There should be like an armored monster carrier that shoots fireballs like teratorn does and drops the monsters out to let them attack the tower next to them then they get back in a go to the next tower. It should also have like an EMP burst to knock out mines next to it. You also have to put the monsters you want in it at your base before you attack
