Buy Kerbal Space Program: Making History Steam Key

Q: Why is the Steam Key of Kerbal Space Program: Making History safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Kerbal Space Program: Making History to your game library. The account format requires more complicated steps and is more prone to errors during activation.

Is it worth buying the Steam Key for Kerbal Space Program: Making History now or waiting?

That €2.66 key is at one of its best prices.

Those €2.66 are 27% below what it usually costs, measured on the store price.
16 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
Not counting today, only 249 days out of the 2,290 days on record were this cheap or cheaper; the lowest it has ever cost is €2.00.

At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 4,252 daily records of the Steam Key for Kerbal Space Program: Making History across 35 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Which Kerbal Space Program: Making History format should you buy?

By format: Steam Key from €2.66 and Steam Gift from €15.65.

Can you activate Kerbal Space Program: Making History in US?

18 of the 22 offers work on US — the Global ones plus the ones issued for your own region.

Why is there such an expensive Kerbal Space Program: Making History offer?

One listing is worth ignoring: the Steam gift that G2A has at €16.60 is more than 6 times the cheapest offer and is not what this game costs. The number to work from is €2.66 at HRKGame.

Kerbal Space Program: Making History will allow us to expand our Kerbal experience in an unimaginable way. This is the first expansion pack for the acclaimed simulation and spatial construction game, and adds a lot of content to the original game including the Mission Builder pack, a story pack with missions inspired by historical events, and lots of new parts so we can mount anything we imagine and throw it into deep space.

The most important addition, without a doubt, is the Mission Builder package, which will give us the necessary tools to create an unimaginable number of missions with endless possibilities. Players can customize their own missions to include launches, landings, rescues, breakdowns, explosions, repairs and more. We will be able to establish the conditions of victory, challenges and unexpected obstacles, and most importantly, we will be able to share them with the community for infinite hours of play.

And if we don't want to create new missions, then we have the story pack with which many more pre-fabricated missions inspired by humanity's own space exploration will be available.

This product is a DLC so you need to have the original game installed in order to access all the new content of this product.
