The Requiem for a Killer achievement in Batman: Arkham Knight stands as one of the most demanding combat challenges in the entire game. Players must step into the shoes of Batman inside the relentless Iceberg Lounge AR Challenge and build up a massive score to confront Killer Croc. Reaching the required milestone demands incredible patience, precise freeflow movement, and strategic crowd management.

Understanding the Iceberg Lounge Requirements

To trigger the final showdown, players need to accumulate over one million points during a single continuous combat run. Achieving a 20 Rival Point score summons Killer Croc directly into the arena alongside escalating waves of enemies. Maintaining a flawless flow without taking damage is critical to scaling your multiplier effectively.

Mastering Combat Flow and High Combos

Maintaining a long combo streak requires prioritizing high-threat targets like medics, shields, and stun baton users early. Quick-fire gadgets like the Batclaw and Remote Electrical Charge help bridge distant gaps while keeping Batman safe from incoming attacks. Using redirection jumps over enemy heads allows you to maintain momentum and evaluate the battlefield safely.

Managing Enemy Waves and Special Hazards

As your combo score increases, tougher enemy variations including ninjas, brutes, and armed thugs enter the fight. Utilizing special moves such as Disarm and Destroy eliminates dangerous weaponry before it disrupts your streak. Keeping doctors busy or neutralizing them quickly prevents fallen enemies from constantly re-entering the action.

Defeating Killer Croc with Nightwing

Once you reach the target threshold of roughly 1,050,000 points, Killer Croc enters the ring and Nightwing joins the battle. Players must switch between both heroes using Dual Play mechanics while countering Croc's incoming heavy strikes. Defeating the behemoth unlocks the trophy, cementing your status as a true master of Arkham combat.
