Radio Tag

Radio Tags are collectable items in Red Faction: Guerrilla that provide some visibility into in-universe matters in the time between Red Faction and Guerrilla. In-game, each of the 36 are easily identified by their foggy orange glow which vaguely resembles fire, as well as the green dot which appears occasionally on the minimap. They can be picked up by the player running over them.

For every three the player collects, the location of a MOAB will be revealed and marked on the map.

Players who gather all 36 are awarded the Lost Memories achievement.
