In 5 on 5 Team PvP games, if I see an opposing player's titan die, I type out in the public chat, "BOOM!" to taunt the opposing team. However, that isn't as satisfying of a celebration as it should be.
I think it would be a nice addition to the game if it featured a global effect for when a titan dies. Perhaps a loud explosion sound with the map shaking for 1 second and a voice prompt either lamenting (*"An allied titan has died!"*) or celebrating (*"Enemy titan go boom!"*) the death of the titan.
