AI kicks in straight after order is given and achieved. Makes controlling the robots tedious at best. Very poor game, first two badges are easy but the bad AI makes the challenging difficult.
ALWAYS buy the extra elevator when it's offered to you, buy normal $100 turret and 2x$400 machine guns for each elevator as the money becomes available. Once you get past Day 4 start replacing $100 turrets with $4000 ground hitters, once all elevators have 2x$400 and 1x$4000, sell one $400 gun on each elevator and replace with $1000 pusher-backer. ONLY upgrade the $4000 ground hitter, keep elevators as evenly powered as possible. Once money starts really piling in, sell $400's on all levels and replace with $4000's. Upgrade as you will and you won't get touched once through the whole game :)
