If Heroes & Generals fails to launch on Steam, or you are running into other issues, try refreshing the files by clearing the download cache. Here is how to do this:
- From your Steam Client, open the Settings panel by selecting “Steam > Settings” from the top left client menu.
- In the Settings panel, select the Downloads tab and you’ll find the “Clear Download Cache” button at the bottom.
- Then select “OK” to confirm and acknowledge that you’ll need to login to Steam again.
