The Division 2: How to Get the Underboss Exotic SMG

The Underboss is the Exotic submachine gun tied to Year 8 Season 2 “Into the Dark” in The Division 2. It is a Tommy Gun variant carrying the Gangland Hit talent, and it drops only from the season’s Zodiac Climax mission set inside the Tens Nightclub.

Quick answer: Complete all three Scout HVT activities to unlock the Zodiac Climax mission, clear it once on any difficulty, then finish it on Master. Your first Master clear has a 100% Underboss drop chance.

Underboss Exotic SMG stats and the Gangland Hit talent

The Underboss is built for co-op. Its talent marks enemies and amplifies damage against those marks, and the effect scales up when several agents run the same weapon on one target. That makes it strongest against heavy units and named bosses that soak damage.

Detail	Value
Weapon type	Exotic SMG (Tommy Gun variant)
Optics slot	+15% Critical Hit Chance
Talent	Gangland Hit
Mark on hit	One mark at a time; transfers to the next enemy you shoot
Mark stacking	Up to 4 marks per enemy across agents using this weapon
Damage bonus	+20% Amplified Damage to a marked enemy, +5% for each extra mark beyond your own

Solo, the weapon lands a flat +20% Amplified Damage on the enemy you have marked. In a squad running Underboss on the same target, the extra marks push that multiplier higher, which is where the gun does its real work.

Unlock the Zodiac Climax mission first

The Climax mission is not open by default. It appears only after you finish the seasonal Scout HVT activities and uncover the primary manhunt target. Three specific Scout objectives gate access.

Into The Dark Week 1 Manhunt HVT (Scout 1)
Into The Dark Week 5 Manhunt HVT (Scout 5)
Into The Dark Week 9 Manhunt HVT (Scout 9)

Once those are solved, the Zodiac Climax mission unlocks in the Manhunt menu. You can fast travel to it from there. Note that Zodiac reworks the Tens Nightclub from the Classified mission of the same name, rather than reusing a raid map like earlier seasons.

How the Underboss drop works

Drop chance scales with difficulty. Lower difficulties only give a random chance at the weapon, while the first Master clear is guaranteed. There is a gate on Master, though. You must complete the Climax mission at least once on a lower difficulty before the Master version becomes available.

Difficulty	Underboss drop
Lower difficulties	Random chance, improving as difficulty rises
Master (first clear)	100% guaranteed drop

Requirements to attempt the Master run are a level 40 agent and unlocked access to the Master Climax mission. If you own the weapon already, you can reconfigure its third attribute later. The Underboss can also be traded, but only with players who were in your party when it dropped.

Note: Targeted loot does not help here. The Underboss does not come from open-world activities, Countdown, or Exotic caches, and no in-game vendor sells it.

Tens Nightclub: Zodiac Climax mission route

The mission runs through the nightclub’s themed lounges under a Toxic status pulled from the PvE Dark Zone. Keep a healer nearby, ideally one built around Birdie’s Quick Fix backpack, and expect constant flanking pressure. The stages below run in order.

Clear the Brass Bar. Waves push in from the far stage, the near bar, and the balcony above. Wipe them out, inspect the dead body, then open the door toward the holding cells.

Reach the lower holding cell and the Platinum Lounge. Move to the far end and speak to the civilian, which spawns a wave along with the Underboss-named enemy. Kill them inside the timer to open the next marked doorway.

Take the lift up into the Gold Lounge. A heavy and a rusher spawn close together as you enter. Down both, then interact with the keys at the control panel.

Drop back down to the Platinum Lounge for a large horde fight while the Toxic status is active. Lean on healers to counter the sustained damage and the heavies flanking your position.

Push into the Silver Lounge and defend against enemies guarding three Spice containers. Heavies arrive from the far end while rushers hit near your entry. Clear the room, shoot the containers to destroy them, then head back and climb the steps on the right.

In the upper holding cells, plant thermite charges on four generators while endless heavies, rushers, and captains pour in. The constant Hyena spawns make this drawn out, so use the pillars for cover and stay close to teammates.

Enter the VIP Lounge carefully. A spawn door opens behind you the moment you step inside, so watch your positioning and keep the healer up to avoid getting pinched.

Fight Zodiac at the Disco. This final arena floods the upper entry floor with Toxic fumes, so drop down and set up behind the bar, ready to reposition. There is no confirmed fixed safe spot, so keep moving alongside a healer through the encounter.

Confirming the drop and dealing with a hard run

You know the unlock worked once you clear Zodiac and the Underboss appears in your rewards after the mission ends. On a first Master completion, the drop is automatic, so if it does not show, confirm you actually finished on Master rather than a lower tier you still had access to.

If the mission is too much to solo, call in Shepherding agents or matchmake with friends, and bring a Legendary or Master-tier build to raise your survivability through the Toxic waves.
