Gems of War
is a free-to-play puzzle game that is always receiving new trophies. Many of the title update trophies are tricky, time-consuming or luck-based to earn. For a limited time, the luck can be taken out of earning the Mongo troop for the "Title Update 2"
Through Gems of War
's 12 Days of Christmas event, free gifts are being delivered every day to players' in-game mailboxes. One of the daily gifts
was a free Mongo troop, which is the troop needed to unlock the Game Breaker trophy. While the card was offered for free on its release, that limited-time opportunity ended long ago, and players now have to take their chances getting it in a chest.
If you're familiar with Gems of War
's mail system, then you know you need to act quickly. Unopened mail expires after a period of time. According to commenters on Game Breaker's solution
on TrueTrophies' sister site TrueAchievements, the Mongo mail sent out is expiring on December 21st, so you need to act fast to snag this one.
