Hitman 2 is the sequal to the 2016 game Hitman and follows on from the events of that game as Agent 47, a contract assassin embarks on a mission to hunt the mysterious 'Shadow Client' and disassemble his militia.
The game features six missions, which are set in six different locations;
The missions each have a bit of backstory baked into them, that can be picked up through conversations with the subject or through intel you pick up along the way which helps to flesh out each mark. When you complete a mission your portfolio of killing instruments will expand and will include sniper rifles you can smuggle in briefcases to remotely detonated mines that you can leave in a suitcase for unspecting guards to discover.
Hitman 2 also has a cooperative multiplayer mode titled Sniper Assassin which set in Himmelstein, Austria. The official trailer of which is below.
