TSR-Experience (TSRE) is a box with mysterious content that aims to enrich your immersion and your involvement in the main narrative arc that encompasses each scenario. A sort of debriefing with your BOB instructor summarizing the mission accomplished in more detail, while preparing you for the next one.
Experience" is for players eager to deepen their knowledge of the Lore of TS, its characters, history in the stories, enriching the experience.
The best part of all this is that the box "Experience" seems to be able to adapt to your progress when you used, regardless of the order of the scenarios already played or the one from which you go.
With the Blue Cycle, players may wish to simply play one or all in whichever order they choose. Experience provides extra detail to enhance the whole experience for both new players and original fans alike!
