Star Wars: Chewbacca (2015) #2

Zarro and Chewbacca are scouting out the entrances to Jaum's dedlanite mine.  Afterwards, Zarro allows herself to be captured while Chewbacca reluctantly descends into the mines through an air vent.  In the mine, Zarro is reunited with her father Arrax, but Jaum tells Arrax he sold the mine including the indentured workers.  One of the workers is upset and raises a shovel and Jaum kills him, causing a panic among the remaining workers.  Zarro and Arrax run, but are cornered by Jaum's men.  Chewbacca appears and rips the men apart with his bare hands.  When he fires his bowcaster, Zarro warns him the dedlanite is explosive.

Chewbacca rigs a power droid as a weapon and when a guard droid shows up, Chewbacca stops it with his rigged contraption.  Meanwhile, Jaum is informed of Chewie's presence and Jaum kills the messenger.  Chewie finishes off another guard droid and hits one of Jaum's men with the power droid.  He takes his bowcaster and leads Zarro and her father through the mines.  He emerges from a tunnel on a loading dock with carts full of dedlanite.  One of Jaum's sharpshooters hits a cart, causing a powerful explosion.

Zarro and Chewbacca are both shown on the cover for Star Wars: Chewbacca #2 by Phil Noto.  Surprisingly, this issue only has the single cover.  This is a rare occurfence in the modern era.

Star Wars: Chewbacca #2a - Marvel Comics, U.S. (October 2015)

So far, this story is very forgettable.  The standout moment of this issue is when Chewbacca enters the air vent and has flashbacks to being captured along with other Wookiees by Trandoshan slavers.  He quickly clambers out of the air vent to summon his courage before climb back down into the hole.
