You own the product, NOT the Software intellectual property, also known as software IP, which is a computer code or program that is protected by law against copying, theft, or other use that is not permitted by the owner. Software IP belongs to the company that either created or purchased the rights to that code or software. If they do not want you to be able to make changes to the mission(s) they reserve the right by law to block any chance of editing it. You would have to buy the SIP or buy into the company at a level that would give you the right the edit the code. Pretty simple really. You could go through and change just enough to call it your own and market their hard work as your own. Not saying that you, yourself would but there are people out there that do.... all the time.
