On the subject of looping, I'm sure more issues will turn up once the game launches (they always do), but there were several issues during the beta I noticed that could be potential loop problems. I've seen Jason chasing a person around a car, unable to catch them, a table, a fence (I think they've teased this one being fixed), a couch, and other various objects. This was more obvious with the Jason types that couldn't run as it let the player keep pace ahead of them and avoid being caught, even with the abilities as a lot of them were just long enough to allow the person running away to turn a corner in time to render them useless. So I expect we'll see more and hear more about some other issues once it launches.
I know Gun Media is on a budget, but it would be nice to get one more beta in to pound out some of those issues before release, particularly in the new maps.
