It is very, very annoying to play Guerilla on Homefront.
Being such a short campaign, it took me two days to finish. I probably died 200 times.
Your allies to nothing, and it seems like all the enemies ALWAYS shoot for you. It's hard to advance forward in to complete an objective, and ammo is scarce.
But the good thing is, there are no repawnable enemies. So, eventually they will all be cleared out. It takes some patience and time, but the 175G is so worth it....
