I think the game is great just the way it is. Health packs are fine and ammo is good. Game could use a tutorial and a menu displaying all of the commands. The sensitivity option needs a label. Needs more weapons like Halo. Armor is good. Weapon switching should be as Q & E. Inventory as Tab. Add grenades and make them as G. I liked this game and it's reminds me of Halo: Combat Evolved.
