Aircraft
First Officer's leg. Push and start were normal. We taxied to [Runway] XXL; were cleared to lineup; takeoff. Just as takeoff thrust was achieved; a loud bang was heard and felt from the right engine. Aircraft veered to the right; EICAS (Engine Indication Crew Alerting System) messages were 'ENG FAIL R;' 'ENG CONTROL R;' etc. The Captain immediately took control of the aircraft; maintained centerline and slowed the aircraft. We advised Tower and cleared the runway; accomplished applicable checklists; [and] returned to the gate.
At takeoff thrust; there was a loud bang followed by EICAS (Engine Indication Crew Alerting System) messages relating to Engine Failure. Take off was aborted at 30 knots and returned to gate.
