yup. move levin FAR to the right, then use the halberdier guy and a secutor to plug the two-hex gap between you and the pursuit forces on the far left. have clarissa, labyrinthia, and an elementalist all equipped with elementalist oc skills, and move them next to the fallen pillar. have clarissa kill the guy next to her in the middle using her gun, and then drop vortex/fire on the guys on the other side of the pillar (topmost two are weak to vortex, bottom one is weak to fire -- you should one-shot them). levin should be able to defeat the excavator that will chase him by ticking away at him with blast, and when you've wiped out the folks on levin's side, help halberdier guy and your secutor mop up the last of the pursuit forces. pretty easy map compared to the next one!
CHECK ENEMY ELEMENTAL WEAKNESSES! if felius and the secutor are getting raperaped, send an elementalist to assist. also, have felius/secutor equipped with a gadgeteer skillset.
