Survival Mode is a game mode in 60 Seconds.
Unlike Apocalypse Mode, Survival Mode doesn't let Ted scavenge before the nuke drops. The harder the difficulty, the less supplies you get. On Little Boy, you may get all items and over 6 cans/bottles.
Amount of supplies given Edit
Little Boy = All/Many items
Fat Man = Average amount of items
Tsar Bomba = A few items/No items
