Well, you can't retaliate while they're shooting at you, so in effect you can only defend with the gun. Granted, you can fire the ammo back at them, but if they can probably get behind cover before you do damage. If an explosive is placed right, it can still kill you since explosions go through the shield. People can still melee you, and since the shots are very weak, you'd have to switch weapons if you wanted to survive, allowing them to shoot you down before you can get another weapon out. Like the other Conduit 2 weapons and perks that we've seen, the Aegis Device does have counters.
Anyway, I'm pretty sure that it has unlimited ammo but that its normal shot is very weak, as other people have said.
..... why is there so many of these topics??? these topics that dont even have to be made if people just LOOKED at the sticky!!! granted it does need to be updated, but even then, you can just look at the Conduit Wiki!!!!
