Got around to finishing this last Friday. Pretty much awesome through it all but still a hair behind the original.
They said it would be a tougher game this time around but I dont agree unless their tougher means A lot less ammo. My only gripe with the game was the ammo situation. I ran almost every chapter "on fumes", which led to more credits on ammo and less on weapons and nodes for upgrades. It did make it a tad more exciting not knowing if I had enough ammo to make it to the next store, etc. Chapter 13 and 14 with low ammo was a load/save festival :/
In the first game I loved every single level of it, in the sequel I could have done without the school area. The "onimusha" elevator and drill sequences were awesome.
Overall, well done. It'll suck waiting for the next chapter.
