This came out of left field. Awesome though, because that means we're one step closer to getting Ikari Warriors II: Victory Road. I thought it was the coolest thing in the world when I was a kid when my folks would give me 4 quarters, so I could play it at the local video store.
I don't understand why they just didn't do what they did with Heavy Barrel on their Wii collection. That game also used a LS30 stick in the arcade, so they allowed people to aim with the right stick when using a GCN or Classic controller.
Why not allow the 4 face buttons of the PSP handle aiming, like something such as Robotron 2084 would've been configured on a SuperNes controller, for instance, in the pre dual analog days?
And go a step further and map your primary fire button to those same buttons, with autofire enabled so when you're aiming, you're also firing. Making you still have to hit a seperate button just to fire your primary weapons detracted a bit from how Heavy Barrel played on the Wii, even if it was accurate to the arcade game, but we also don't have a LS30 stick at home to use with these things.
The only fire button that is needed is for your secondary weapons to release a grenade.
That's how they should've did it. Instead we have this nonsense with the shoulder buttons to put up with.
