Hitman: Blood Money

“Hitman’s back, drawing you closer than ever into his deadly world where staying anonymous, being smart and totally ruthless are the key to a perfect execution. Lucrative contracts on the rich and powerful in high profile locations make killing for money good business.

“But when a rival agency enters the scene it’s war and only the best man will be left standing.”
