The RB-45 Hand Grenade is a weapon in Serious Sam 2.


The RB-45 is a hand grenade that can be thrown at any time by pressing the alternate fire key.

Mechanically, the RB-45 is exactly the same as a grenade fired by the MK 4 Grenade Launcher, which means the grenade will either explode after hitting an enemy, or three seconds after it is thrown. However, it cannot be charged up and its speed is similar to that of an uncharged MK 4 grenade.


  • When using the Hand Grenade, the player should remember that they need to get in somewhat close to an enemy because of the grenade's short range.
  • The Hand Grenade is an excellent weapon to use against groups of weak enemies, such as Kleer Skeletons. A single grenade can completely destroy a group of weak enemies, and significantly thin out a larger one.
  • The Grenade is also an excellent “follow up” weapon to quickly add extra damage to an attack. Simply fire the grenade directly at a foe while firing at it with another weapon.
  • If the player misses, the Hand Grenade can still do damage via splash damage.
