This early boss encounter on the train introduces you to larger, more durable enemies. The Heavy Robot is heavily armored and wields powerful machine guns. Its primary weakness is its exposed power core on its back. Focus on flanking maneuvers to get behind it. Use your assault rifle or shotgun for sustained damage. Grenades are also effective for staggering it or forcing it to expose its back. Utilize the train car's environment for cover, but be aware that much of it is destructible. Keep moving and prioritize dodging its heavy fire.
