Martian Invasion

After earning the 'The Buckets of Bolts' achievement, Miles returns home to take a break and hang out. But then Asher and Owen, warrior friends who joined him on the last adventure, come to Miles pleading for his help in defeating Plantera. Things are dicey with Asher and Owen, as they need his help, but often treat him like a third wheel.

Miles agrees to fight Plantera, in order to keep his friends and village safe. And the gang does feel like a trio of warriors after their defeat. Then they encounter the Golem. Being bolstered by their previous win helps them defeat the Golem. And they return home victorious.

But who would have thought their biggest battle yet -- and at home -- would come not from Terrarian enemies, but those from outer space?!
