Maxed Out

When a character is "Maxed Out", it means that they have every skill currently available in the game.

Additionally, there is "Maxed Out Survivor", which is a player that has all the Survivor Skills, and "Maxed Out Zombie", a player that has all the Zombie Skills.

Most survivors who claim to be "Maxed Out" have not in fact purchased every skill, as few wish to face the challenge of playing a survivor with the skill "brain rot". It seems there are only about 300 such characters (living survivors with brain rot) in Malton at any given time, and a bit over double that many level 42 zombies. The stats page makes it seem there are more, but that is because it counts level 41 characters who are undergoing revivification (or who are alive but infected) as being level 42 survivors.
