Hi, for the "mechanic mission" (after you returned from the bridge mission) you can use the same train to get to the level, then you have to complete the map.
It's the tank in the corner, right? But I can't remember how to get there again. I think I got there in the previous version of the game, but I don't remember how to do it again. I guess I'll try again. By the way, is it normal that when you leave that cryo-tank room, those stairs don't work? I tried to go up them, but they don't work, and I see there are chests and infected on the other side. An infected jumped over the fence and tried to attack me. There's a wall in Command Bridge that you can explode, and it's barely noticeable at first glance, but when I went inside, I saw that it's a ventilation shaft. There are some green stairs that don't work; there's nothing to do in that little ventilation shaft.
Hi, the train is outside the medic bay, on the top left of the map.
The green stairs inside the ventilation system were bugged, but I’ve fixed them now.
The mechanic is past the stairs on the right side of the cryotank room. There was a problem with the map that prevented you from passing, but I’ve fixed that as well :)
Thank you for reporting these issues: it really helps me!
