- Creator's Favorite Episode: David Bateson (the voice of 47) considers Silent Assassin to be his favorite game in the series.
- Dummied Out:
- The rosary beads in the ending were originally planned to be a substitute for the fiber wire throughout the game. It must have been cut late, as there's still a spot for it on the gun wall.
- Early released versions
- The posters in the India levels were based more on realistic religious themes in some early releases and were changed to more generic ones to avoid offending people.
- Terminal Hospitality is based on a real life sikh holy site, and had an altar with weapons on it. Unfortunate Implications likely changed this.
- Agent Smith originally referred the citizens as Towelheads; take a wild guess why it was removed.
- Back in the Gontranno church, 47's weapon display has two spots that are never filled. From the outlines behind them, they seem to be the fiber wire and 47's rosary; both of which he has on him at all times. Also, if you use the 'all weapons' cheat, a cigarette lighter appears in your inventory.
- Follow the Leader: By the end of the Japan assignment, you will have trekked through mountainous tundra, dodged snipers and dozens of anachronistic sci-fi ninjas, defeated the best laser security system money could buy, and infiltrated a massive fortress. The perk here, at least, is that you get to blow up a helicopter.
- This is also the only Hitman where you can stow away in the back of trucks carrying boxes.
