Proving Ground (LWOTC)

Back to the main page

"The Proving Ground facility provides space for Shen to experiment with new types of weaponry and other unconventional equipment. Using this facility, she can produce ammunition, explosive ordnance, and armor for our troops."

Long War of the Chosen makes a lot of equipment items first be researched in the Proving Ground before you can build them in Engineering.

• Unlocked items in bold don't need any other project, while items in italics need another research or Proving Grounds project to be fully available.
• Projects with a yellow background form part of the Golden Path: the elements that progress the storyline.
• Every project that unlocks an item will also grant that item on completion.

Project Time

The time to complete a project is based on a points system: each project has a required amount of points to complete, and each hour a number of points is added depending on the Proving Ground's staff. The Proving Ground has two slots for engineers that reduce project time by 50% each.
