If you want to defeat the Gladiator, then you’re going to need to come prepared. This baddie is armed with a shield and powerful mace that you’ll need to pay attention to. Thankfully, there are a few things you can do to increase your fighting chances during this fight.

When the eyes flash green, be ready to dodge and attack.

During the first stage of the battle, the Gladiator will move around you quickly. Use your Dash ability to escape his attacks and look out for the eyes on his shield. When they flash green, the Gladiator is about to attack. Dodge away from the attack and then take a moment to shoot at him as shooting him when he is about to attack can stagger him for a moment, giving you more room to attack.

Watch out for incoming demon spawns, too. While fighting the Gladiator, you’ll need to replenish your ammo and health at times. Use the minions around you to do so, chainsawing or pulling off Glory Kills when needed.

The Gladiator can block incoming projectiles by swinging his flails.

After you reach a certain point in the fight, and have wounded the Gladiator enough, he will drop his shield, and pick up a second flail. When this happens, the Gladiator becomes much more aggressive. Continue to deal damage to him and avoid his attacks while rearming yourself by killing minions. At this point it becomes a fight to stay alive and avoid damage, so keep on the move.The Gladiator will also spin his flails, blocking any incoming projectiles. As the fight continues, watch the Gladiator’s eye now, as it will flash green like the eyes on the shield did before he attacks.
