Can u perform a hidden fatality in arcade mode...

[reptile1523]

without first performing it in fatality trainer or unlocking it in the krypt?

probably. But with scorpion, as of now, you can only do toasty with his secondary. So you would need his secondary costume first.

i think you can, i tried them all in fatality trainer first just to see them and learn the distance...
