Mastering OSCAR's Demise: A Guide to Killing the Boss in CoD BO7 Astra Malorum (2026)

Navigating the treacherous waters of Call of Duty Black Ops 7's Astra Malorum map can feel like a relentless grind—especially when the formidable OSCAR keeps crashing your zombie-slaying parties! This roaming boss enemy, lurking on a skull-shaped island floating around Saturn, brings a whole new level of intensity compared to the Ashes of the Damned map. His deadly arsenal and near-invincibility make him a thorn in the side of even seasoned players. But fear not, fellow gamers; we're about to dive deep into the strategies that can finally put an end to his reign of terror. And trust me, mastering these tactics might just turn the tide of your survival runs. But here's where it gets controversial: is taking down OSCAR a game-changer that rewards clever planning, or does it feel like an unfair shortcut in a mode that thrives on chaos? Stick around as we unpack every detail— you won't want to miss this!

First off, let's break down what makes OSCAR such a menacing foe. Unlike typical zombies, this guy moves at a sluggish pace, giving you plenty of wiggle room to dodge him by simply circling the map. However, his attacks pack a serious punch. He deploys protective UFO drones that swarm around him, acting like a shield you must dismantle before landing any meaningful damage. On top of that, if he tags you with a shot, it triggers a horde of zombies to zero in on you relentlessly. For beginners, think of it as a boss fight where survival hinges on smart evasion and timing—rushing in blindly is a surefire way to get overwhelmed. And this is the part most people miss: while OSCAR's slow speed lets you kite him easily, his unpredictability can disrupt entire teams, sparking debates on whether he's a thrilling challenge or just plain frustrating.

The good news? OSCAR isn't immortal. You can eliminate him using specific traps scattered across the map, though it demands coordination and preparation. Each method requires gathering components and positioning OSCAR precisely, making it a rewarding puzzle for strategic minds. Importantly, these traps are one-and-done per round, so timing is everything—activate them when he's nearby to avoid wasting the opportunity. Successfully taking him out not only clears the path but also rewards you with the LGM-1, the latest wonder weapon, dropping right from his defeated form. Imagine wielding that power-up to dominate the rest of the undead horde—sounds epic, right?

Let's start with the most straightforward approach: harnessing the sun's deadly beam in the Pack-a-Punch room. Begin by collecting the harmonic components hidden around the map—these are essential keys that power up the area. Once you've gathered them, head to the organ next to the Pack-a-Punch machine and use the components to restore power to the room. From there, keep an eye on the walls for moving mechanisms; shoot them in the sequence they activate, like following a rhythmic pattern in a high-stakes game of whack-a-mole. When OSCAR approaches, interact with the telescope beside the organ's keys and aim your crosshair directly at the sun in the sky. If the view kicks you out, just re-enter the telescope immediately to realign. This unleashes a scorching beam of sunlight onto the central platform right in front of the organ and Pack-a-Punch, vaporizing OSCAR instantly the moment he steps into it. For newcomers, picture it as setting up a solar sniper rifle—precise and powerful, but requiring that initial setup to shine. But here's the kicker: some players argue this method is too easy, potentially unbalancing team dynamics, while others praise it as ingenious environmental storytelling.

Another route involves the cryogenic blast from the museum's rocket model—a chilling counterpoint to the fiery beam. Hunt for Absolute Zero shards by locating Aetherium Crystals dotted across the map and blasting them with a weapon equipped with the Cryofreeze ammo mod. Each crystal yields a shard, and you'll need three in total. With your collection complete, make your way to the museum and activate the rocket model near OSCAR's position. This starts a countdown timer, building anticipation like a ticking bomb. As it hits zero, ensure OSCAR wanders behind the rocket's rear end, where an icy explosion erupts, freezing and obliterating him on the spot. Beginners might find this method forgiving, as the countdown gives you a window to herd OSCAR into place, much like luring a boss into a trap in other games. Yet, controversies arise here too—is relying on environmental hazards 'cheap' gameplay, or does it encourage map exploration that adds depth to the experience?

Finally, for the laser trap in the Luminarium, you'll assemble a makeshift device from scavenged parts, turning the room into a high-tech death zone. Gather three items: first, take down one of OSCAR's orbiting UFO drones with a shot, then scoop up the wreckage from the ground. Next, target Tessie's front bumper (that's the bus on the map) with a Pack-a-Punched weapon to snag the car battery—think of it as juicing up a supercharged gadget. Lastly, scan the outdoor areas for a flickering lamppost; shoot it to drop the wires, adding that final electrical touch. Combine all these in the Luminarium's projector, and activate the laser trap. When OSCAR enters, the beam does the dirty work, zapping him in an instant. This scavenger hunt aspect clarifies for beginners how CoD integrates storytelling with gameplay, rewarding observant players. And this is where opinions diverge wildly: critics might call it convoluted and time-consuming, but fans see it as a satisfying payoff for thorough exploration—does it enhance replayability, or just frustrate rushed gamers? And this is the part most people miss: each trap's uniqueness ties into the map's sci-fi theme, subtly nodding to astronomical phenomena like solar flares or cryogenic tech, making the kills feel narratively rich.
