i'm just a bit curious cause i've seen the same on a few forums and the load times on some consoles (cough cough xbox) are a bit... lengthy

No idea how it would work though, like all 9 collectibles would be obvious, but what about guests? Would you need to get both? Would you also need to get them to level 4? If so would doing it in the level you were running be mandatory or would any level be fine? I think its pretty funny to think about lol
