It is possible the repair shield generators from underground. Was an AMP station. I think he was in the tunnels with the moving lines underground. I heared numerous explosions followed by the repair sound until the generator was repaired fully again. When i told this in yell the enemy was quick to point out we could just use a bug/method with the NS22 weapon and a underbarrel grenade launcher attachement to prevent it. Why do I need to use some abstract method to stop someone from clearly exploiting the game mechanics? Or is this just "clever" play and everyone is free to do it?
