try lodes of the drones/noobturrets with upgrades... i find it hard not to stay in full iridum... even when thay get though the my defence (yes my defence of noob turrets)
so the ghosts can walk though walls... but thay cant get over the mear hole in the floor... so if u r scered of ghosts just dig a lode of holes around the house
what i dont get is why dose it go attack--> defence-->RANGE-->MAGIC
i meen shouldant range come 1st and then maybe magic
(coz u r prob not guna start close range and then get to long range)
Nooo, it's randomly generated :)
