Assassin's Creed IV Black Flag

Fastest way to get to level 55 is to play Wolfpack solo. Does not require to play with others.

When you first start playing you will naturally be lvl 1 and have a default set. You can simply switch Money Bomb and Disguise around.

If you are new to this mode, Discovery mode is basically the tutorial for Wolfpack mode, and can be accessed at anytime through the Wolfpack Multiplayer menu, however the first time you start up Wolfpack it will ask you if you want to do it, so it can't be missed.

You must be level 48 to unlock everything.

A bit misleading achievement - you do not require Jaguar to get the achievement, simply get highest round in domination (even if you are not jaguar) will get you the achievement. But jaguar has to be in the game

Choose Wolfpack Mode - private - Saint Pierre - Standard.
Choose Blackbeard, dont forget equip your pistol (unlocked at Level 38)

You can unlock this during a manhunt match when you are a pray. Throw a booby trap at the Chase Breaker, run up it and wait for the pursuer to follow. After he runs to it blow it up and achievement should unlock.

It does not unlock in private matches and you have to be level 26 to unlock trap.

at level 28, you unlock Sabotage. It's a ranged weapon. Add it to one of your ability sets, then either find a boosting partner or do it solo in Wolfpack mode on Prison.

You don't need to use the Game Lab to get this achievement. Just go into the Custom Match menu and set session type to Game Lab and Matchmaking to Public, then wait to find a game.
