Psionics is now called VooDoo because it's in the future and pirates aren't very smart and it looks like magic! Anyhow, keep in mind hands are not as resilient as vanilla X-Com soldiers, nor will they ever become capable of walking Psi Gods as Psi-Amps are no longer equipment to carried, but VooDoo-amplifying armor must be worn instead. In addition, VooDoo Skill and Strength are not as high as vanilla X-Com soldier values.

why? :
+ hellerium
(Ellerium-115++) - lets suggest, imagine theory, about how existence of super-heavy, stabile elements, got (mostly positive) "mutantive", mutating effects on common human race, --===> origin, genesis of *Uber"
( +and direct implementing, using those super-heavy element into fyziology of this new stabile, mutant sub-race, *Uber-strain" --===>
-----> origin, "activation´, and amplification, strengthening - also psionics gifts, telepatics skills (until creation of mutant Uber-strain amybe no-existent, -but, more probable, more ..fitting, - until rise of mutant uber -strain, those psionics skills were just, genetically, recessive, dormant genes... - until woked-up by mutations, by sub influencies superheavy Hellerium element
