Xigncode3’s process bar stopped at about 20% when starting the game on Steam.
But I’ve fixed the problem after validating the integrity of the game chache:
1. kill the game’s process, if it is stuck (task manager -> kill “ShooterGame-Win32-Shipping.exe”)
2. Steam -> library -> games -> right click dirty bomb -> properties -> local files -> verify integrity of game chache
It detected that a single file was not as it should, so it added it to the downloader. I had to pause and restart the downloader to make it actually start the file transfer.
After the download and starting the game, Xigncode3 ran fine and the game initialized properly.
The file in question had a size of 511.1 kb.
I hope this helps other players experiencing the same problem.
