If you're based in the UK and you have a penchant for video game cosplay, then chances are you'll be familiar with the sterling work of Landstalker Props. Landstalker has been producing accurate replicas of video game weapons for ages, and has tackled such projects as the gun from Portal and the plasma cutter from Dead Space 2. Needless to say, the results are amazing.
In fact, they are so amazing that Landstalker was recently commissioned by Ubisoft to replicate Edward Kenway's flintlock pistol from the forthcoming Assassin's Creed IV Black Flag. As you can see from the images below, it's pretty darn impressive — sadly, it's a one-off piece and won't be for sale, ever.
