Time Bomb



Time Bomb is mentioned in Metroid and Super Metroid, but not in the former's remake. After defeating Mother Brain, Samus will be given a message that the Time Bomb has been set and that she has 999 seconds (Metroid) or 3 minutes (Super Metroid) to escape. In Metroid, she only has to escape Tourian, but Super Metroid leads to the entire decimation of Zebes.
