As far as game controls they can generally be learned from the game's tutorials but generally they are pretty much as follows, I might have missed some things, there is quiet a bit packed into the control scheme!

Thumbstick: Movement
D-Pad: Adjust Camera/Aim well holding L in Gun Mode
L: Tap to Center Camera behind you
Hold L: Locks on Target/Gun Mode active, well go into Aim Mode
R: Switch between Blade/Gun Modes
Hold R: Run
R+Circle: Shield Mode
Cross: Jump/ Double Jump/ Cancel on Menus
Circle: Dash with Blade/Roll with Gun/ Confirm on Menus
Square: Attack/Shoot
Triangle: Attack/Shoot
Hold Triangle: Charge up Predator Mode attack well on Blade mode active/Holding with Gun mode active to open up ammo inventory (Square: Use Item/ L & R: rotate between items)
Select: Item Inventory (Square: Use Item/ L & R: rotate between items)
R+Triangle

rar, here's some basic gameplay mechanics I've figured out, I honestly don't know everything, but this just just some basic stuff I thought might be helpful.

HP: Health Bar (Obviously)
OP: Not sure what it stands for, but OP is drained when you shoot in gun mode, but it's replenished by switching and attacking in blade mode, so juggling between the two is effective.
ST: Stamina Bar - Running, attacking, dashing and such will use this up a little, it replenishes fast when not being used, but using it all makes your character temperately stop for a breath.

Predator Mode: By scoring a successful nomnomnom in Predator mode, you'll recover some OP, but you'll also be charged up letting you access your blades special attack (a charging slash) or a special shot well in gun mode. Also well charged up from noming some god you dash faster, and gives you access to your double jump. Honestly I don't entirely understand all the benefits

Reviving Partners: When a character has fallen you can revive them at the cost of some HP, simply by holding circle well standing next to them.
