A level in Hitman: Absolution was changed due to the negative reaction from fans that saw a gameplay trailer.
A teaser video was released showing Agent 47 assassinating a group of nuns without any stealth gameplay.
Hitman: Absolution director, Tore Blystad, told Eurogamer: "The Saints trailer is based on a level within the game. One way to go about that level is to go in all-guns blazing, but of course, that's not the smartest way.
"We learned from the trailer that we really needed to give these characters some context and some backstory. We're working within the game - within that level - to build these characters up before you meet them. That way you know what you're getting and you aren't put off by them."
Blystad claimed that nobody knew how badly the public would react to the trailer.
He added: "We were surprised by the reaction to it. We've been trying to find out, you know, how could we not see this happening? If we knew it would get such a negative reaction we would have done it in a different way."
