I feel like I missed a whole other game before this one, is there like a prequel or something? this characters talk like they already knew, Im so lost, please help lol

game looks really good but I am afraid its going to be a cakewalk like the gunvolt series. Does this game actually have challenging enemies and bosses? Especially in co-op mode?

I'm a big Castlevania fan (both classic and IGA style), so I should be the exact target audience for this, but good lord in heaven, this game will be impossible to play in front of other people. And I wouldn't even want to play it alone cause those voices are so high pitched they're like nails on a blackboard....

As per the title, up, left, right, down working no issue but diagonal commands that requires up and left or right together when pressed not working and that is on pad or r stick, any help would be appreciated.

After going back and forth for more than 12 hrs today, I finally got the "alternate" ending. I assumed I'd get the panties achievement along with it, but apparently not. I have a few things I haven't tried yet, so I'll maybe do that tomorrow. Specifically: I'm thinking the two sisters still don't have their underwear so maybe I'll see if I can finisher shot the 2 bosses I haven't done it to. , but I have low hopes....
