I'm confused by how the adrenaline shield thing work, it says killing an enemy recharges the adrenaline shield power, but the actually shield is called something ells... Any ideas on what this is and how it works compared to the default shield?
You need to equip it instead of the default HA shield. [it will show up in your loadout once you cert it] It works similarly to that one, but instead it can be replenished by kills according to your certs. I used it during beta and it was pretty effective, I like it better to go all out and sometimes get some impressive streaks. Compared to just abusing the normal shield and being 24/7.
