Steam is a digital distribution platform for video games and software. It allows users to purchase games and software from the Steam store, and then play them on their personal computer. Steam also provides a service that allows users to connect with other users who have installed the same game on their computers, and share achievements, tips, or reviews. To get a Steam Access Code, you first need to create an account on Steam. Once you have an account, you can find the link to get your code in the upper-left corner of your screen when you start Steam. After getting your code, you can use it to activate your account on Steam.
