For those of you that were hoping for another spring-powered blaster, too bad; the Hailfire is clearly flywheel-powered like the Nitron and Rayven. Although it has a capacity for 8 clips in its lazy susan of death, we're apparently only getting 4 and 24 darts, which means that it will come with 6 round clips. It's claiming a max capacity of 144 darts, which means that the drums most likely won't fit. Most interestingly, it says in the video that batteries won't be included, which means it's anyone's guess as to what powers this monstrosity.
