Abandoned Cellar Level 4
The Abandoned Cellar Level 4 (Nickname Aggie cellars) can be accessed from Plaza Sector 1 next to the steps, near the Diamond Real Estate Shop. Another entrance can be found in Plaza Sector 2 opposite Archer & Wesson.
Often considered the best place for starting characters to gain levels, there are kill quests available for Aggressors and they drop trash loot that is good for cloning ammunition using recycling.
The Aggressors do primarily piercing damage.
