By The Book 50G
Complete 100% of all main mission constraints.
I dislike these, it's like you want to do it the first playthrough so much you are following a guide! You feel dictated on how to play, no fun.
Committed To The Cause 20G
Reach level 55 in Multiplayer.
Easy for me, I enjoy the MP on AC3 I was prestige 2 or 3, but since it's bumped up to level 55 for the achievement, wonder if the highest is now 100 before you prestige.
All Rounder 20G
Play on every game mode, and use every ability and ranged weapon once in Multiplayer.
Mode is ok, ranged weapon is ok, but some abilities suck, guess I will only use certain abilities I never use normally in a noob lobby.
Master Of The Caribbean 20G
Complete the Discovery Mode of Wolfpack in Multiplayer
Wolfpack is back, great mode expect some stupid players have no clue and rush kills.
