Larger And Just As Annoying
The Queen Leaper is the Primarch version of the Leaper and they are a lot bigger than their counter-part. They only appear in the Co-Operative Campaign and when found, it will be quite apparent just how large they are. They only appear during the Bryce Canyon and Chicago levels and are usually accompanied by a swarm of Leapers.
Despite their size they are extremely fast and deadly. As with all Leapers they also possess the ability to leap at their opponent and this can be quite deadly if a player gets hit.
Taking one down however, isn't quite as awkward as the other command units. Keeping distance and strafing around can keep a player quite healthy and as long as the minions are dealt with effectively, the Queen Leaper shouldn't pose much of a challenge.
