If you have been no-lifing Black Ops 7 Zombies lately, you probably are sick of OSCAR already, and you might be the type who messes around in a CoD BO7 Bot Lobby just to work out a plan before going back into a real run. He rolls in like a walking tank, drones buzzing round him, and it feels like your bullets are just there for decoration. You take out the drones, think you are safe, then see that ridiculous health bar still sat there. A few rounds later, he turns up again like nothing happened. If you try to brute-force him every time, you burn ammo, lose perks and usually the whole match, so the trick is to stop thinking “DPS race” and start treating him like a puzzle.
Gear Up Before You Pick A Fight
First thing, do not even start the fight with base guns. You want your main weapon Pack-a-Punched at least once, twice if you can push it, because un-upgraded rounds barely scratch him. In squads, it is way easier to let one or two people run trains while another player focuses on OSCAR, but solo players really feel the pain if they skip crowd control. Grab ammo mods that stun, freeze or stagger the horde so you are not trying to shoot OSCAR while ten zombies chew your ankles. Once you are actually geared, you will notice that holding the trigger and dumping clips into his chest is pretty pointless compared with using what the map gives you.
Using The Sunlight Beam Trap
The cleanest way people are dealing with him right now is the Sunlight Beam trap in the Pack-a-Punch room. It sounds fiddly, but after you do it once or twice it becomes part of the routine. You shoot the steaming valves round the room to spin the machine up, then use the telescope by the organ to line the beam up with the sun. When it is ready, you kite OSCAR into that small platform between the organ and the Pack-a-Punch machine. You do not need fancy movement, just keep him aggro’d on you and circle the space. Hit the trap when he is on the platform and he just evaporates. One flash, gone. You barely use any ammo, and it feels like you have just cheesed the hardest part of the round.
Rocket Trap And Cryo Freezing
If you are bored of zapping him and want something more chaotic, there is the rocket trap by the museum. This one needs a bit more prep because you need the Cryofreeze ammo mod. You go round looking for those purple Aetherium crystals, pop them with Cryofreeze, then pick up the Absolute Zero shards they drop. That part is not hard, it is just easy to forget mid-round. Once you are set up, drag OSCAR down near the rocket, making sure he is behind it rather than off to the side. Trigger the trap while he is in the blast path, and the explosion does the heavy lifting. It is messier than the Sunlight Beam, lots of zombies getting in your face, but if you like big explosions and quick finishes, it is worth the juggle.
Luminarium Overcharge For The Wonder Weapon
For players chasing every unlock, the LGM-1 Wonder Weapon route is where OSCAR turns from a problem into a stepping stone. You have to build up the Luminarium Overcharge with a few specific parts. First, you grab a damaged drone from his little escort squad, so do not destroy them all outright. Then you shoot the hood of “Ol’ Tessie” with a Pack-a-Punched gun to knock out a car battery, and after that you look for a blinking lamppost to get the Aberrant Wires. Slot all this into the Luminarium and it becomes a kill box. Lure OSCAR into the zone, keep him there long enough and watch the overcharge tear through him while you keep the zombies under control. It is slower and a bit more stressful than the trap one-shots, but if you are aiming for that LGM-1 and maybe setting up future runs or even testing routes like people do in cheap CoD BO7 Bot Lobbies, this method pays off in a big way.
