[i] 8 June - Mr.Bozon
Summer is the perfect time to hit the burning hot sand in WayForward’s run ‘n gun-meets-exploration extravaganza! Updates we've added over the past few months include rebalancing of the "undead agent" death mechanic, reduced grind time for pickups, and introduction of simple and traditional Chinese language so more fans can enjoy the game.
Thank you for your support, have a safe summer, and happy mummy hunting!

While GOG's version is the original release dated October 24, 2017, and has NOT received an update ever, sadly.
Bye bye GOG
Ugh... why does this always happen? DRM-free is worthless if a game doesn't get the updates.
