General advice: Equip everything that gives you a higher gear score for the following section until you're at around 490 score.
Congratulations, you have reached level 30 and kicked the True Sons out of the Capitol. However, that means that a new faction, the Black Tusk, starts invading Washington DC. Their advanced tech calls for some more serious firepower and that means that the quartermaster will call you back to base. You'll get the option to pick a specialization. Doing so unlocks an achievement:
Unlocked by 27,789 tracked gamers (48% - TA Ratio = 1.43)
The next achievement requires you to kill an enemy with each signature weapon (TAC-50, Crossbow, M32 Grenade Launcher.) You may need to kill some enemies the normal way before you have signature ammo. Start with the TAC-50 and when you have a signature round, bury that in an enemy's head for the first step in this achievement. Then switch to the Demolitionist in the base and kill an enemy with that signature weapon. Finally, swap to Survivalist and kill an enemy by shooting him in the leg. Red bar enemies are the safest option for this. When you've killed an enemy with all these signature weapons, an achievement will unlock for you:
Unlocked by 10,768 tracked gamers (19% - TA Ratio = 2.30)
Keep Survivalist active and shoot 9 more enemies in the leg with the crossbow for a familiar-sounding achievement:
Unlocked by 5,359 tracked gamers (9% - TA Ratio = 3.27)
Now it's best advised to pick the specialization tree you want and start working through the world tiers. In order for the most efficient progress on the next achievement, you need to only get the level 1 upgrade of a perk in the spec tree if the perk has multiple levels. For weapon type damage perks, max out the node that has an attachment locked behind it. In total, you need to get 85 points in the specialization of your choice. When you've invested the spec points as outlined above, you'll get an achievement for your troubles:
Unlocked by 12,388 tracked gamers (21% - TA Ratio = 2.15)
You can respec your points for free at any time to get the perks you actually want to use.
During this whole process, you are likely to have obtained high-end (yellow) gear for all your gear slots, unlocking another achievement:
Unlocked by 26,787 tracked gamers (46% - TA Ratio = 1.46)
When you've worked your way through all invaded missions and are in World Tier 4, a new one will open up: Gatehouse Facility. Complete this mission and get a Gear Score of at least 425 to start the true last stronghold, Tidal Basin. The final area of Tidal Basin has you disable various rocket launchers while fending off a lot of enemies and the mission boss. Stopping the rocket attack and clearing out all enemies allows you to collect the objective materials and finish up this mission, leading to World Tier 5.
Now here's where the game really changes. Invasions happen weekly and are on a rotation and control points have alert levels. Getting them to at least alert level 3 will allow you to earn a random blueprint from them, drastically increasing the pace at which you collect blueprints.
For the next two achievements, start playing all the main story missions on Hard difficulty, it doesn't matter if they are invaded or not. Focus on getting headshots throughout the missions to obtain Combat Merit commendations/patches. Once you have ten patches, you unlock an achievement:
Unlocked by 20,043 tracked gamers (35% - TA Ratio = 1.69)
Keep working through the missions on hard and when you complete your final one (which will likely be Tidal Basin), you unlock the difficulty-specific achievement in this game:
Unlocked by 5,730 tracked gamers (10% - TA Ratio = 3.16)
Finally, we're going to hunt for a craftable exotic. The Chatterbox SMG is the easiest of the four currently available to obtain since the Liberty pistol requires an RNG high-end weapon drop, the Dodge City Gunslinger Holster has a fairly long project and two RNG drops needed and the Nemesis marksman rifle is time-gated. You need to find three parts of the weapon in Hyena crates, which are boxes you can only open with Hyena keys. These boxes have a 24-hour cooldown before they can be re-opened. This also has to be done in the following regions:
- Downtown East
- Federal Triangle
- Judiciary Square
For the Downtown East area, there are two of these boxes in the normal version of the Grand Washington Hotel mission. One of them is after the first atrium fight in a bathroom to the left of the hallway and the other is when you arrive on the roof, to the right of the stairwell before clambering over to the other side.
The Jefferson Trade Center mission has one box in it. This box is after the parking garage fight in the back right corner of the room the objective points you to. If you have no luck there, run north from the Navy Plaza control point and go left in the first alleyway. Climb all the way up and to the left to find a Hyena box.
For the Judiciary Square mission, do the Police Headquarters side mission and look at the far end of the parking garage you complete this side mission in to find the box.
When you have all three of these parts, it's time to do the normal Bank HQ mission. Remember that keycard panel I pointed out right after Rebound? Open it (stand near the right side of it and hold ) and take the keycard. Inside the bank vault, open the left door to find a Hyena box. Use a key on it and you'll get the "Lost Chatterbox" blueprint. You don't have to complete the mission and if you have the requisite resources you can craft it, earning you this achievement:
Unlocked by 10,832 tracked gamers (19% - TA Ratio = 2.30)
Now, it's mainly a case of getting a decent build together for the Operation Dark Hours raid.
