Hitman supports multiple approaches, giving players the choice of how to tackle their objectives.
Hitman traditionally gives players the freedom to do as they please in terms of infiltration and assassination, providing numerous opportunities to take the flow of events in a whole ner direction.
To help demonstrate this, IO Interactive showed off a new walkthrough of the Showstopper mission at EGX. It starts at 8:56 in the embedded video below. If you like, you can compare this to the Showstopper playthrough released at PAX 2015.
This new Hitman is a bit different from past entries; IO Interactive wants to keep adding content to it, kind of episodically, after launch. However, in order to pack more content into the initial release the team has decided to push release back to March 2016.
