So I just bought the game and purchase went through, not sure where to download the game at. lol.
you get emailed a code to use in steam - why is this such a common question xD
To be more specific click on "games" up at the top of Steam and then choose "activate a product on Steam" from the drop down menu.
After purchasing you will get an email with your Steam key. But you can always check your key at the Account Settings - History.
How and where you can activate your game key? Link: https://neocoregames.com/en/community/activating-a-product-on-steam
