Baal plays Resident Evil 5

if it takes a while it might not be a good idea to do that, jill will beat the crap out of the a.i in no time unless you have the a.i constantly follow you by calling them, but if you do that you run the risk of jill attacking you too

Oh, it doesn't take long at all. It just involves leading his ass up the stairs and blasting him in the back three times until he turns towards you. ...Of course since you'll be behind him on the second level while he's still climbing the stairs he'll just be dashing towards the railing before turning around and trying to go up the stairs again. Of course, you'll have to initiate Wesker kicking you through a door first so Jill doesn't murder your ass while you're trying it.

Rinse, Repeat and done. I beat him in like under a minute with this strategy and it's how I got the Heart of Africa.

i never tried that before, you probably won't have a problem then if it doesn't take long
