AusGamers goes hands-on with Battlefield: Hardline's multiplayer ahead of the open beta and writes:
To increase the emphasis on the vehicles, Visceral gave us access to the newest mode they're showcasing -- Hotwire. Hotwire is basically Conquest except here all the capture points are vehicles. What this means is that you and your team members need to find the target vehicles, get in them and drive them as fast as possible. The point isn't capture if you aren't driving over a certain speed, so it reads on paper like some sort of insane Speed twist, but in practice it turns every battlefield into a crazy Mad Max style arena of chaos.
