Warhammer: Vermintide 2

This achievement is for shooting all ten crows on Khazukan Kazakit-Ha! However, this can be cheesed, as multiple shots on the same crow count until it despawns. Using an outcast engineer you can shoot the first crow, perched atop a log not far from spawn, 10 times to pop.

For a free solution, the repeating handgun can shoot a crow 6 times before it despawns so either shoot the first crow and the second, located near a skeleton on a slightly elevated ground on the main path, healing draughts spawn near it on lower difficulties so it shouldn't be hard to spot.

Additionally, using 2 repeater handguns, Bounty Hunter and Kruber can most likely be used to shoot the first crow 10 times, this will require co-op.

Do note the crows will fly away if you get to close, and that a small degree of accuracy will be required. I'd recommend pacing the repeater shots instead of just spamming.

I'm adding a short video guide of the "exploit" allowing you to shoot the first crow 10 times as opposed to finding all 10 crows. It is easily achievable with the Outcast Engineer class with a minute or two of effort.

Video shows the short walk from the beginning up to a "bush" that I stop at. Aim your reticle and prepare to attempt to hold it in place while firing. There are a couple of skills, like Linked Compression Chamber, that could make the aiming easier - but it's honestly incredibly easy.

Please let me know if this method is patched out and I'll remove the solution.
