Assassin's Creed III Remastered Completionist Trophy: Full Requirement Guide

Everything the Assassin's Creed III Remastered Completionist trophy demands: full sync missions, side activities, collectibles, and cleanup tips.

Of all the trophies on the list, the Assassin's Creed III Remastered Completionist trophy is the one that decides whether a platinum run actually finishes. It demands 100% synchronization across the campaign, every optional objective, every side activity, and the entire collectible set — a combination that turns a short story run into a 40–50 hour project, according to the TrueTrophies estimate. This guide breaks the Assassin's Creed III Remastered Completionist trophy requirements into checkable chunks, so nothing quietly slips past you at 95%.

What the Completionist Trophy Actually Asks For

The trophy is not one hard challenge — it is a long tail of small ones. According to the requirement list maintained on TrueTrophies' Completionist trophy page, unlocking it means hitting three separate conditions:

  • 100% sync on every main story mission, which means completing the optional objectives as well as the primary ones
  • 100% sync on every side mission, across a wide spread of activity types
  • Every collectible and completionist extra, including crafting, upgrades, recruits, and shop purchases

The page tags the trophy as Single Player and Offline Mode, so the Assassin's Creed III Remastered Completionist trophy does not require any online services to unlock. It is flagged as an Ultra Rare trophy on PSN. As of 2026-11-10, that same TrueTrophies page displayed unlock percentages of 22.11% and 1.80% for the trophy, and it logged its first winners on 1–2 April 2019.

If you want to check the game itself before committing, the Assassin's Creed III Remastered Steam store page is the canonical listing.

Mission Requirements: The Full Sync Checklist

This is the biggest part of the grind, and the easiest to underestimate because "side mission" covers a lot of ground. Here is the mission and contract breakdown as listed by TrueTrophies.

Mission typeWhat you need
Main storyAll main missions in Sequences 1–12, with every optional objective
Epilogue3 epilogue missions
HomesteadAll Homestead missions, except the Encyclopedia of the Common Man set
Naval4 naval missions
Privateer12 Privateer contracts
Courier3 courier missions — one in each city
LiberationComplete each available district's required ambient Liberation Missions and closing recruit/contact memory; Boston Central's Stephane recruitment is story-linked
Peg LegCollect 24 trinkets, then complete 5 Peg Leg missions
Templar Forts7 fort liberation missions
Assassination contracts3 — Boston, New York, and the Frontier
Delivery requests8 total: 3 in the Frontier, 3 in New York, 2 in Boston

The delivery requests are the classic missed category, because they are easy to walk past and there are only eight of them scattered across three regions. If you are hunting the Assassin's Creed III Remastered Completionist trophy, screenshot this table and tick rows off as you go.

Challenges and Side Missions People Overlook

Challenge chains sit underneath the mission list and are split into levels. Three of the four societies also attach side missions on top of their challenge tiers — the Thief challenges are the exception, with challenge levels only and no associated side missions.

Challenge chainWhat you need
Boston Brawlers3 levels of challenges + 7 side missions
Frontiersmen3 levels of challenges + 6 side missions
Hunting Society3 levels of challenges + 6 side missions
Thief challenges3 levels of challenges only

Because these are tiered, they reward starting early rather than saving for a final sweep. A challenge you begin in Sequence 3 will often finish itself while you do other content; the same challenge started after the credits means farming kills, races, or hunts with nothing else to show for it.

Collectibles, Crafting, and the Money Sink

The non-mission requirements are where the Assassin's Creed III Remastered Completionist trophy becomes a bookkeeping exercise. Every item below appears on the TrueTrophies requirement list.

RequirementDetail
Almanac Pages36 across Boston and New York
Feathers50 across the Frontier
Peg Leg Trinkets24
Treasure chestsAll of them — chests found inside Peg Leg missions do not count
Almanac inventionsCraft all 9
Aquila upgradesObtain every upgrade for the ship
Assassin recruitsAll 6 recruits leveled to maximum, Assassin — Rank 11
General Store weaponsPurchase every weapon, totaling £72,554
Underground fast travelAll 21 entrances found and opened — 10 in Boston, 11 in New York

Two numbers stand out. The £72,554 weapon bill is the single largest currency gate in the list, so treat it as a budget rather than a shopping spree. And Rank 11 on six recruits is a slow burn that is best started the moment recruits become available, not after everything else is done.

The underground fast travel points are worth opening early for a different reason: they make every later cleanup lap through Boston and New York substantially shorter.

Practical Tips for a Cleaner Cleanup

  • Read optional objectives before a mission starts, not after. Main story sync is required, and the optional objectives are the part that decides whether a mission counts.
  • Do collectibles region by region. Clear Boston's almanac pages and underground entrances together, then New York's, then sweep the Frontier for feathers and trinkets.
  • Front-load the challenge tiers. Start Boston Brawlers, Frontiersmen, and the Hunting Society early so their tiers complete passively.
  • Bank money toward the General Store. £72,554 is a fixed target, and knowing the number makes it easier to stop spending elsewhere.
  • Keep a written checklist. With this many parallel categories, memory is the real enemy late in an Assassin's Creed III Remastered Completionist trophy run.

Player experience on trophy trackers consistently points to the same pattern: people finish the story at high completion, then discover a handful of delivery requests, chests, or challenge tiers they never touched. A checklist from the start closes that gap.

FAQ
