Entrance to Koseyet Mining Camp is located at
/way mustafar 3430 157 -3130 Droid Army Heroic;
Talk to Scout Olon Lono to enter.

Once inside I like to get a rundown of the Heroic talk with Foreman Koseyet

Head West and chat with a shift leader and tell them to deploy in locations you feel they should protect namely the camp just behind them.

The majority of the battle will take place on the North Ridge of the map.

There will be droid patrols spawning on the left side of the ridge and on the right side.
It is important that these patrols do not reach the camp.

After about 20 minutes into the encounter you will Battle a GK-5 Sentry that spawns on the right side of the North Ridge.
This is the final patrol before the final battle with The Forward Commander MK1.

With the Patrols defeated lets head over to where The Forward Commander MK1 spawns on the battlefield.

The Forward Commander MK1 spawns near the North West Corner of the Battlefield.

Once all the droids are defeated head to Foreman Koseyet as he will provide the exit from the Heroic Encounter.
Be sure that all droids are defeated and you get the completion message before leaving.

100,000 Credits and 3 Mustafar Token of Heroism, can be completed once daily.
