The Challenges Of Creating Metal Gear Rising’s “Blade Mode”

Takashi Wagatsuma, the programmer at PlatinumGames who programmed Metal Gear Rising’s Blade Mode feature (above), says he was given the following guidelines during the creation of the feature:

 

• Have a heavy focus on response, allowing the player to shred the enemy to pieces with their katana.
• Let the player be able to carefully adjust the positioning and angle at which they want to cut.
• Give enemies a weak point that, when cut by the player, gives the player a chance steal energy from the area they cut (a.k.a. “Zandatsu”).

 

While developing Blade Mode in line with these guidelines, a number of questions were raised by the development team, which caused heated debate among the team and a considerable amount of trial and error during development. Some of these were:

 

• How the left and right sticks should be used to control character movement, camera movement, and the angle and positioning of your katana.
• Should strikes in Blade Mode follow after the player’s motions, or should they be focused on camera direction?
• When entering Blade Mode, should the camera angle shift to where the player is facing, or to focus on the enemy? Or should it not shift at all?
• When the player uses Blade Mode to cut several things successively, in order to not overstrain the game’s system, what minimum amount of time do we need to allow between strikes?

 

Here’s the solution Platinum eventually settled on, Wagatsuma says:

 

The right stick in Blade Mode is used to rotate the angle at which Raiden will cut, while the left stick is used to adjust where Raiden is facing and the cut’s elevation. Using both sticks allows the player complete control over where to slice their sword.

 

Bringing the stick from the outside to the center (by releasing your hold) will cause Raiden to slice across the line appearing on the screen. Moving the stick in a direct line will cause Raiden to slice after a certain distance has been input; the □ and △ (X and Y for 360) will cause horizontal and vertical strikes, respectively.

 

When the player enters Blade Mode, we wanted our priorities to be on letting the player swiftly cut where they aim. To do this, we made sure the first strike in Blade Mode always follows the path displayed by the line on the player’s screen.

 

Furthermore, pushing down on the left stick while in Blade Mode will cause the camera to stay fixed in position and enable the player to move Raiden.
