To celebrate its collaboration with Digital Reality on Sine Mora, Grasshopper Manufacture printed up some shirts. To celebrate the fact that Grasshopper's handling the sound for the new downloadable shooter, the developer is giving those shirts away in exchange for shooter sounds ... made with your voice.
"We want YOU to recreate the sounds from your favorite shooters!" the contest announcement explains. "This can be sound effects, background music, voice overs, explosions, whatever! As long as you're making the sounds with YOUR voice, it's fair game. Skill with music editors isn't required - we want to hear your soul!" We hope Grasshopper is prepared for the rush of amateur Star Soldier singalongs.
