Overview[]

"Unlock Standard Parts" is an option under the Add-ons menu in Sandbox mode that will immediately unlock all available parts.
It is used to buy all the parts that are unlocked normally in career mode. The price is 4€ EUR, $4.99 USD and $5.99 SGD.
This purchase does not unlock the Transponder Module and the Eagle 8 Rocket as well as the Draco Capsules and Trunk as they are not considered standard parts. They are separate purchases.
