Crossing The Line starts out in Bangkok and takes you to New York and Italy. Overall it's not that bad and most should be able to complete it in the 9+ days still left. Find the Mission on your Mission Bar or your Home Page Current Events Module.
Part 1
Overseer
Getting support from your mafia in Mission is a pain in the ass. It takes forever. Use the Mission Crew Link bookmarklet by Team Spockholm to generate a link you can post in your news feeds. You only need 5 so it shouldn't be a problem.
Looting 12 Hung Chu Enforcers was a little more difficult. The drop in Episode 3 of Bangkok while doing the job "Hire An Unsavory Crew". The job costs 72 energy if you have fully mastered the Pirate Episode but the drop rate could be better. It took me about 7,000 energy to loot them all.
If you're curious like I was, the
Hung Chu Enforcer was a Bangkok Crate item offered in the Marketplace about a year and a half ago. The stats suck but you can still buy them for 2 Reward Points each.
The loot reward for completing Part 1 is 3 Protective Shirts. They really should add a decline option for loot rewards that suck.
Part 2
The Mark
There isn't much to do in Part 2. Go to Episode 2 of Bangkok and do the job "Receive a Kickback From The Buyer" 10 times. You will spend 1,000 energy if it's fully mastered.
Now loot 12 from fighting in Bangkok and you're done. There are no loot rewards.
Part 3
The Fast Lane
You need to rob 8 Chop Shops. You can do so from the robbing board or rob an individual from their profile. I laughed when I read "Rob 8 Chop Shops In New York". I wasn't aware that there were Chop Shops in other destinations.
Fight 16 opponents in New York and collect on your own Chop Shop two times. There is a 18 hour timer on collection intervals so plan accordingly.
The loot rewards are more of the same. The stats are mediocre and won't help many players. You get two Car Cutters and two Red Scorpions.
Part 4
Encore
Rob 8 Auto Boutiques. Again you can do it from the robbing board or an individual robbing page. You do need to win for it to count.
Go to Region 3 of Italy and do the job "Smuggle Goods Through A Fishery 20 times. If you fully mastered this job it will cost 72 energy for a total of 1,440 energy to complete the task.
Collect from your own Auto Boutique 2 times and you are done with Part 4. The Auto Boutique has a 18 hour collection timer. There are no loot rewards.
Part 5
Indulgence
Ask your mafia to send you 6 Satchels by clicking on the "Ask Now" button from the Mission.
If your mafia isn't responsive the first time around, you can ask again in 2 hours.
Go to Region 3 in Italy and so the job "Buy Out A Costume Shop" 15 times. It will cost 64 energy if you fully mastered it for a total of 960 energy. You can see below that somehow my job was reset. I hadn't completed the Fight or Social Paths so that's not why. I'm not complaining, I mastered the job again and got a skill point.
Buy one item from your post and you are done. There is a 23 hour timer between Port purchasing intervals so make sure you don't collect on it if you are close to getting to Part 5.
Finally a loot item that should help more players. You are rewarded with 4 Crystallines. They don't help me but the stats are much better than the previous parts.
Part 6
Small Fry
Ice 6 opponents in New York is easy. It looks like the fight list has calmed down and ices are easier to get now. Robbing 8 Mega Casinos was a little bit harder. Players are usually good about collecting them and they don't show up on the robbing board as frequently as the other properties. You can rob an individual robbing page and I used less stamina doing that.
Go to the Capo Tier in New York and do the job "Steak an Air Freight Delivery" until you loot 15 Metal Containers. The job only costs 28 energy and the drop rate isn't that bad so you shouldn't need to spend much energy to complete this task.
Declare war one time and you are done.
The loot digresses in stats from the previous part but the stats are still pretty good. You get 2 Steel Plate Jackets and 5 Chimney Sweeps.
Part 7
Pity Party
Clear 2 robbing board in any destination. You don't have to win them all, just clear them.
Go to the New York fightlist and locate the 10 Armed Guards. Each one cost 8 stamina to attack.
Go to the Hitman Tier in New York and do the job "Disrupt Rival Smuggling Ring" 16 times. The job only costs 13 energy so you will only need to spend 208 energy (even less if you get a Wheelman bonus).
Finally, collect from your Dockyard 3 times. Your Dockyard can be collected on every 8 hours.
When you are finished with all the objective, you get the Grand Prize which is a Ratite Dragster.
