Where is the bowie knife? How can you train with the barricades closed? That means you have to run up and down the stairs to get to the other side? I don't get how you can train without the barricades open.
If you are talking about co-op, its easy to train there without any problems. You don't have to use stairs you can just use yellow lighted area and area by mule kick/ Juggernog to make quick and tight circles before you start shooting.
For solo, I guess you can open the barricades and train in war room if you want. I know some people train on mule kick half of war room till high rounds with barricades closed for easy spawn. I wouldn't advice that to you unless you are very good at trains.
Bowie room is first room on left when you take the elevator down.
Im talking solo.
I am not very good at trains, I'm quite noob.
I tried opening the barricades and training but it didn't work. They all doubled back and all of them were never behind me. i circled the whole war room about 10 and still nothing. ALl the zombs spawned in. They just wouldn't go behind me.
