Fly Swatting Simulator
Play as Reinhardt or Brigitte and smash the flies in time!
Or, play as a bug and try to survive!
Rein/Brig gains extra time for each kill.
There is a Rein bot which drops in if the human Rein leaves or if there aren't enough players.
There are also drop in bug bots.
Also has some custom workshop settings to easily configure the gamemode and experiment:
Have fun! ;)
