The most recent Helldivers 2 update brought significant changes to the game’s diverse arsenal of weapons, though not without some caveats. The Punisher Plasma now has a new interaction with the Shield generator of the explosive kind, and players are confused if it was added intentionally.
The SG-8P Punisher Plasma weapon can no longer be used correctly if you have the Shield generator equipped. Shooting the plasma with the Shield around you will cause it to ricochet back and explode, dealing significant damage, though not quite enough to kill you. This was previously not the case, and seems to have become an issue since Helldivers 2 Patch 01.000.300. The update introduced numerous changes to the game’s weapons and gameplay, and one tweak may have caused this strange interaction.
