A forum exists about this already, but it was a great idea so i decided to start another, but with the balancing addition of C4. A train that ran along the existing train tracks would be great. It would start broken, and could be fixed with existing vehicle parts. This could act as a mobile base for players, while adding something to fight over. C4 could be placed along the tracks, and detonated to damage the train.The C4 would have to be crafted from 2 or 3 parts as well, so that not everyone could have it on them. It would have to be fairly visible so that it isn't a surefire train explosion. If it was visible, the train could have a lookout, and they would have to call out to stop the train, and shoot the C4 to detonate it so that they can move on. This would lead to a train battle, where people try to take or defend the train. Any suggestions or ideas would be great, and i hope the game dev's can add this sometime in the future. :D
