On the main title screen, enter the code Up, Up, Down, Down, Left, Right, Left, Right, O/B, X/A, Start to unlock Very Hard and Revengeance difficulties. Similarly, it will also have Raiden say the title of the game, similar to the Capcom survival horror series Resident Evil. This could be a nod to the fact that Platinum Games was founded by three Capcom employees, one of which was the creator of Resident Evil. In the PC version of the game, this will also unlock all downloadable content, cutscenes, Codec conversations, chapters, and boss battles.
Attempting to cut the cat wandering on the beach at the beginning of R-01 will result in it backflipping away from Raiden's sword.
Quickly cutting a hostage as he runs away will destroy his clothes. Codec the support team before the hostage vanishes to hear their reaction to Raiden's behavior.
The slash effect for the blade's "Quick Draw" charge move is more or less identical to Shuruba's charge-up move in Bayonetta.
Finishing a stealth section (ie, any which does not begin with Raiden already in combat) without being detected will usually result in the support team praising Raiden. In the Japanese garden in file R-04, completing the section will, bizarrely, cause Kevin to say "Yes, Tovarich!" in Boris' voice. Kevin will also do this if you stealth kill the Vodomerka in the sewers near the MiB.
Five Humanoid Dwarf Gekkos can be found, one in each mission other than R-00 and R-06. They will attack Raiden with very fast strikes or kicks, and if destroyed correctly each half of the Humanoid Dwarf Gekko will drop a Large Holo-Chip (+5000 BP), though these cannot be retrieved in file R-01 or R-04.
In R-03 and R-05, the buildings in Denver include the "Thunderbolt Cafe" and a large structure called the "Gideon Hotel," named after Sam Gideon, the protagonist of Platinum Games' Vanquish.
The Cat Comes Back
During the first-person sequence at the end of R-03, look right. Eventually a cat will walk in and the cyborg to the right will kneel, pet it and wave when it walks away.
The effect of suspended raindrops when using Blade Mode in the fight against Monsoon is virtually identical to activating Witch Time in a rainy stage in Bayonetta.
In the Japanese garden, after the first area, a guard can be found in a room with paper walls to the front and rear. Going behind him and getting a Zandatsu kill through the paper wall (his weak point will appear in Blade Mode) will earn Boris' approval.
Giving Sundowner a proper funeral
After defeating Sundowner during a replay, in the limited time before the first Codec call, the player can use the pincer blades to knock Sundowner's remains off the ledge.
Pin up posters are located in the following locations:
R-03: Mile High
- At the beginning, on a wall to the right, covered with police tape.
- The cardboard prop in the upstairs lobby after the fight with two Grads can be cut to reveal another figure.
- At the long staircase, prior to Samuel Rodrigues' speech.
R-04: Hostile Takeover
In the 20th floor.
In R-03: Mile High after entering the first building, there are a pair of World Marshal vending machines there that, when cut, drops an Electrolyte Pack each. Another pair of these vending machines are found in R-04: Hostile Takeover right next to the door that needs to be opened by destroying three electrical panels.
Go Ninja, Go Ninja, Go!
During file R-02 Shortly before Raiden fights the Raptors, George will say "A ninja? Cowabunga! Go Ninja, go ninja, go!" and after the fight he will ask Raiden if he "lost his map to his ninja hideout." This is a reference to the Teenage Mutant Ninja Turtles 2 club fight scene.
