Yes, even tho it seems like you are able to save whenever you want, its always at points where it is useless to save. During the scripted events (like running through some streets filled with snipers and scum) you wont be able to save, while its really needed from time to time to save during these events. I cant count ho wmany times i had to start the whole thing over because i lost my team again and i couldnt get any further without them.

Its a shame that the AI didnt work out, because the rest is pretty good. Even tho some parts are pretty repetitive, but most games are in general.
