Gemcitabine and Ex Vivo Expanded Allogenic Universal Donor, TGFβi Natural Killer (NK) Cells With or Without Naxitamab (Danyelza) for the Treatment of Patients With Metastatic, GD2 Expressing, HER2 Negative Breast Cancer

Inclusion Criteria: * Patients must have histologically or cytologically confirmed, HER2 negative metastatic breast cancer that is historically GD2 expressing (e.g., triple negative breast cancer, metaplastic breast cancer, high grade 3 estrogen positive breast cancer at initial diagnosis) with available archival tissue. Well differentiated neuroendocrine tumor (NETs) are not eligible for this trial since GD2 expression is unknown. GD2 expression is not required for eligibility but a primary tumor paraffin block is required at enrollment for assessment of GD2 expression * Patients must have measurable disease, per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) for the evaluation of measurable disease * Patients must have received at least one prior treatment for metastatic disease and progressed on treatment or been intolerant to treatment * Female or male \>=18 years * Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 * Absolute neutrophil count \>= 1,500/mcL (\> 1.5 X 10\^6/L) * Platelets \>= 100,000/mcL * Hemoglobin \>= 9 mg/dL (transfusion to obtain hemoglobin \>= 9 mg/dL within 24 hours prior to dosing is allowed) * Serum creatinine =\< 1.5 X upper limit of normal (ULN) or measured or calculated creatinine clearance (CrCl) \>= 60 mL/min for participant with creatinine levels \> 1.5 X institutional upper limit of normal (ULN) (Glomerular filtration rate \[GFR\] can also be used in place of creatinine or CrCl) * Patients must have adequate hep…
