Flashback Mania is a trophy for Metal Gear Solid 4: Guns of the Patriots. To earn it, the player must view all of the flashbacks (prompted by an "X" during cutscenes) in the game. Progress is saved in clear data, so a missed flashback can be seen on a repeat playthough.
The player can skip the rest of a cutscene after they have gotten all of its flashbacks, and stil recieve the trophy.
The flashbacks the player got will still count as long as they save afterward.
Audio flashbacks do not count toward the trophy.
