Chapter 2

In Chapter 2 of the Passing, when you get to the bar with pool tables, where there is a staircase to your left and a room to your right, go into the room and on one of the walls it says:

Otis,

Out of film, helicopters not coming
Zombies too fast. Not gonna make it.

Frank West

Any player of Dead Rising will recognize Otis as the annoying janitor, and Frank West as the protagonist of Dead Rising.

(For this you will need a ninja sword or machete) On the dark carnival campaign in front of the stadium look around and you'll see an arcade game called "stache wacker" if you press X it will turn on and a bunch of little mustashios popping in and out so just hit them with a gun or melee weapon. Once you get about 40-45 hits the machine will break and alert the horde but you do get the achievement.

Tips for survivors on versus:

1. Communicate–Always use mikes and talk to your team.

2. Stay together–Never stray off or run ahead.

3. Steer clear of Witches–They incapacitate instantly.

4. Healing–Do not heal when your health bar is yellow; heal when red. If someone else is weaker and they do not have a health pack than heal them.

5. Weapons–Grab a different weapon than others. Reload when safe.

6. Grenades–Do not throw a grenade at another survivor, its just plain rude.

7. Tanks–Tanks are BA's and can do a lot of damage. Separate from the Tank. If someone is down than the rest of the team needs to distract the Tank while one goes to revive him/her. Try to light it on fire; it will burn until it dies.

8. Weapon Upgrades–Do not deploy frag rounds or incendiary ammo away from everyone else. Make sure everyone sees it.

9. Look back–Enemies spawn behind you too.

10-Smokers–Smack the strangled survivor using LT.

11-Hunters–Do not smack off; Hunters do not need to recharge before attacking. It may jump on you next.

12. Jockeys–Do smack off; Jockeys need to recharge before jumping again. If you shoot them than aim high otherwise you would just shoot their victim.

13. Chargers–If you see one try to dodge if possible. Serpentine maneuvers and jumping help.

14. Boomers–If you see one that has not puked on you yet than get some distance and shoot it. If you have been puked on than hide in a corner; a melee weapon is good here.

15. Spitters–Do not run through an acid patch for any reason what so ever. Say "NO" to acid!!

16.Friedly fire–Do not shoot other survivors, even if they p!55ed you off. If you are in front than crouch; it allows people behind you to shoot and it improves your accuracy.

Tips on killing the survivors:

1. Spawning–Spawning in the right spot is key. Some infected are better in front of the group and some are better behind. At the start of a level it may be best to spawn in the Safe Room after the survivors leave.

2. Kill stealing–Never steal a kill. If someone has trapped a survivor than do not take that kill. Infected than can steel kills are: Jockey (only from Smoker) Hunter (from anything but a Charger), Charger, Boomer (when it stands too close and explodes), Smokers (only from a Jockey), and a Tank.

3. Team work–Coordinate your attacks, talk with one another.

4. Stay Hidden–If you are wait to ambush or are recharging than hide. You would be surprised on how well you stick out.

5. Car alarms–Get near a car with an alarm. Sometimes they miss you and hit the car.

6. Fire–Fire hurts. A lot. You will burn until you die. Stop, drop and roll will not help you.

7. Ambush–A well timed and planed ambush usually takes them out quick.

8. Boomer–The Boomer has very little hit points. Hide and ambush, do not charge. A fat zombie can only run so fast. If you puke than say around the survivors, if you explode than you will coat them in that dripping fluid that the common infected just love. Do not stand too close to a survivor that is pined. If you get shot than the explosion frees the survivor. The Boomer is better spawned in the front.

9. Charger–The charger is fast, strong, and powerful. Before you hit RT to charge, tail behind the target to insure a good hit. A Charger will carry a survivors until it hits something or runs out of energy. It can also hit more than one survivor. The first is pined and the rest fly in the air. If you are playing a map with a cliff than a Charger can hit a survivor off the cliff causing suicide and an instant kill. Even if you miss as the Charger it can hit hard by pressing LT. A Charger is better in the front.

10. Hunter–A Hunter can leap in the air and pounce a survivor. To leap far aim up. A Hunter can hit hard but does not have much hit points. It can also pounce on uncompensated survivors. A Hunter us better on high ground or behind.

11. Jockey–The Jockey can jump on a survivor and carry him or her. Use it to carry a survivor into an acid patch or away from the group. Do not carry it into fire; the fire will do more damage to you than the survivor. You can also carry a savior off a cliff. This will kill you but it will incorporate the survivor. A Jockey is better in the back.

12. Smoker–A Smoker will lash its long tong at a survivor and drag them away. They can hide on roof tops and still snag a kill. Smokers are best on roof tops or in the back.

13. Spitter–The Spitter can launch a lump of acid that forms a large puddle that cause major damage. Use it to spit on survivors that are pinned, uncompensated or on small walkways to from chock points. If you die than a small puddle of acid will form. Use that to your advantage. A Spitter is better on higher ground or in front.

14. Tank–The Tank is the Chuck Norris of the Zombie World. It has massive hit points and damage. A healthy survivor can run faster than a tank though. Do not let them surround you, do not chase a healthy survivor in an open area, and do not smack a teammate's victim. A Tank can throw chunks of concrete at saviors but it takes time. A Tank can smack a survivor off a cliff causing an instant kill or smack a car on a survivor causing incapacitation. If you do not attack the survivors than you will lose control.

The First Chapter of Any Campaign with a JukeBox in it

If you first start a campaign and happen upon a lit up jukebox, walk up to it and press X. There are a few songs to be played, but if you hear a song that starts with "Hey there, Tom, it's Bob" or something along those lines, keep playing it..

After a bit, the singer and background zombies will yell out "Allll we wanna do is eat your brains!!" and the horde will start attacking!

Don't know if it works every time, but I tried it twice and it happened at the same point in the song.

Second part of the Parish campaign

Once you are off the boat head up the ramp and you'll see a barricade with barbed-wire at the top. Jump up on top of that and you'll see a gib sign right behind you. Face away from the sign looking down at the water, jump forward just a little bit and it will force you to hang from the sign instead of the barricade over top of the water. Someone will help you up and you will be on top of the sign.
