The zombies that appear in Secret Wars are't very gory. They're pretty family friendly considering the levels of violence their predecessors reached.

Not even the two tie-ins centered around the zombies have extreme gore:

In Marvel Zombies, most violence comes in the form of dismemberment, it's violence againt the zombies themselves, and it's not explicit.

And in Age of Ultron vs. Marvel Zombies, the only instance of people being eaten alive by zombies with guts being shown is in issue #4, and only in a few panels from two splash pages.
