Undefined Ception

Undefined ception is one of New AC's that exist in game

Technical
Undefined Ception is different from the General Arena Closer, with one auto turret on top. The auto turret can fire to places other than the Undefined Ception is facing, making it much more efficient than the original Arena Closer. This can also mean it can kill players twice as fast. Otherwise, it is a normal arena closer, with their fast speed, even faster bullet speed and their signature one shot, one kill bullets.

Design
That looks like Basiception and Arena Closerception
