"The M1A1 Thompson capable of bringing flashbacks from the previous R2D game."


The M1A1 Thompson is great at tearing down hordes and having the ability to continuously fire for a while without having to reload. Having somewhat decent accuracy, good damage and being automatic makes this gun a great pick-up for any survivor. Be careful, for it does chew through ammo pretty quick, so try not to miss too many shots.

If you like having the ability to kill multiple targets without having to reload, then this is the weapon for you.

Background Story

During the more pre-modern times of the apocalypse, it was clear to R-Brain Hardwork that there was a distinct lack of fully-automatic weapons. Yes, you can make cases for the M134 Minigun and the Skorpion, but they weren't what the masses wanted. The Minigun had a limited ammo supply and the Skorpion was an SMG that shredded magazines. The company in question had managed to salvage old blueprints pertaining to the times of tragedious war and saw potential in it.

The M1A1 Thompson was reborn that very day. When the time came to ship it out to the market, they were worried that the people wouldn't approve the changes made to the historical gun; making changes to its magazine size in favour of higher calibre bullets and reducing its rate of fire. But they were proven wrong that day. The positive reception the Thompson received that day was tremendously motivating. Those adjustments made the gun much easier to control. The reduced recoil and the solid time to kill was enough to push it towards a healthy position in the gun market. Without this, weapons such as the AK-47 and the HK416 would have never seen the light of day.


  • The fire rate can be slow, so aim at the head to be efficient.
    • Take advantage of the firerate, you won't instantly chew through ammo.
  • Don't bother tap firing. It's the same thing as going fully automatic.
  • While ADS'ing, mind the recoil. Pull down to compensate.
  • You can bring armor, such as the Bulldozer I or the Bulldozer II, and you will have 3 mags, which will make the gun's ammo last longer.
    • You can also buy the Drum Mag to have 15 additional ammo, but it will decrease accuracy slightly.
      • This can be compensated with crouching and ADS'ing..
      • It's recommended to buy this attachment, so long you do not care about accuracy or shooting from long ranges.
  • Use the Ironsights attachment, which is supplied on purchase, as it makes the gun slightly more accurate.
    • It can compensate for the accuracy reduction of the Drum Mag.
  • This gun can be considered a slower version of the AK-47.
    • This weapon is better than the AK-47 on Boss rounds because of its higher ammo capacity with the Drum Mag attachment and higher total damage compared with the AK-47.
