Are Assassin's Creed multiplayer achievements still obtainable?

No. The servers for Brotherhood, Revelations, and AC3 are shut down, making their multiplayer achievements impossible. Black Flag's multiplayer servers are barely active, so those achievements are nearly impossible as well.

Why is collecting flags in the first Assassin's Creed so difficult?

The game does not include map markers for the flags, forcing players to look up guides or search every corner of the map manually.

What makes Valhalla a difficult game to complete?

Valhalla has an overwhelming amount of side content and collectibles that can take around 300 hours to finish, and its mastery challenges are very difficult to complete.

Which mission specific objectives are the most frustrating?

Users frequently point to getting full synchronization in AC3, especially during the Charles Lee chase, and completing the no damage tank mission in Brotherhood.

The Most Grueling Achievements in Assassin's Creed

The hardest achievements in the series fall into three categories: multiplayer objectives, tedious collection grinds, and demanding mission specific tasks.

Many multiplayer achievements in games like Black Flag, Brotherhood, Revelations, and AC3 are nearly or entirely impossible to get now because servers are dead or shut down, making full completion unattainable.

On the single player side, players often cite collecting every flag in AC1, finding every chest in Unity, getting full synchronization in AC3, completing the tank mission in Brotherhood, and earning gold on Valhalla's mastery challenges as the most frustrating hurdles.

The hardest Assassin's Creed achievements are often those requiring multiplayer interaction or extensive, tedious collecting, but Valhalla's Mastery Challenges and AC3's full synchronization objectives also pose significant difficulty.

Multiplayer and Server-Dependent Achievements

Black Flag's Multiplayer Trophies: Many Users cite the multiplayer trophies in Black Flag as nearly impossible due to low server populations. "Black flag , multiplayer servers are barely alive"

Brotherhood, Revelations, and AC3 Multiplayer: Achievements tied to multiplayer in these older titles are now unobtainable because their servers have been shut down. "Brotherhood, Revelations, and 3 all had the multiplayer servers shut down so you can’t do anything related to that"

Unity's Coop Achievements: While not entirely impossible, finding players for cooperative missions in Unity can be very difficult, especially for specific achievements like reviving teammates or performing sync kills. "I need the revive someone who’s downed and 10 sync kills. I need people to get those achievements."

Tedious Collection and Grinding Achievements

AC1 Flags: Collecting all flags in the first Assassin's Creed is frequently mentioned as one of the most frustrating due to the lack of in-game map markers. "First AC, finding all the flags. They aren't marked in the map so you have to look it up or search every square inch of the game and die of old age."

Valhalla's Bloated Content: Valhalla is often cited as a game with an overwhelming amount of collectibles and side content, making 100% completion a massive time sink. "Valhalla without a doubt. It's way too long and some of the challenges are difficult. We're talking like 300 hours"

Unity's Chests: Collecting all chests in Unity is described as mind-numbing and extremely tedious. "Collecting all the chests was the most mind numbing achievement I’ve ever done in a game."

Challenging Mission-Specific Achievements

Valhalla's Mastery Challenges: Several Users identify getting gold on every Mastery Challenge in Valhalla as exceptionally difficult, with some individual challenges being particularly frustrating. "Valhalla mastery challenges are probably the hardest single achievement"

AC3's Full Synchronization: Achieving full synchronization in Assassin's Creed 3 is often highlighted for its demanding optional objectives, particularly the "chasing Charles Lee" sequence. "Probably getting full-sync in AC3. The majority of the optional objectives were a bitch to complete."

Brotherhood's Tank Mission: The tank mission in Brotherhood, especially when attempting full synchronization (no damage), is notoriously difficult and a source of frustration for many. "The tank mission in Brotherhood when going for full synch drained my soul…"
