If the roll is successful, the player character gets forced to leave the world map screen to face the situation. The player character's speed may be increased by possessing a special perk, or driving a vehicle (only in Fallout 2).Ībout every 24 hours of travel, the game "rolls" a check for random encounters. "Mountains" are the slowest, and "ocean" sectors are impossible to travel across. "Desert" and "Ruins" sectors are the fastest to travel across. Travel speed across the world map is determined by the sectors it's comprised of. In Fallout Tactics, the player character's location is marked by radiation trefoil, and no tracing is available. In Fallout and Fallout 2, the player character's location is marked by a red cross icon, and the path is traced by line strokes (the stroke length hints at player character's speed - the longer they are, the more time it takes them to travel through that particular sector). To move the player character across the map, they have to click at any area they not currently at. When stationary, the player character's location is marked by an icon in an inverse pyramid, clicking on which takes them to the location they are currently at, which does not have to be a specially designated location - the player character can make stops anywhere on the map to perform actions such as relieving themselves of unnecessary equipment, changing or reloading the weapons held, or administering drugs to themself or one of their companions.

In Fallout Tactics there is a total of 26 locations and 29 random encounters. In Fallout 2 there is a total of 21 locations.

In Fallout there is a total of 12 locations. When they leave a location with intent to travel to another one (typically located far away, due to the Fallout world's extremely low population density), they are presented with the world map. The world map's primary function is to enable navigation for the player character's travels. In Fallout, Fallout 2 and Fallout Tactics, the world map is a bird's eye view map of the landscape of the games, divided into a matrix of square-shaped, equally sized sectors.
