First beat the fist level in under 1 minute 40 to access the hard levels. Next do the first hard level. Fly up and right down the hall. Bump the two or three guys out of the way and fly into the tunnel straight across the room. Get the one up and go back. Go down the tunnel straight down. Keep going towards the last green thing you have to protect. In the room right before the tunnel to last green thing is four square holes. Down one of the holes is a second free man and some sheilds and some weapon energy. Simply stay there till it says mission failed and you will be one man richer.
