Talon Hunt
The lore to Overwatch is surprisingly deep for those who seek it out with a bunch of different factions and histories to all the characters. Though it has been present since the very beginning no Overwatch game mode has dealt with the war between Talon and the eponymous organization. Though they are now very much rivals, there is no problem with Reaper and Solider 76 teaming up to secure the objective. This shouldn’t change but it might be nice for a game mode to really dive into the conflict.
With Sombra, Reaper, and Widowmaker there are enough players for a 3v3 elimination match where one team has to choose from those three characters and the rest can choose some from the Overwatch. For the first time Overwatch players could fight for and against Talon. To make things fair and balanced it should probably be limited to just three Overwatch characters such as Tracer, Solider 76, and a sniper like Ana or Hanzo (though the latter isn’t technically a member of Overwatch) going up against the Talon trio. Either way it would be a nice way to expand the lore of the game outside of the occasional dialogue exchanges between characters.
