3 new flags were added in 0.6.2.1, apologies for such a delay on making this article, as my internet was offline for the last week.
Martoboi:
I’ll be honest, I know nothing about this flag. Will update this post when I learn more about it.
St. Patrick:
Pretty self-explanatory, can be earned in-game for a St. Patrick’s day event until the 20th.
Scavenger Flag:
This Flag can be redeemed on NA by inserting the bonus code “JU5TT35T1NGL01Z” (seriously)
