Here are some hints that can help you when playing this map :

- I recommend playing this map with friendly fire turned off, player deaths decrease the final score.
- The number of zombies depends on the number of players in the level, so if you play with lots of players/bots it's very important
  to work and stay together.
- The map has three cheats you can activate, however keep in mind that if you activate one of them you will get a "Cheater" rank.
- The handgun can deal headshot damage.
- If you use the minigun your walking speed will be decreased, but if you jump then you will keep your original speed.
- The grenade launcher can be charged, the more you charge it, the faster the projectile will be.
- Try to explore the level as much as possible, you can find ammo stashes and also mag extenders that increases your weapons max ammo.
- The water areas in the manor area can heal you, except for the sewers of course.
- To interact with objects you have to use the "grab" button (G by default), you can also use this button to grab decorations like the
  small wooden boxes or the explosive barrels, but you must use a weapon that is hold with one hand, like the handgun.
- Make sure to unlock the sewers entrance in the manor, this is a great shortcut to connect many places from the city.
- The best weapon to fight the female zombies or lurkers is the minigun, to fight the male zombies is the sniper.
- The best weapon to fight the Zombie Brutes is the sniper, however if you do a headshot the brute will go berserk and start running towards
  you and then kill you with its melee attack, to prevent this attack the brute from a corner so the brute can't see you directly.
- A dirty trick to beat the manor ambush very easily is to go to the top of the fireplace inside the manor and go to the farthest corner,
  if you are there you will notice zombies won't be able to reach you. If you go to that place from the very start of the ambush then you
  can save Myoko, as long as she doesn't intervine, kill a bunch of male zombies and then wait for the ambush to end.
- To save Myoko you have to prevent her from interfering during the ambush, stay inside the manor and try to stay in the lower floor as
  much as you can (if the zombies go to the next floor Myoko will intervine), if you are playing with bots stay on the top of the area
  where the staircases are. If Myoko starts fighting the zombies on the lower floor, go outside as quickly as possible and fight the
  zombies as much as you can, if Myoko leaves the manor, she will probably die.
- Keep Eddy alive, since the weapon shop is the best checkpoint to give you all the weapons quickly. So try your best at protecting him.
- If you hear a corpse making a sound, destroy it.
- Use the bedrooms to recharge your health.
- After protecting Eddy I highly recommend going to the hospital next so you can activate the health rechargers.
- Destroy the barricades near the hospital to unlock shortcuts to the Graveyard.
- Go to the rooftop of the hospital and jump to the fence to go directly to the factory.
- The defense barrier of the Graveyard can kill any enemy including the cyborgs and the Zombie Brutes.
- In the hell section after you reach the destination of the big lifts there's a chance zombies will spawn, use the grenade launcher and
  shoot a grenade in the area they spawn as soon as you enter that area. Be very careful since a grenade can kill you instantly.
- Make sure to use the Holy Orb to heal you and your teammates as much as possible, and make sure you have the max number of health
  before touching the red orb in the hell section, since after that the Orb is deleted.
- In the laboratory you will see some cyborg enemies inside stasis chambers, you can destroy them before the cyborgs spawn.
- The health of the professor depends on the number of players in the level, so if you decide to fight him without all the players working
  together, the professor will most likely escape.
- The sniper and the shotgun are the best weapons to fight the professor.
- You can delay the professor from going to the next section if you stand in his way, however be mindful that his melee attack is very strong.
- If the professor is about to escape, you can kill yourself which will stop the professor from reaching the destination, then return to where
  the last stasis chamber is and wait for the professor to go there, then fight him again, repeat the same process if the professor is getting
  to close to the escape area.
