As long as it's not like in BF2. I didn't like the tick ammo counter and I didn't like the huge enemy health bar. RC style might get too messy and resource stealing, and what about rebels who don't have implants?
The first thing is to make 1st person smoother a la Halo, Half Life, COD or most quality FPSs. In depth HUD is useless if I feel like a tank
