ok so with the battle with wesker me and this other guy immediately pushed over the boulder and both got together before wesker even halfway made it back down the walk way, apparantly this skipped a cutscene where chris helps sheva across and one where wesker raises his huge arm to show his weakness when you both stand on the flat lil hill.  did this happen to anyone else?

Yeah of course that's a part of the game and lets you to shoot him accurately.

what i am saying is that me and my partner seemed to skip both of those cutscenes some how, and i dont mean we just hit the back button. they never happened, the dialogue happened during the chasing, but instead of doing his next move set, he became invulnerable and continued to twirl his arm around while chasing us, we later had to go back and fight him slowly allowing him to fight chris while sheva ran then pushing the boulder during the chase, instead of pushing it while he was chasing chris.  I wonder if anyone else had this strange problem

wow.  That was ridiculously incoherent.

English speaking denizens should learn written English before they attempt to use it.
