Shields aren't a problem. Just practice getting on the target's tail and keep hammering from short distance. Don't use torpedoes from far out but as a sledge hammer into their rears when you're only 20 or less units away.

You just need to fire a few more times.

Shield's arn't a problem anyway. Just use Tachyon Cannons and ignore them to your hearts content.
