You cant get it now. It was rocket league sideswap promotion 4 months ago. There was a challenge through which you could get untradeable WOW explosion and MTRX: INVERTED.

Didn't realize it was a limited time thing. Glad I played Sideswipe at the time. Haven't really touched it since then though. The amount of people on there with epic skill makes the game impossible to enjoy. I'd rather be stuck trying to rank up in RL.
