Beyond unlocking perks, weapons, and progressing through the Easter egg quest, light beams in Black Ops 6 Zombies serve as a crucial survival mechanic in Citadelle Des Morts. As waves of zombies grow stronger and more relentless with each passing round, the light beams offer strategic advantages that can help you stay alive longer and gain the upper hand.

Here’s how the light beam system can be used to your advantage during zombie survival:

1. Defensive Buffs via Light

As the game progresses, enemies become harder to handle, and more specialized zombie types (such as armored or raging zombies) will start spawning in higher numbers. This is where the light beams can provide defensive advantages.

In some areas, directing a light beam at specific structures or statues can grant temporary buffs, such as increased damage resistance or enhanced weapon effectiveness. These buffs can be pivotal when facing overwhelming hordes, allowing you to push forward or make a strategic retreat when needed. Always keep an eye out for places where light beams interact with ancient defenses—these can provide much-needed protection during the heat of battle.

2. Light Beams as Zombie Traps

In certain sections of Citadelle Des Morts, you can use light beams to trigger environmental traps that temporarily disable or kill zombies. For example, directing a light beam at a trap in the Citadel Courtyard might activate a set of giant stone pillars that crush any zombies standing beneath them.

These traps aren't just for show—they can significantly reduce the pressure of multiple zombie waves, giving you valuable breathing room. The trick is knowing when and where to direct the beams, as certain traps are linked to specific light emitters.

3. Creating Safe Zones

Light beams can also be used to create temporary "safe zones" within the map. When aligned properly, light beams may activate large, shielded barriers or force fields that block zombie spawns in specific areas. These shields provide a safe haven where you can regroup, reload, and heal without worrying about zombies rushing in.

These barriers typically last for a set period of time or until the light beam deactivates. If you’re running low on ammo or need to gather your team, using these barriers wisely can turn the tide in a difficult round. Be mindful of when the safe zone is about to expire, as zombies can still attack from behind if you're not careful.

4. Reviving Teammates in a Pinch

In high-stakes scenarios, you may find yourself or your teammates downed while in the midst of a light beam puzzle. Fortunately, certain light beam configurations can be used to revive teammates at a distance. For example, directing a beam toward a Revival Crystal—a glowing gem-like object placed strategically on the map—can initiate a revival process, bringing a downed teammate back into the fight.

This revival process isn’t instant and requires a few seconds to charge, so timing is crucial. During this period, you’ll need to clear zombies from around the crystal to prevent them from interrupting the revival.

Using Light Beams in Combination with Special Zombies

As if regular zombies weren't enough to contend with, Citadelle Des Morts also introduces special zombie types that require different strategies to handle. Some of these enemies are particularly resistant to conventional weapons and can overwhelm even the most prepared players. Here’s where light beams come into play.

1. Defeating Armored Zombies

One of the toughest enemies you’ll face in the Citadel is the Armored Zombie. These zombies are shielded by a thick layer of metal armor, making them resistant to most attacks. However, light beams can weaken or disable their armor temporarily.

By directing a beam toward an armored zombie or a designated “weak spot” in the map, the light will cause a temporary energy burst that disables the armor, allowing your team to deal damage directly to their weak points. The timing of this is key—if you wait too long, the zombie will regenerate its armor.

2. Dealing with Energy Absorbing Zombies

Another unique enemy is the Energy Absorbing Zombie. These creatures will try to siphon energy from the light beams you’ve activated, weakening the beam’s power and potentially resetting your puzzle progress. To counter this, you need to direct a powerful burst of energy at the zombie from a nearby light emitter. This will stop the energy drain and keep your beams intact.

These special zombies are usually accompanied by a noticeable visual cue (glowing eyes or a pulsing aura), so be ready to deal with them quickly when they appear. If left unchecked, they can wreak havoc on your light beam setups, making the entire process more difficult.

Light Beams and the "Nightmare" Mode

Citadelle Des Morts also features a brutal Nightmare Mode where the entire map becomes more treacherous. In this mode, light beams take on a more integral role, as they become your primary source of both offense and defense.

In Nightmare Mode, the undead not only grow in strength and numbers but also become faster and more aggressive. The usual zombie tactics won’t be enough, and you’ll need to use the light beam system to unlock special enhancements. These enhancements include:

• Enhanced Light Beam Powers: Certain light beams in Nightmare Mode allow you to shoot beams of concentrated energy at enemies, dealing massive damage in a straight line. This is particularly useful when dealing with large swarms of zombies or powerful special zombies.

• Zombie Disorientation: Directing a light beam at a specific point in the map will disorient zombies, causing them to become temporarily confused and lose track of players. This gives you a few crucial moments to escape or regroup.

• Light Beam Barricades: In Nightmare Mode, certain areas can only be accessed or survived by creating makeshift barricades with light. These barriers will protect against both zombies and environmental hazards, allowing you to complete complex puzzles in peace.

Maximizing Light Beam Synergy in Nightmare Mode

The most successful teams in Nightmare Mode are those who work together to maximize the synergy between light beam mechanics and their weapons. Here are a few tips to get the most out of your light beam usage:

• Coordinate with Your Team: In Nightmare Mode, light beams become more dynamic and are often necessary for team-wide survival. Have one player focus on generating the beams, while others direct them and fend off the zombies.
• Prioritize Light Beam Buffs: The buffs unlocked by light beams can be game-changing in Nightmare Mode. Perks like Double Tap or Deadshot might seem small, but they can make a world of difference when fighting endless waves of increasingly powerful zombies.
• Time Your Attacks: In high-intensity modes like Nightmare, timing is everything. Make sure to align your light beams and deal with special zombies in synchronized intervals to avoid being overwhelmed.
