During the Event, all weapons except for the Rookie Machine Gun were completely nerfed, removing all their stats! The Rookie Machine Gun, however, was greatly buffed, making it the first weapon in Respawnables to have 4 bars of all stats! The Event focuses on getting kills and running around in Free For All, and since all weapons were nerfed, the only weapon that should be used is the Rookie Machine Gun.
It's also the first Event that modifies the bots, including Whiplash!
It is the first event to make all the other weapons besides the Rookie Machine Gun to have 0 stats (while enhanced/buffs its stats to 4 bars for each attributes!), meaning that all other guns will deal no damage!
Even after the event ended, apparently there was a glitch that allows a few player's Rookie Machine Gun to still have a maxed out stats (4 bars for each attributes!), while for other players, the weapon's stats go back to normal.
