Sliding into the opening stretch of Containment feels rough straight away, and you notice it even more if you have not been warming up in a CoD BO7 Bot Lobby. The whole place is packed with cameras and those twitchy turrets that love to ruin a clean start. You do not want to sprint in like you own the place. Most players get spotted because they rush a corner or forget to check a blind spot. Move slow, break sightlines, and keep your noise down. Once you slip inside, the build‑up gets tense in a way that makes every step feel like you are waiting for something to jump out.

Sabotaging the Cargo

The job changes quick when you hit the shipping floor. You go from sneaking around to blowing apart crates and modules as fast as you can. It is a weird rhythm at first. You hit a target, duck back, reload, and then edge out again. Bigger mags help a ton here, because the firefights get messy and you do not get many safe moments to swap gear. A lot of players burn ammo too fast and then panic when a turret snaps toward them. Keeping calm makes a bigger difference than you think.

Breaking the Defenses

Once the alarms kick off, the facility feels like it wants you dead. The automated turrets in this section react almost instantly, so taking them out from an angle works better than trying to brave the open floor. I found that moving in short bursts helps you dodge the tracking just long enough to land a few clean shots. It is one of those times where you realise how much the game punishes standing still.

Raising the Reactor

The bioreactor room is the part that usually throws people. You turn one wheel and the place wakes up like a beast. While you are trying to get the core lifted, you have squads pouring in and Kagan dropping his mech units like he is trying to prove a point. Shooting their front plates is pointless. Everyone eventually figures that out. Aim for the legs or tag them with explosives. Slowing them buys you just enough time to keep the reactor sequence going.

Fighting Through the Collapse

Once the core hits critical, everything gets weird. The mist that fills the halls messes with your view and the HUD flickers like it is losing its mind. You start second‑guessing every shadow. The pressure shifts make your aim wobble too, which is the last thing you want when enemies keep pushing. Watching the minimap becomes almost instinct here, because you cannot trust your eyes.

The Run to Safety

The escape run is pure chaos. The whole building is falling apart, and you are low on ammo, low on patience, and just trying not to slip up. Debris rains down, the path shifts right under you, and you do not really get time to think. You just push forward and trust your muscle memory, especially if you have been practicing in a cheap CoD BO7 Bot Lobby. This final sprint always feels like the game is daring you to blink.
