Garry’s Mod is a sandbox mod for the Source Engine. Unlike normal games there aren't any predefined aims or goals. Players are given tools and are left to entertain themselves. The player is in a world where objects can be created and destroyed on demand. Where people can be created and destroyed with the click of a mouse. A world made for him. A world he made.
Basically what I did in this pose is that I experimented with using lightbulbs to make muzzle flashes and messed around with bloom settings.
Looks better than your usuals
