Doom 3: BFG Edition, Playthrough, Level "Delta Labs Sector 3"

Not an overall tough level but I feel that I have missed substantial amount of secrets and unexplored areas in this level.. will have to review at a later day to see if that is/was true. Utilizing the teleporter to zip around the complex in search of inaccessible locations (hence, I feel like I have missed some). Cool level design though. Catching up on the mad scientist that opened the doorway to hell in the first place, but he teleported to Delta Labs Sector 4 - where I am now pursuing him.
