Breather Boss: Teddy is probably the easiest boss in the entire game. All you have to do is deactivate his security system while avoiding his drones and a few zombies, nether of which are very difficult (though the aforementioned drones can be bit of a problem if you're not quick enough). Also, you don't even have to fight Teddy directly (he suffers a heart attack as soon as you get to him).
Base-Breaking Character: Nick Ramos. there those who don't think he is on par with Frank West or Chuck Greene in terms of being a Dead Rising protag, and those who think he's a welcome change of pace due to him being a Cowardly Lion.
General John Hemlock, Secretary of Defense, oversees the martial law over the zombie outbreak in Los Peridos, and is working alongside Marian Mallon, acting President in the absence of Sonya Paddock. In reality, Hemlock had Paddock kidnapped and forcibly infected with the zombie parasite, so that he could take over. Hemlock plans to firebomb the city it in a week if there are no signs of organic life, and he uses his psychotic henchwoman Sgt. Hilde Schmittendorf to kill civilians. His plan is to extract King Zombies from the city and use them to start and control outbreaks all over the Eastern Seaboard to continue imposing martial law and leave him as the de facto dictator. When Mallon disrespects Hemlock, he kills her by throwing her off a building.
Albert Contiello is a sadistic surgeon who represents the sin of Greed. During the outbreak, Contiello takes to abducting survivors and begins performing surgery on them without anesthetic to harvest their organs for the black market. When he captures Nick Ramos, Contiello injects him with a hallucinogen that makes him hallucinate everyone around as Contiello, putting other innocent survivors at risk.
Crazy Awesome: Some of the Psychopaths are this, such as the Warrior Monk-like Zhi and Diego using a fully functional astronaut suit to attack Nick
Crosses the Line Twice: Zhi beheading himself after being defeated is pretty disturbing...until his head hits the ground, revealing a rather Narmy look on his face.
Dylan's whole spiel: the guy is a psychotic fetishist with a creepy appearance. Then you get to his male genitalia-shaped flamethrower.
Ear Worm: A majority of the boss themes are very catchy despite having creepy moments in them. The best example of this is the lust theme which is both catchy and somewhat unsettling to listen to during the fight due to the chanting "when was the first time you had sex" as well as the laughter.
Ensemble Dark Horse: Dylan tends to show up in artwork. It helps that he's one of the more outlandish Psychopaths.
Fetish Retardant: Dylan, on the other hand, is a deliberate example of this, with his mixed sex gear, freaky demeanor, and sharp teeth. Although, YMMV, considering his Ensemble Dark Horse status mentioned above, he does manage to be appealing to some people.
Timer alterations. The strict time limit placed on the player was always one of the most controversial gameplay mechanics in the series, with about half the fans calling it a Scrappy Mechanic that gravely restricted the player's freedom and the other half arguing that it was a key part of the game's flow that forced the player to think about their next move. As such, when this game made the timer far more lenient, extending it to six days instead of three, the reaction was decidedly mixed, though even those who didn't like the change didn't mind too much. Plus, there was an optional difficulty to make it more like the previous games. Then the fourth game dropped the timer completely, and one of the most common complaints about the resulting game was that, without the timer, it had lost a key part of what made the series unique, turning into a cookie-cutter Wide Open Sandbox game.
Also, the fourth game's removal of the Psychopaths, people who had snapped and gone postal due to the stress of the zombie outbreak and served as boss battles, was widely criticized, with their replacement, the Maniacs, being broadly unpopular for lacking the distinctive personalities and introductory cutscenes that the Psychopaths had. This game had already begun toning down the Psychopaths, with most of the fights required to progress through the story being with conventionally evil military figures or gang leaders, and only six optional Psychopaths along the side. While the conceit of having seven different Psychopaths based on the Seven Deadly Sins (the six optional Psychos, plus the story-critical Albert the sleazy surgeon, who represented Greed) was applauded by some fans for providing a theme to the boss fights, others found themselves wishing that there were more of them scattered throughout the game, especially in a setting that served as a pastiche of the ripe-for-satire Los Angeles. Dropping and replacing them altogether in the fourth game wasn't a big leap.
Fridge Brilliance: The Psychopaths are all named styled after the Seven Deadly Sins, right? Not many people know about what some Eastern Orthodox denominations consider to be the 8TH sin: Despair. This role is filled by the self proclaimed "realist" Red, who has long given up on the good fight and is willing to sell out everyone for a quick buck.
Nick being The Immune orphan makes perfect sense when you realize the symbolism of the number 12. In traditional Christianity the number 12 is the perfect number, symbolic of God's authority on Earth. Jesus had 12 apostles, Jacob had 12 sons.
Fridge Horror: It may seem odd to you that most of the safe houses in the city are infested when you first reach them as Nick, forcing you to clear them out before you can use their facilities. If you play the Operation Broken Eagle DLC, however, one of Adam's side quests is deliberately attacking the safe houses with a customized bioweapon, each of which is locked up and clearly occupied by living survivors. You're the one who infested those safe houses.
Game-Breaker: The Ultimate Grim Reaper. It launches a cluster of bombs with each swing, allowing you to gain PP extremely quickly. The bombs are limited by ammo, but since you can replenish it by just killing zombies, this weapon can go a long way.
