Upgrade stacking

[Yamu]

I'm just curious. I have the Enhanced Bio Suit, if I learn Spititken do the to increases stack, or since i already have a x20 powerup it would do me no good?

I hate to sound like a power-gamer I'm just wondering.

No, you can't stack. Things are being discussed to possibly change this, but for now, you can only go to what your highest power-up is
