in AC2 Brotherhood there were these restrictions you had to pass for each story chapter which would award you 100% completion. So at the beginning of a story chapter the game would tell you: don’t ride a horse! And if you did everything right but rode a horse you wouldn’t get the chapter marked as completely complete.
There is one chapter where they tell you: DO NOT SWIM! But the chapter starts in the fields outside Rome. No water there. The first 15-20 minutes involve the player pretending to be in a stage play. No water in the theater, so no swimming. At the end of the stage play, you talk to one of the actors, but he’s suddenly poisoned by an attacker and the game tells you to run him to a healer. So you start thinking: AHA! This is where I avoid WATER! But there is only a little stream nearby, and you can cross it on a bridge You start thinking: heh! This is an easy challenge!
But while you are talking to the healer, A NEW GUY runs by out of NOWHERE and you realize that you recognized him from an earlier scene where he burned down your home or some shit. Chasing him down, there’s no water at all. But when you catch him, he tells you that your bro Nicolo Macchiavelli is back at your hideout and YET ANOTHER GUY is about to assassinate him, in something like five minutes. So now you have to run all the way across the open world map of Rome in an amount of time that feels fucking impossible. Five minutes!!! What the hell!
But you love Macchiavelli so you start running. I personally got so invested in saving Macciavelli I totally forgot about the water. And then finally at the last moment I had like 10 seconds left to save my bro and realized that my assassin hideout was on an island… in the middle of the Tiber river… and the only way to get across it without swimming was to take the long ass way to a bridge. So I dove right into the water.
It’s a great episode in the story but it’s also the sneakiest most fuck-you tricky shit in the game, IMO. They emotionally blackmailed me into jumping into the river. To this day that’s the only part of AC I remember or care about. And if you want to replay that chapter to complete it in time, you gotta do like 30 minutes of stage play stuff first, and probably also practice runs back and forth across the whole fucking game map over and over until you figure out how to get to the bridge with enough time left over to save your bro. And every time you fail, your biggest NPC friend just dies. Maximum spiteful, but I loved it.
