As Walmart stores opened their doors across the nation on Black Friday, thousands of shoppers infiltrated the giant retailer in a scene resembling a post-apocalyptic nightmare.

Some bared fists in the quest for a bargain, while others acted more nobly, rallying against the superstore in the fight for fair wages on the retailer’s busiest day of the year.

Gun fever was the hit theme of a new post-Thanksgiving tradition, with bargain hunters out in droves taking advantage of Walmart’s firearms discounts, a move that many activists have deemed irresponsible.

The nation’s largest gun seller came under fire today for aggressively marketing its firearms, going so far as to feature a Black Friday "Manager's Specials Sale" that promises 20 percent off select long rifles and shotguns at stores licensed to sell firearms, according to Huff Post.

Anti-firearm groups said gun lobbyists and the giant retailer were trying to capitalize on tragedies like Newton and other mass shootings by offering cheap firearms in a bid to revive sales, which slowed down earlier in the year. Others said the annual rush to stack up on guns was a result of fear that this year’s string of violence could trigger stricter gun-control legislation.

Adding to the commotion, thousands took to Twitter, Facebook and Youtube documenting shoppers going wild. One man was kicked out of Walmart by an employee for filming a fight in which a large man can be seen fighting with others over what appears to be a TV, as police stood by and did nothing.
