Hi guys & girls - I've finally managed to get the Professional Syndicate done & unlocked the .300 knockout. Takes some getting used to it must be said but it is an awesome powered sniper, my next goal is to unlock the medic one now so this should be fun. If you guys need any help in getting the .300 knockout I'm online most nights after work (depending what shift I am on) and Sunday's I will be on after 5:30 BST...
In order to unlock the syndicate for the .300 you must have completed both assignments for the professional class (which can be found on battlelog) once the assignments have been completed you must obtain 10 bronze 10 silver & 10 gold stars during gameplay (I got confused at first) don't get me wrong can be a bore selecting the one class every time but it will be worth it in the end...
Once this his has been achieved the syndicate will then become available unlocking the Mac.10 sidearm, as soon as the syndicate is unlocked you will have to do the following:
Obtain 200 Sniper Kills (Body, Head, Arms) wherever on the enemy player as long as you kill them,
Obtain 15 Marksman Coins (Headshots from a distance)
Obtain 15 Camera Coins (easily done unless other players have placed cameras near by)
And last but not least unlock the tier 4 for the professional in 10 separate games, this can be done a lot more quickly with the help of the boosts that you will have no doubtedly unlocked from your battlepacks mainly use either the Objective or Reputation as they will help you jump from 1 to 2 in a matter of seconds depending on how you've killed your enemy.
Sorry for the essay - but if I can help people unlock the .300 Knockout then I believe I've also achieved something as well...
