Acetech's latest tracer unit and a multi-coloured one at that, the BiFrost, gets scrutinised by Hyperdouraku... "Introducing the ACETECH tracer, Bifrost with a video.
If you wear a tracer in a night game and shoot an air gun, you can enjoy it as if it were fireworks.

This bi-frost is a super fun rainbow-colored tracer that shines in 7 colors with a further evolution of the muzzle flash function!"
