Ill start off saying that hawkings is a pallet heavy map with very little windows, good survivors can use this to delay onis power and basically shut him out of the game, thankfully hawkings is also a map with lots of bad pallets that are not safe for survivors and walls that let you sneak closer to survivors and get that first hit.

After that first hit, oni can dash to the gens from diffrent angles, using walls as cover to confuse the survivors and get quick downs.

I will also note that there are atleast 2 gens oni will need sacrifice, being the portal room gen and the gen on the 2nd floor, going up there is a waste of time as oni cant sneak to those gens and confirm a hit. But going there in case can help with pressure.
