I'ma put my autism hat in the ring, the hud shown in forward unto dawn would honestly be the ideal. Compass, weapon layout/ammo read, small team positioning radar. I would take the borders out completely, make the compass fit the whole view instead of a small section and make weapon readouts just a number in the corner instead of showing the gun too. Basically perfect for general duties. Maybe add a small comms readout so you can see who's talking
