the way the mechs are set up... just not a good idea.
maybe on a different game engine, but not crysis' Cockpits move with the mech's animations. To have them anywhere stable enough to not drive everyone sick with motion sickness, you'd have to scale back the animations, which would make mechs move really unnaturally. Not to mention require an entire redo of the animations. on top of that, many mechs have very wildly differing amounts of cockpit space, meaning each mech would need to have its GUI individually designed ( like the difference between a mauler cockpit vs a Scat's), which for a mod team is a logistics nightmare.
naw, HUDs gotta stay projected at least as far as i can tell
