open source fps game developed with Unreal Engine (I am currently using the version 4.18 source build, only blueprints)
anyone who wants to improve the project is well accepted.

(StarterContent)
The repository lacks the "StarterContent" folder in the / Content / StarterContent path

You should add this way to the editor:
Go to "Add new" in the content browser - "Add feature or content pack" - choose the starter content

(ArbitraryStudio)
The repos also lacks a free template folder, downloadable here:
https://gumroad.com/l/uPXbQ
(to add in the "content" folder of the project)

(InfinityBladeEffects)
downloadable from the marketplace

To do some tests use the .bat files:

• "startMainServer.bat" start the main server.
  
• "startServerMap1.bat" start the map (only 1 map at moment)
  
• "startClient.bat" start the client
  
• "StartDefaultTest-2Players.bat" start two servers and two players.
  (to make these batch files work you have to update the bat files with the correct path of your Unreal Engine installation then it will works)
