How do you deal with the Sentinels in Arc Raiders?

they don't move, so the whole fight is about line of sight. when the laser lands on you it's already tracking, so don't stand there trading shots in the open - drop behind something solid and wait for it to lose you. approach from the side using cover and only peek when you're ready to dump a full mag into it. if you're not getting anything from that spot, skip it. a lot of the time it's just guarding a route you can walk round.
