Taking Point

Taking Point is a Minutemen radiant quest in Fallout 4.

Detailed walkthrough
After the completion of The First Step quest and speaking with Preston Garvey, he will tell the Sole Survivor that he has discovered another location that would make a good settlement.

Once they arrive to the specified location the Sole Survivor is required to clear the potential settlement of its hostile residents (i.e. raiders, super mutants, mole rats, mirelurks, ghouls...). The second step is to use the workshop to build a Radio Recruitment Beacon and power it with a Generator.

Once those steps are accomplished, the Sole Survivor may return to Preston Garvey to complete the quest and earn some experience points as a reward.

Bugs
No or not all hostiles may spawn at the indicated location, making it impossible to complete the quest. Returning to the quest at a later moment may resolve this.
