After a few more (accidental, in one case) hostage “missions”, I set about doing the next two Westside Rollerz missions.
The first was a race, of sorts. I didn’t have to win, however – I just needed to get close to the Rollerz and taunt them enough to make them use a nitro boost. Which was rigged to make them explode, of course. Obviously.
Then I had to attack some garage owned by Donnie, and Lin (a Saint, but undercover) “saved” him at the last minute. After all that, I drove around a bit and blew things up. I also had a pushback to resolve, which was pretty easy.
