Serious Sam Wiki

The Serious Bomb is a handheld explosive that is featured in many Serious Sam games. It happens to be the main logo when referring to the Serious Sam series, appearing most famously on Serious Sam's shirt in virtually all of its appearances.


When the fire key is pressed, the serious bomb will take a few seconds to warm up, and then it will explode, killing every non-boss enemy within a 750 meter (in-game) radius of the player.

How the player uses it depends on the game; in The Second Encounter, the player simply needs to hit the "0" key to start the timer. In other games, the player must take out the serious bomb, then hit the fire key in order to start the countdown. In Serious Sam: Double D: XXL, the serious bomb is launched from a serious bomb launcher; the launcher has to be fully charged to be able to release the bomb.

The serious bomb is absent from Serious Sam 3: BFE, Serious Sam 3 VR: BFE, and Serious Sam 4, being replaced by the C-4 Demolition Charge and Mini-Nuke instead.

Serious bombs are rare weapons and the player can only carry a limited number of them, thus they should be used sparingly and only as a last resort if the player is absolutely overwhelmed by enemies. They often appear before a big fight begins so that the player can stand a chance, should they be unable to fight a large horde of enemies at once.


In The Second Encounter, the first serious bomb appears in Valley of the Jaguar, while another one can be found behind a house near the 'bloodbath secret' in The City of the Gods. A few bombs also appear in The Pit. In later levels, serious bombs usually appear before a big fight begins.

In Serious Sam: Double D: XXL, the serious bomb can be acquired by by purchasing the Serious Bomb upgrade from The Trader using Cerebral Controllers. It is an upgrade for the LM32 Rocket Launcher and is unlocked after completing the game for the first time.

In Serious Sam: Tormental, the player can acquire a serious bomb by purchasing it from shops with keys. It also has a chance to appear from a blue Mental chest or after clearing a room full of enemies.


Serious Sam 1[]

  • Ideally, the serious bomb should only be used if the player has to deal with too many enemies and has too little health/ammo to counter them without reloading saves many times. However, experienced players may use it to quickly kill any group of enemies even when not really necessary, if their serious bomb capacity is full and they know there's another serious bomb coming up soon - letting it just go would be a big loss because of how rare they are.
  • The serious bomb is also useful against hordes of strong enemies, such as Kleer Skeletons and Sirian Werebulls. This makes hordes of strong enemies extremely easy to deal with, which is very useful no matter how much health/armor/ammo the player has.
  • In tremendously wide areas, the serious bomb may actually not be able to kill every single enemy in the area. One example is the boss fight against Kukulkán, where depending on the player's position, the Fiendian Reptiloid Demons perched atop corners of the surrounding walls may not die from the bomb if they're too far away.

  • With the serious bomb, the player should make sure they're in a somewhat safe position before they take out the serious bomb, as they'll be vulnerable for several seconds while the bomb's countdown animation is active.

Serious Sam: Tormental[]

  • The serious bomb is very useful for clearing out rooms full of enemies, especially after completing a loop.
  • It is especially useful against the ghost enemies in Nightmare Caves, as the latter can only be killed with explosions.
  • Bosses such as the Arachnithid Matriarch and Brainstorm can take a lot of damage from this weapon. The more bombs the player has, the easier it is to defeat them.
