It was almost game over in Grande Prairie this week for a cosplay enthusiast.

Dressed as a character from Fallout, a popular post-apocalyptic video game series, the man walked down a street wearing a gas mask, helmet, armour and bullet belt.

RCMP Cpl. Shawn Graham told CBC News that police received calls just before 5 p.m. Tuesday from citizens concerned the man was wearing what looked like a bomb on his back.

At least eight officers responded with their long guns drawn. Photos show them crouched behind vehicles and bushes.

"He was observed going into a business, so the RCMP members were able to safely remove the staff members from the business," Graham said.

The business was Lynn's Alterations at Bell Tower Plaza. The owner, Hoa Huynh, said the man wanted some alterations to the costume.

He says police then told him to leave out the back door. He did.

Graham said RCMP soon made contact with the costumed man.

"Through conversation with the male they were able to determine that he was wearing a costume and there was no threat to the public," he said.

What had looked like a bomb turned out to be several Pringles potato chips cans that were painted silver.

The man was taken into custody but later released without any charges.

Photos appear to show officers smiling and laughing after the incident was resolved.

"In the end you've got a good feeling after going, 'OK, there wasn't a bomb, there was no intent to do anything criminal, it's just someone with their costume.'"

Graham thinks it should serve as a warning to others who enjoy cosplay that police will assume fake weapons are real.

"There's a time and a place for it," he said, pointing out that costumes are OK at conventions and similar events.

"Wandering around downtown [is] maybe not the place to do it."
