Haswell Gen3 Devastator is a weapon in IronClaw's Just Cause X: Global eXchange series.


A first mass-produced assault rifle which uses caseless, magnetorheological ammunition, this model became a huge success for the Haswell company. After initial trials, huge contracts for buying this weapon were made with US and European militaries, as well as megacorporations like Black Hand. In 2020, the Devastator is very common (and feared) around the world.


It's a precise and very rapid-firing assault rifle, which is effective at extremely long, sniper-fire ranges. While not as powerful as Decimator, it can pierce through light armor, which is useful for killing vehicle crews and countering soldiers in powered armor (it can kill an AVIV X5 Raindance operator in one headshot).


  • It is made by Haswell company.
  • The rifle is based on real MRC prototype rifle.
