In that mission you had to follow a train that was occupied by a load of rival gang members while a fat bastard called Big Smoke sat on the back of a tiny dirt bike, constantly falling off like the big fat eejit that his is.
Basically, you have to weave in and out of objects following the train whilst keeping Smoke on the back of the motorbike, so he can go about the business of capping members of the rival gang. Sounds easy, right?
Wrong. It was really tough.
Too tough, really. That's why people just run about killing people and doing the weapons cheat.
Worse is the fact that every time you fail, Big Smoke says: "All you had to do was follow the damn train, CJ!"
It gets annoying, trust.
Anyway, as a little in-joke for fans of GTA, the folks behind RDR2 have built in a little mission where you have to - you've guessed it - follow a bloody train.
The difference on this occasion is that you're not on a motorbike, and there is no one on the back making wisecracks that seem unrealistic for someone in obvious mortal peril,
You're on horseback, which should in theory make it more difficult to chase a train, but it's the turn of the 20th century - back then trains weren't quite what they are now.
"All you have to do is follow the damn train, Arthur".
