If you own Hitman 3, then there is now another reason to take a look: Not only do you get the missions from Hitman 1 and Hitman 2 for free, but also the new Freelancer mode, which is inspired by Roguelite games.
The Freelancer mode places much more emphasis on the sandbox aspect of the series. Here you have to find your own targets and take them out. In addition, there are bonus objectives for which you have to find out for yourself whether you can fulfil them at all. Because that’s not necessarily possible.
If you don’t have any of the new Hitman games yet, the purchase process is now much easier: There is only the World of Assassination Bundle, which gives you the content of all three parts.
