Psi in Gurps?

[Orlando Glarion]

Hello

I wonder if there are any Psi-Abilities in Gurps.
For example, I want to play a warrior, not a mage,
but he should have one single Psi Power: He can read the mind of his
enemies!
Is this a normal advantage/disadvantage-thing, or is there a system for
Psi Powers?

Bye,
Orlando
