Event trigger and boss stages (Think of "Terraria")

[iicecube]

I wish there is some sort of events trigger or bosses encounter stage instead of waiting counter 7 days till you die.

Much like "terraria" the fun was to powerup the toon and fight for the stages of bosses till endgame which was fun on it own survival game. Those contents can be added into 7 days to die for more excitements than a plain world we only waiting.
