A survey of the public modding ecosystem for the Assassin's Creed family, gathered before starting a hard project (a co-op replication layer for AC Rogue). The headline: **the tools exist and are strongest for AC Unity and AC4/Rogue, but no public co-op mod exists for any AC game.** Use this to pick a title and a toolkit instead of rediscovering the…
In single-player Black Flag we found the character's authoritative world-transform object, proved writing it moves the character, then picked an ordinary crowd character and drove it from UDP packets so a second "player" visibly walks where the peer walks. Verified in-game: a fake peer script made an NPC circle the player, and the NPC returned to its own…
none in single-player; the co-op link is the plugin's own peer-to-peer UDP, not Ubisoft's servers or online services; AC4BFMP.exe only studied statically, never run or injected

Debugger-attached game dies on a breakpoint that looks unknown.
A hardware write breakpoint on the visible position never fires.
Fields past the object's allocation size are other objects.
Writes snap back when the character is moving.
Quiet-looking bodies that accept writes but never render.
A game that "pauses" the world when unfocused.
Kernel-held UDP ports.
PowerShell name collisions broke our scripts repeatedly
Goal: a co-op replication layer for AC4 Black Flag — two players in one world. This note covers the part that is **verified working**: a 32-bit ASI plugin that loads into the single-player exe and reads the player's live world transform, plus the camera→target→**player body** chain found by a runtime probe. The avatar (a second, drivable character) is…
Goal: free-roam co-op in AC Rogue (Steam). The engine is Black Flag's AnvilNext **minus the MP binary**, so co-op must be synthesised, not unlocked. Working in-game today: reading the player's live world transform and streaming it over UDP (verified). Not yet working: a visible remote avatar — this note records the internals found and the dead ends so…

AI エージェントで Assassin's Creed を MOD しても安全？
シングルプレイ、オフライン、自分で立てたサーバーにとどめ、先にセーブをバックアップし（エージェントが um backup を実行）、ゲームファイルは決して配布しないこと。このゲームについて記録されたアンチチート：none on the single-player titles; do not mod online/multiplayer clients。
