Supplies
Gathering a full set of supplies progresses towards Blood Bath multiball. Each individual supply also awards the following:
FIRST AID - Completing the drop targets when “FIRST AID” is lit will permanently increase the value of the prison yard walkers for the remainder of the game. In the Premium/LE, also awards a “Prison Bomb” which can be used to advance 1 hit towards Prison Multiball or collect a jackpot in Prison Multiball.
WEAPONS - lights the Arena ramp for crossbow mode. In the Premium/LE, also awards a “Horde Bomb” which can be used to kill a walker in Horde.
FOOD - increases a shot multiplier for the well. The multiplier is awarded for any hit to the well (letter, well, well multiball), then reset. In the Premium/LE, also awards a “Well Walker Bomb” which can be used to advance 1 hit towards Well Multiball or collect a jackpot in Well Multiball.
You can build up multiple walker bombs. The color of the button indicates which one is ready to go. Red is weapons, blue is first aid, green is food.
The main strategic use for the bombs is to have one or two in hand and have prison or well walker MB one shot away then you can play free and loose until you drain. Then simply hit lockdown button to start your MB. Also having the weapons bombs for horde spots your zombie kills so if you drain and are a shot away from the next wave, the bombs keep you alive.
