About this game
TunTun is a co-op comedy horror best played with others. Work together to gather weapons and resources to better help your explorative adventure through a labyrinth of tunnels.
Be warned: As you progress, scarier and deadlier monsters will try to stop you! But with your trusty tools and floppy fools (or whatever you call your friends) you'll be...fine...and you'll have adventures worth telling the next generation!
You're looking for THE GOLDEN MASK. It's the all powerful, incredibly rare, super shiny mask that grants its wearer god powers. If you happen to find that, you, my friend, are the ruler of the tunnels.
But don't get all caught up in the quest for power, have fun! Enjoy the flickering lights, bloodthirsty monsters, getting so turned around you lose your mind--it's paradise!
