A stupid key that lets you unlock a giant robot that hates you. It’s the only thing that can stop Metal Gear Rex from stepping on your face.

I got the PAL key and unlocked Metal Gear Rex. He stepped on my face and I got a bruise.

The PAL key was useless. Metal Gear Rex just laughed and ate my sandwich.

I used the PAL key to fight Metal Gear Rex. He beat me and I got a broken nose.
