No Sun to Worship (Mission 4: Nuclear Plant)

If you've ever wondered what the inside of the Matrix may look like, this level should give you a good idea. The further you get into this game, the more you wonder about your life choices. Should I pop heads like melons? should I shank them like a prison movie? is stealth really worth it instead of mowing down the guards and doing a speedrun of the level? I ponder these things.
