Let's play DOS Games - Duke Nukem 2 Episode 2 (Part 3)

I'm already halfway there to beatepisode 2 in Duke Nukem 2. Somehow I felt in level 6, that I couldn't fin the force field to get disabled since I found the access card for it and also I was in critical situation in level 5, when I found the key to open a door and advance to the next level. I luckily managed to complete level 5 and advance to the next level and now I ended up on level 7.
