in a controllable setting.
- Agree on the restriction before leaving the saferoom.
Finish Cleaners, secrets and online modes
The Cleaner condition concerns the original eight; an additional character does not replace a missing original. Record secrets by campaign section, avoiding DLC secrets when resolving a base-list gap. Check Swarm access and participants before organising the required victory.
- Track the original eight Cleaners and Swarm victory separately.
Trophies to watch
Act 1 Cleaner
Complete all Act 1 maps on Nightmare difficulty.
Verify every Act 1 map on Nightmare; reaching its ending alone does not account for skipped maps.
Grateful Eight
Complete a mission with each of the original Cleaners.
Finish a mission with each original Cleaner and record the character used.
Swarmed
Win a game in Swarm Mode.
Win in Swarm Mode; the offline campaign does not satisfy this condition.
Frequently asked questions
Is offline progression still impossible?
No. The December 2021 update introduced offline campaign progression. It does not remove every online trophy.
Is No Hope mandatory for the platinum?
Not for the Acts 1–4 base list; check Nightmare. No Hope conditions in additional groups belong to DLC.
Do added Cleaners replace the originals?
Not for Grateful Eight; its description requires original Cleaners. Check which have been used in a completed mission.
