Dude, no joke! AKUMU is beyond Dark Souls levels of bullshit (and I love Dark Souls, but). I'm halfway through chapter 7 now, but it took me about three hours just to get through chapter 6. They littered the boss arena for the Sentinel with bear traps, and I died WAY more to them than the actual boss. I wish it was more like a Heaven or Hell mode from Devil May Cry 3, where even though you die in one hit, so does every single enemy.
I'm trying to get platinum right now, so once I'm done with AKUMU I'm going to try to do a no upgrades speed run through casual. After that it's just a matter of cleaning up every other miscellaneous trophy. I might go through and do a no reticle run during my cleanup. It'll definitely give a fresh experience to it all, since I've played through on regular old survival mode like 10 times already.
