[spoiler]i went onto a building but OK[/spoiler] [b]I walk over, plant one explosive charge, walk over to the corner of the room, and then realize if pull the trigger that the cars will explode and i will kill myself. I look for another way out. I decide to plant the charge on the OTHER side of the wall and have it blow into an alleyway. I walk over to the left wall, (assuming i'm facing the entrance)place the charge, and back up to where the cars are. I pull the trigger and the walls detonate i run out into the alley, and wall-jump up onto the rooftops, where i empty a clip of my Skyranger at the Psions in the street.[/b]
