i cant seem to get to the location of the memory start icon. its still behind a block off part of Rome and i have no idea how to unlock it. can anyone help?

" What was the last thing you did? "

" Right, so the icon should be different, it's an L icon or something. You need to go over and kill some guy to start the Leonardo's machines mission. "

i figured it out. apparently you have to run around it.

@Shirogane : I am also stuck with the same problem as Jackel was ..... and i tried goig to bottom right side as you said .. but all i find is a closed GATE ..... PLEASEEEEEEE HELPPP anyone..i am stuck after memory 8 of sequence 4 ... completed all the missions in the available area theres none left now :(

@ashu4msjs: Eh.....it's been like over a year since i played this game, so i can't really remember. But you need to find a way to get to the L icon on your map. It'll look like the area is blocked off, but there is a way around somewhere, you just have to look for it, can't be much more specific since i havn't played the game in a long time, maybe look up a guide somwhere?
