Silent but Deadly is a good model to use when trying to dispose of the Walking Dead. The problem becomes that; chances are the quieter your weapon, the closer you have to be. One good alternative is to use old fashioned projectile weapons like Crossbows and Longbows. Unfortunately, Longbows require a lot a skill, and the time it takes to load and cock your Crossbow could spell death.
Thank the people at Swiss Crossbow Makers for the Twinbow II. The innovative cocking system takes about 3 seconds after firing, which in Crossbow terms is lightening fast. It’s easy enough for just about anyone to do too, “whether physically challenged, young or old, women or men“. Don’t think you’re sacrificing any power or precision either: This sucker shoots at up to 370 FpS and is impossible to cock off center. Oh yeah, it’s also doesn’t hurt that it’s Swiss made; if the quality is anything like their Watches and Knives, you know it’s good.

You can check out some cool videos of the 3 second cocking action here and here. They’re totally worth a watch.
