[PC] Serious Sam: The First Encounter @ GOG (Free)

1. Create an account @ GOG
2. Click 'Go to Giveaway'
3. Scroll down to Serious Sam and click
4. Add to Library
5. Wait a couple of minutes
6. Go to your game library and either;

- download with GOG Launcher
- download the game files only

Unsure if this process is in the correct order. It's there abouts.

"GOG.com sells games that are completely DRM-free. This means that there is nothing preventing or limiting you from installing and playing the game.
As such, games from GOG never come with Steam keys."
