All arcades have some playable arcade machines. There are about 2-3 that can be found within the location. Playing with the arcade machines will give the player a Morale boost and Shooting skill boost.
Using the arcade machines will cause time to pass and in that time, zombies will spawn.
It is advised that you have other group members around to guard the character interacting with the machines. If not guarded, the player character will be forced to defend themselves and may be attacked and hurt by nearby zombies.
