I played this map on my server with 5 people, I was satisfied because everybody liked the performance of the train vehicle.
Watch out as this train carries enemies on it, and watch out for this train it goes back and forth (laughs) it was very cool, watch out for the sniper.
There are objects inside the Submarines and inside the ship as well.
So if you do not complete some subgoal. it is because he got objects without destroying inside these vehicles.
