THE GEP GUN IS THE MOST SILENT WAY TO ELIMINATE MANDERLY.
So, serious talk. The first Deus Ex game I played and finished was Human Revolution on the X360; I then finished it on PC as well. I tried Deus Ex 1 about 6 times, and every time I would get frustrated because I couldn't even get onto the statue, and I always was expecting auto-save to kick in (which is really silly of me).
A few days ago I was watching TotalBiscuit's retrospective of Deus Ex 1, and I saw a whole new way to play the game. I'm right now in Hell's Kitchen for the 3rd time, just because you send the radio transmission. loving loving this and can't believe I never did this before.
