Mass Effect 2 - Exploration of Unused Gang War N7 level

I was looking in the files of ME2 and noticed there was this level file that didn't appear in any other version of the game. The level seems to have been shipped accidentally because the level is incomplete and would never be seen by regular users. The level is called "N7GngWr" and presumably was going to be a level where mercs had fought over something. The level isn't referenced anywhere else in the games including the plot database so all details are relatively unknown.
