oh, on hourglass once. We had taken out the AGT with a flame rush, one guy was shouting FLAME RUSH THEM over and over, yet it never worked cause they had like 5 mammies. I actually found that steaths are rather decent in this situation. There were like 4 at the time I was rushing alone, 2 on the left side of the AGT, one behind it and on to the right. Well, I didn't see any way to get into it until I saw the harvestor, it got in the way of the one on the right and push it back, which gave me my way to get in. only thing I had to worry about was a lone havok that was infront of the harvestor, I just ran that fool over and proceeded in, I was caught though. if I was a stealth soldier I would have done better because I tried to enter a mined building as tech and sadly, didn't make it.
