It shouldn’t take too long, depending on your internet services, as the test server itself is only about thirteen gigabytes in size, so downloading it should be a cinch.

Once you find it, go ahead and give it a download. It should look like the text in the screenshot below. It’s located directly under PUBG’s normal mode in your library list, and it should be called PlayerUnknown’s Battlegrounds (Test Server). In fact, all you’ll need to do is own PlayerUnknown’s Battlegrounds, and then look for the item inside of your Steam library. Getting into the test server is extremely easy, and it won’t take much to pull off.
