Unfortunately, I don't have any tid-bits of information. But I have found a site that has been amazingly helpful so far, for me at least.http://www.supercheats.com/guides/prototype/
It has videos for almost, if not all of the events, as well as tricks and tips to make those particularly pesky events go by a lot easier.
Below is a video of the event that has been giving me the a lot of trouble. Check the site for many more ^^
Note: None of the work on the site linked is mine. I am just linking it incase others were not aware of it.
Enjoy, fellow achievement hunters!
