🧠 How to Unlock the ContraBloom Laser
The MPC‑25 ContraBloom Laser isn’t unlocked by leveling the weapon — instead, it’s tied to weekly challenges rotated in Call of Duty: Black Ops 7 and Warzone. According to official patch notes, this laser becomes available as a Weekly Challenge Reward, meaning you’ll have to complete six challenges from that specific week to earn it.

Challenges can vary each week and typically span all major game modes — including Multiplayer, Warzone, Zombies, and Co‑Op. These might include tasks like getting a set number of eliminations, completing objectives, or earning medals in matches, so make sure to check the challenge list as soon as the week begins.
💡 Pro Tip: Prioritize weekly challenges early in the reset cycle so you don’t miss them — once the week ends, that attachment rotates out and you’ll need to wait for its next appearance.
⚙️ What the ContraBloom Laser Actually Does
The ContraBloom Laser is not your usual laser sight — it dramatically reduces hip spread and firing bloom, making the MPC‑25 more accurate during aggressive, fast‑paced battles. However, this power comes with notable trade‑offs: it reduces damage range and blocks underbarrel attachments and optics, so it’s best paired with a close‑quarters aggressive build.
In short, it’s a specialized laser for players who like to rush and dominate in tight maps or close‑range engagements, especially in Warzone’s fast zones or small multiplayer maps.
🔄 Why It’s Worth Getting
- 🏃♂️ Better Hipfire: Great for run‑and‑gun styles.
- ⚡ Quick Handling: Boosts mobility when hip firing.
- 🎯 Meta Enhancement: Can elevate your MPC‑25 into a top‑tier SMG for aggressive play.
