Apparently, Sony recently ran an "internal competition" regarding Ghost of Tsushima. As @Birdman_Drew -- game designer at Horizon developer Guerrilla Games -- explains, the first 50 employees to obtain the the title's Platinum Trophy were rewarded with a nice little prize.
Arriving in a seriously neat wooden box, the top 50 Platinum hunters got a lovely looking replica sword guard for their trouble. It's based on the default design of Jin's blade in Ghost of Tsushima, complete with stormy clouds and lightning bolts.
Pretty cool, huh? We wonder how many of these internal competitions Sony has...
