The Black mesa research facility we have scientists and we track down some bad people and we can use them as our test subjects some of them may to too risky that we might not even get them any risks above 6 or above will be impossible for us to get them We have a risk level so risk level 1 is the good and risk level 10 is the baddest a risk level 10 means that they cannot be captured and it is impossible to do so we also have a magnitude system to scale our accidents The limit of it is 20
