Ooooo im sooweee i raised my typing voice, we should both go on ricky lake and talk it out. Immersion has nothing to do with ammo. You basically already have unlimited ammo in the game if you include ammo reset and ammo synths. Having to go into your inventory to add more ammo takes away from the immersion because youre adding an unnecessary break in the game play. Having to run around a corner and take a break to regen ammo while you grab a soda or smoke a cig adds another break into gameplay. If anything weapons like ice breaker invective and black hammer add to the immersion because you can concentrate on killing shit (primary focus of the game) and not on going into your menu to magically get more ammo.
