Briefing

Sacre bleu! It's Gaston Boucher's worst nightmare! Just when he though it was safe to buy English meat, his cold room breaks down and now the kitchen is overrun by mad undead cows. There's only one cure - triple inoculation. Depeche-toi. Gaston!

Strategy

On the first wave, run and look out the left door, shoot the cow, then run and look right to shoot the cow, then run back and shoot the other one.

In wave 2, run left shoot the cow. Run white and quickly shoot the cow. Turn round and blast the cow that should be approaching you. Run to the left door, shoot the cow. Run to the right door, shoot the cow. Turn round, shoot the cow that's right in front of you, ago the left door shoot the cow. Got it?

Most of the darts, should be outside your area, if you can, pick them up.

For Wave 3, left, right, right, left, left, right, right, right, left.

For the rest of the waves, look left and right and kill the cows closest. At the beginning still kill one cow, or cows for later on. Keep running away and injecting them. And some cows come through the floor. When you get stuck, shoot them and run. You'll lose a bit of health and kill multiple.
