I would say that Hitman blood money holds up still to this day. There's a reason why Hitman and Hitman 2, that have come out in recent years, are designed the way that they are. It is because of the success of this game and what it did with gameplay.
The other room is an easter egg. There's a room in the basement full of garbage bags. Rats can be seen on the floor. Kill 3of them and you'll get the keycard over the table.
I have played every single hitman and it is fucking depressing that the one from 2008 that costs less than a dollar is by leaps and bounds superior to the new trilogy that charges 200$+ of content and its buggier too!!!! also do you have to pay to get your map looking like that? All that is marked on my steam copy is me, the target, vips, optional targets, and the exit, I dont even have anything that could be the blue icons
