Unto The End has received a few updates since it launched and one of the biggest changes to the game has been the introduction of non-violent resolutions to several encounters that previously required the player to engage in combat.

It's worth mentioning that the update has also been rolled out for the console versions of Unto The End, along with several other changes.
