My first job in the industry was at the now defunct system-x. I designed about half the NME product line (pads, clothing, etc.), including the NME marker. I only stayed there a year, but since I've done:
MARKERS:
Engineering for the FEP quest (was my project at system-x, and was "taken" by another employee after I quit, who then started FEP)
Infinity legend, HK legend, and one more version they have not released yet
Alien Independence, remains(2nd version....don't know if jack actually made this one)
currently engineering my own marker for one of the mid-level companies....just got the first prototype in, so hopefully I can tell you what it is in about a year....maybe debut at HB next March.
Other stuff:
pretty much everything that critical paintball makes
various projects for SLY, including the new Profit goggle system (the ear muffs aren't my fault!!!)
thats off the top of my head
