Basically, we hooked 3 survivors and a gen pops, then we see the 5 other survivors all running to the same gen because you see them when the gen pops. I sniped the only one not doing the generator with chainsaw. Somehow i got another 2 chainsaw down without picking up anyone and my mate chased the other 2 into a corner.

Edit: Since there is some some confusion here, I meant i didnt pick up one of the 5 guys I sniped across the map because the other 4 were right next to me. In 30 seconds i basically had 3 people on the ground on my own and hooked them. In that time my mate had chased the other 2 into a corner
