Of course, nothing is ever straightforward.
Minecraft: Story Mode - Episode 8 : A Journey's End? throws the gang into the middle of an apparently deadly competition. Surrounded by foes armed with swords and TNT, Jessie's gang strives to survive the immediate threats surrounding them, and, unfortunately, she will be forced to choose to save one of her friends. What Jessie doesn't realize though, is that death in this world isn't permanent. When the group's interference causes the fight to be halted, she learns that this fight is merely a game made to entertain the three Old Builders that rule this world, and when a player dies, they respawn in a cage so that they can't interfere with the rest of the competition.
The Games, which have a similar feel to those found in The Hunger Games, are a set of competitions where teams try to not only survive, but hopefully knock other teams out of the running. For the teams that are completely eliminated, its unknown years of hard labor in the mines in the hopes of another chance to compete. As for the very, very few that win, that team gets its freedom and the ability to return to their own world.
It seems that the only way to make it back home is to continue to compete and win The Games at any cost. Unfortunately, Jessie's team is already down a couple of players.
