Quoted from Eskaybee:You must have clear the prison yard qualified to get prison bombs and ww spelled and running mb hit progression to qualify ww bombs. Once either of those are qualified, when all 3 drops are up the insert cycles between first aid, weapon, food. If you hit any drop when first aid is lit, it'll lock that insert and when you complete the rest of the drops you'll be awarded a prison walker bomb. If you lock weapon insert then finish the drops you get xbow award. And the food is for ww bombs.
Eh?
