The summary of ‘Fallout Shelter Free Lunchbox Trick!! Infinity, No cheat, No Jailbreak | Fallout Trick & Glitch’

The video provides a guide on how to exploit a glitch in Fallout Shelter to obtain an unlimited number of free lunchboxes without jailbreaking or cheating. The method requires starting a new shelter since it won't work if the tutorial has already been completed.

Key Points:
1. Create a new shelter and follow the tutorial.
2. Receive two specific quests: "Equip one dweller with an outfit" and "Sell one weapon or outfit."
3. Do **not** complete these quests.
4. The game will keep providing simple quests with rewards including lunchboxes or small amounts of caps.
5. Complete the simple quests such as "collect 50 water," "collect 50 electricity," "collect 50 food," or "level up one dweller" to get free lunchboxes.
6. Continuously receive lunchboxes by repeating these simple tasks.

The video creator advises against using this glitch frequently because the game is enjoyable without it and recommends supporting the game developers instead.
