The Lesion we know and love in Rainbow Six Siege uses Gu Mines to deter attackers – these are those lovely invisible devices that fire poison syringes that cause damage over time, screw with your vision, and prevent you from sprinting until you’ve pulled them out. But Lesion’s gadget began as a different and much more painful-looking trap.

Concept art displayed at the Six Invitational in Montreal shows various early designs for Lesion’s trap, and variations of his character icon indicate several different ideas for how he might have operated if the team hadn’t eventually decided on the Gu Mine. One diagram shows a folding spike trap, which can be unhinged from a carry mode to deploy two rows of nasty-looking teeth on the floor.

There’s nothing particularly high-tech about it, other than perhaps the lightweight materials in the frame designed for portability. And it’s clear the Siege team decided to move forward with a more complex device for Lesion – another piece of concept art shows variations on a mine-like device with a penetrating spike on the top and three fold-out feet arrayed around the base.
