His big blue rival shown in that pic did OK, it shot fast, but the smaller ones he brought (linked below) hit harderRIVAL, YESSSSSSsssss. Love the Rival line!
I love the Rival Hypnos, so much fun. Oh, and the Nemesis, man the Nemesis is awesome.
BUT none of them compared to my MK3, that thing stings. I accidentally shot my buddy right between the eyes with it lol. Oh and bonus points because the darts that mine shoots hit something then fall, whereas the balls ricochet 10 times then get lost forever.
