What Is a Steam Key?
A Steam key is a unique alphanumeric code that activates a game or software licence on your Steam account. Once redeemed, the game is permanently added to your Steam library and can be downloaded, installed, and played at any time on any PC logged into your account. Steam keys purchased on GameBoost activate on exactly the same platform as keys purchased directly from the Steam store — the only difference is the price. Each key can only be redeemed once and is permanently tied to the account it is activated on, so always make sure you are logged into the correct Steam account before redeeming.
Steam keys come in several types. Standard game keys unlock the base game only. Deluxe, Ultimate, and Game of the Year editions include the base game plus additional content such as DLC packs, season passes, cosmetic items, or soundtracks. DLC keys add content to a game you already own and require the base game to use. Always check the product page before purchasing to confirm exactly what a key includes.
Why Buy Steam Keys on GameBoost?
The Steam store charges full retail price for every game at launch and relies on seasonal sales — Summer Sale, Winter Sale, and a handful of others — to offer meaningful discounts. Those sales come a few times a year at best, and the most popular titles rarely see deep discounts even then.
GameBoost offers competitive prices on Steam game keys every day of the year, not just during sale windows. The same game that costs €60 on the Steam store at launch is often available for significantly less on GameBoost from day one, with no waiting and no compromises. Every key activates on Steam and adds the game to your library permanently, with access to all Steam features — cloud saves, achievements, Workshop mods, Steam Community, and automatic updates — exactly as if you had bought it directly.
Every purchase on GameBoost also earns 3% cashback in GB Coins that can be applied to future purchases, and 24/7 live chat support is available if anything goes wrong. With over 19,000 verified Trustpilot reviews and an Excellent rating, GameBoost is one of the most trusted Steam key marketplaces available.
If you prefer the flexibility of store credit over a specific game key, GameBoost also stocks Steam gift cards so you can add funds to your Steam wallet and spend them whenever you are ready.
