The Thompson Submachine Gun is a weapon in Serious Sam: Double D.


The Thompson Submachine Gun is an automatic weapon that fires bullets. The bullets do a decent amount of damage and quickly hit targets. It also has a large ammo reserve, allowing it to be used for extended periods of time.

The golden version of this weapon increases the bullet size and damage.


  • The Thompson is an excellent jack-of-all-trades weapon. It does a good amount of damage and has a consistent and good rate of fire. This makes it a great weapon to use with nearly any gunstack combination as either the main focus or as a supplement weapon for more powerful ones.
  • The XL4 Lasergun works very well when paired with the Thomspon. Both are rapid-fire weapons and their combined fire can quickly cut down weak or medium-strength enemies.
  • Another weapon that works well with the Thompson is the MadDog Grenade Launcher. The Thompson is useful for dealing extra damage on a target while charging up the Grenade's Launcher.
  • Ammo for this weapon is common, making completely running out of ammo not a major issue for the player.
