Entry location: Final boss
Sullivan uses a handgun, advanced hand-to-hand fighting, and throws flares that call missiles.
Firstly, in the Yucatan casino maintenance room, there is a spitball gun. Find the room with the tiki torches, combine the gun with one then save. Load the game and repeat (need 2 of them).
You will need at least 4 items of food that heal 4+ slots.
Go up the elevator, ignore the zombies except the ones on the stairs (it's where you'll be fighting from). Activate the cutscene, turn around and go behind the hedge/fence. Take shots at him till he dies, healing as needed.
Beware the flares.
- 2 firespitters
