A modification of the kunos sf70h to use the halo head protection system, attachment is imperfect, but the main point is to experiment with this in VR, since you really shouldn't be using halo if you don't have VR (in a 2D screen you don't see depth, so you can't look around the halo).
Uses xdelta to patch the original kunos file, so it doesn't actually contain the original model.
