pattern in Super Hexagon and earlier versions of Open Hexagon involving two mirrored spirals. In Super Hexagon, it is featured in Hyper Hexagoner, Hexagonest and Hyper Hexagonest. In Open Hexagon, it previously appeared in every Level except Baby Steps and More Baby Steps, but it is now rarer, only appearing in harder Levels. It involves turning 360 degrees in the required direction (usually clockwise). Generally, only entering it is hard, as it can be completed simply by holding the required arrow key. However, it can make the subsequent pattern much harder, depending on its positioning.
In Open Hexagon's code, its label is pAltBarrage.
