This is a commission for a friend (Not on DA to my knowledge) who is developing a science fiction video game over in Poland.
His game universe employs three main types of weapons, plasma, gauss, and EMP.
These are three of the pistol class weapons for the game.
Top- The Olympus Armaments PL-709 Distressor Plasma Pistol with under-barrel laser targeting guide
Middle- Taurus Armory Stackmag Classic 50. Gauss pistol with Smartscope attachment
Bottom- Veritas Developments ZLX-7 EMP Compact with auto-flip Holoscope attachment
