i used to go out in the woods, cut down some trees, split them up into little chunks, pile em up together with some other trash i found like barrels, melons and occasional rice-patrol corpses and throw some nades into that pile. the lols were quite anti-proportional compared to the fps. also, i always enjoy thrashing buildings. its a shame there werent too much destroyable villages around.
other than that i didnt enjoy much of it. campaign sucks for the reason i alrdy stated (first time playing was ok nothing more) and shiny graphix cant make up for a lack of long term fun
