Using a Rat Stick at level 1, one of the weakest weapons in the game, a player can determine precisely how strong zombies are in comparison to each other. Frank at level 50 kills the zombies much faster. For example, it takes 6 hits to kill a fat man with a rat stick at level 50, and 15 times at level 1. Nighttime is at 7:00 pm every day, when the zombies eyes become red, making them "stronger, faster, and much more violent"
There are less than thirty different zombies in Dead Rising. It is not uncommon for Frank is attacked by quadruplets (the same zombie generated four times together). Below is an attempt to photograph all of the zombies in Dead Rising, with unofficial nicknames.
Frank can interact with zombies through the load screen doors, shooting them, throwing items at them, etc.
Zombies ignore cult members, possibly because their outfits mask their human smell.
Zombies evening aggression is from 7 pm to around 7 am daily.
If Frank stays on one load screen, the zombies never lose their red eyes and evening aggression.

↑Although it takes 8 hits to kill the thin woman during the day, the actual number is probably 7.5 because zombies are exactly twice as difficult to kill at night. The thin zombie woman is killed after 15 hits at night. One half of 15 is 7.5.
