very easy with necromancer, spawn skelletons and let them do the job. even eggs or final boss. magic missile bounces off walls and very short cooldown, nice assist for runtrough. and finally heal.
no controlls pre-configuered, butr if u know how to use the special weapons, its okay to kill the 2 bosses. i thought the alien one was the endboss...
there are 15 levels, pretty funny to nuke the last boss down in about 15 seconds xD still cause of the hard start 3/5
