I beat that stage thanks to Chill Cat (True form of Wheel Cat). I just kept spamming him and stacking him, and eventually, he went down. Try and find out which units have anti-alien abilities, and level them up. I agree with Ethanlac to a certain degree, but Jailbreak Tunnel is very far into the Stories Of Legend. So unless you have that sort of patience, I suggest that you go for all of the anti-alien treasures.
