Powerguy does have their rules correct though; the do 12" move, Shoot and a 2d6" (exact, not up to) jump in a chosen direction, that could result in loss of models due to doubles(they still move though) or landing in impassable terrain in the assault phase, instead of assaulting. They can also assault as normal(up to a 6" walk)
Everything with them is spelled out in the Eldar Codex, page 36.
Second jump move is "up to
2D6" " if you read it again
Also remember that jump and jet infantry are allowed to walk, if they so please (such as avoiding dangerous terrain rolls), unless their codex specifically prevents them. The jump move is actually not the default move.