The Electrofire Staff in Fire-Mode can also make level grinding a breeze, according to this video, and it's easier to make than the Ultimate Grim Reaper (requiring two blueprints instead of three, as well as materials for it becoming common).
The ZAR combo gun, made from a shotgun and assault rifle, has more ammunition than both its ingredients put together, randomly sets its targets on fire, and inflicts decent damage even on psychopaths. Since you can find both shotguns and assault rifles on zombie cops or soldiers, you can easily keep ZARs in your inventory throughout most of the game, and a clean headshot from it will even put down "super" zombies like convicts and firemen.
In addition, with only one skill point, that's spent in the in the "guns" rigging skill, any type of gun will be usable for for the combo, meaning you can pick up two of any gun type to make it. This can mean two pistols, which is surprisingly common in even the same area as each other, or pick up a random gun, such as a flare gun, run around for a minute, find the other gun type, and make it from that. In addition to power there is reliability as well with a simple level up.
Also, it's found in the police station. The easiest way to get it is, if you have chapter 3 of untold stories or the one as the gang leader, start that and he'll come across it in his quest to escape the station.
Speaking of witch, the untold stories are wonderful for picking up all the collectibles. Due to time passing based on plot rather than playtime, it can be easy to run around as a character and take your time snatching up blueprints, collectibles, and some extra PP for levels. The disadvantage is there are no safe zones for any of these characters, so no lockers, but after a few hours playing the normal game even a new player should be able to get along just as well without that boon.
Good Bad Bugs: if you defeat a boss when he/she is electrocuted/set on fire, he/she will still be affected during the following cutscene. Which can be morbidly hilarious.
In spades, mostly thanks to the game's exclusivity to the Xbox One alienating many fans. For months, the Dead Rising Facebook feed contained virtually nothing but pleas for DR3 to be ported to other systems. It died down slightly after Microsoft walked back their more controversial features on the Xbox One, but many Dead Rising fans are still bitter over Capcom going exclusive for one reason or another. It likely doesn't help that Dead Rising 2 was made available for other platforms. Alleviated somewhat when the game was announced for the PC at a later date as the Apocalypse Edition, but only somewhat since people have been reporting performance issues and crashing with it.
The more muted color palette hasn't gone over well with many, with Yahtzee (who loved the last game) citing it as the biggest reason he's not interested in the sequel.
Some people didn't approve of the Darker and Edgier overtones. And while the producers still kept in the wacky costumes and over-the-top weapons, as well as having a funny moment here and there, a common complaint is that the humor comes across as forced given the tone.
Moral Event Horizon: Hilde, who is supposed to be ensuring survivors' protection, has a pleading man's wife murdered and then snaps his neck pretty much For the Evulz.
General Hemlock crosses this when he orders President Haddock to be forcefully infected with a parasite and then turned on a civilian to ensure he'll assume martial law, and thus total control.
Marian Mallon murdering Diego just so she could see if he was the cure...gruesomely.
The Secret Ending reveals that the outbreak of the game was caused by Isabela Keyes so she could find a cure and become a hero for all time, not giving a damn about any "inconsequential" lives lost in the process.
Most Annoying Sound: As you contend with Teddy (the Sloth Psychopath) and his drones, he whines, complains, and taunts you in such an annoying manner.
Once again, letting the main character wear anything during cutscenes. Moments that are suppose to be dramatic or scary can be ruined by Nick in a mankini.
Similarly, the blood splatter mechanic. The worst is probably near the end where you can can watch Nick make out with Annie while his face is covered in the blood of her dead ex-boyfriend and some zombies.
During a cutscene in the prison camp, a soldier can be heard making the Wilhelm Scream, without a hint of irony.
Nausea Fuel: Everything about Darlene, from her appearance to her vomiting attack to her death, is just plain gross. Even worse in HD.
Porting Disaster: The PC version is crappily optimized, and is initially locked to 30 FPS (and the optimization is even worse if you unlock the framerate). On top of that, Super Ultra Dead Rising 3 Arcade Remix Hyper Edition EX plus Alpha isn't on PC.
Spiritual Licensee: An Affectionate Parody of an existing work?, wide open, objective-based stages with powerups?, a relatively simple combat system with light attacks, strong attacks, and supers?, the ability to mow down armies of enemies easily?, multiple playable characters?, multiplayer support? Are you sure Super Ultra Dead Rising 3' Arcade Remix Hyper Edition EX + α wasn't originally a Dynasty Warriors clone?
Vindicated by History: A mild example. When the game came out, it was criticized for a new creative team, and abandoning most of the satire and humor the franchise featured. After Dead Rising 4 released, which removed a number of features of the series, severely downplayed the freedom of what the player was allowed to do with items, recasting Frank West's voice actor, T.J. Rotolo, and once again changing creative teams (this time with none of them having worked on a Dead Rising game before), response to 3 has become somewhat better due to it trying to keep most of the franchise's core while still trying to do something new.
What Do You Mean, It's Not Political?: The situation with the "Illegals" is analogous to the illegal immigrant debate in the U.S. If the name isn't an obvious tip-off, Illegals are incorrectly blamed by the more Jerkass characters for the zombie problem plaguing the Los Angeles stand-in, and are used as a scapegoat by higher ups in the government. Furthermore, Nick Ramos, who is on the Illegals' side is a Central American immigrant.
