Hello,
As you may already know, currently after installing Eternal Return 1.0 on Steam, a [Login Failed] pop-up appears on some PCs preventing its normal access.

We have already reached out to the Steam platform team and they have confirmed that they're still working on solving the problem but that it will take some time. In the meantime, here's something you can try as a temporary solution.

■ Temporary Solution for [Login Failed]
- You can temporarily solve this issue by adjusting your Windows Defender Firewall settings.

Step 1. Run your Windows Defender Firewall
- Windows Key + R → Type firewall.cpl and press OK

Step 2. Select your Windows Defender Firewall
- Click Allow an app or feature through Windows Defender Firewall

Step 3. Change Settings for allowed apps and features
- Go through the list and find Eternal Return: Black Survival → Select "Private" and "Public" → Change Settings → Click OK
- Restart your Computer → Run Eternal Return

In addition, we are also checking on the connection failure you've been reporting to us and we will try to fix it quickly once the cause of the problem has been identified.

We apologize for the inconvenience caused.
