Yield and ROI are estimates built from community-reported averages, not measured figures, and they exclude the loadout lost when a run goes wrong. Use them to compare keys against each other rather than to predict your own results.
Fred Lee – better known simply as Fred – is the undisputed warlord of the Northridge map in Arena Breakout: Infinite. Season 3 has turned him into one of the deadliest enemies in the game, thanks to smarter AI, unpredictable weapon loadouts, and brutal supporting bodyguards. He isn't a tank you can mindlessly spray down – Fred is a calculated threat that behaves more like a seasoned PvP player than a traditional boss.
