chapter 13 boss not dying?

Had the game on the lowest graphic settings, lowest resolution, vsync off, restarted the chapter twice! and uninstalled and reinstalled the game and still it doesnt work!!

hmmm turning everything down to lowest settings and vsync takin off did work for me...... but im still wondering why

Did not work for me same glitch no go!!! Please lets have a patch 10- hours trying!!!

HELP HELP! But there is another bug in Chapter 13 are the boss and midice to press F quickly and pop but I know that should go on the camera but instead makes me back and forth and I can not find that you can overcome please what I want so much to overcome

Still dont work.

FINALLY FOUND SOULUTION!!!!! I had the same problem as everyone else, boss would bug out of harpoons wouldn't die and crap (litteraly tried for 1 hour once -_-). but the low settings thing actually worked. change visuals setting to low, turn off v-sync, windowed (full screen), and resolution to 1024x768 60hz. rapidly pressing f for some reason has the opposite effect, so i recommend using your less dominant hand for button mashing.

This also worked for me with one tiny addition:

Mash the F button before the camera pans to the boss. Don't mash it wildly like I did originally, but slow and steady. When I mashed the button wildly, the camera would pan to the boss and pan out in a second or two and the boss would break free. However, if mashing the button while the camera is still behind Isaac's shoulder, it should work.

Also, we shouldn't be doing this. Visceral should fix the **bleep** game already...

In the end I had to lower all my settings and when it panned to the boss I had to tap the correct key then tap a random key and even still it took me way to many tries. All I can say if WTF!!!

Finally done this after 5 nights, Turn of v-sync, low graphics, min resolution, windows full screen, tap 'F' key slow when on the snow beast.
