Congrats on being invited to the HYENAS Alpha!
In your welcome email you should find bucket loads of information, but you really just want to get the game installed and start playing right?
Fortunately, this part is easy:
1. Find your HYENAS Alpha key in your email.
a. Check your junk/spam folders for an email from firstname.lastname@example.org
b. If you still don’t see an email from us, please submit a support request.
2. Once you have your key simply head to Steam and select ‘Add a game’ in the bottom left corner.
3. Then select ‘Activate a Product on Steam.’
4. Continue through the proceeding agreements and choose your installation directory.
5. Install! The game should be around 31gb.
