Just Cause 2 wingsuit(Or superman)
Title says it all
Velocity and handling are still very close to the parachute, although you have a bit more control because there's no other entities strapped to your back.
Original idea by flyboy95 of the facepunch forums and ICdevil.
Put the x_jj_wingsuit.arc/tab in your justcause2/archives_win32 folder.
UPDATED: Grapple hook is fixed
UPDATED: With thrusters(Thanks to powerslave212 for the dlc help):
NOTE: I just want to make it clear that I am only endorsing powerslave's version of the mod, not claiming it for a prize.
