In TranZit, complete all additions to the bus in 1 game.
There are four total locations that the parts can be. The video below shows only three. All four locations are below. Bus Depot
From the starting room build the fan and open the white door that says you need power. The part will be to your right. Diner
From where you get off the bus, go left to the shack. Use the fan and there should be a piece in that room. Farm
First open the gate for 750 points. Then continue forward and there will be a door you need to use the fan on straight in front of you. Piece will be on the floor. Town
When you get off the bus you head to the left and down the street. Weave through the cars and there will be a door on the right. Once again use the fan on the door and the piece will be inside.
I believe this is three separate parts: the plow (looks like a train grill) that you attach to the front, a ladder that you attach to one side, and a hatch that you attach from the inside of the bus. You need to find these and attach them all to the bus to get this Achievement.
Yes I now know they spawn at different locations. I just got this and happy hour (I think that's what its called) in the same game on solo by round three. I was trying to get the other and I just got lucky that the three parts were at the first three stops.
this one is easy did it all with round one. what you do is keep one zombie alive in round one and just go around the map till u got all 3 parts. remember to keep rebuilding the windows while u on the boss because he will try to break in. just keep running around him. you wont have to do no fighting if u keep tht last zombie alive in round 1
@9 thanks bro the ladder was where the what ever its called thing you put in the front of a train piece they were basically switched other than that it went just as u said,cool stuff thank you very much
