SLA Industries (pronounced "slay") is a role-playing game first published in 1993 by Nightfall Games in Glasgow, Scotland. The game is set in a dystopian far-flung future in which the majority of the known universe is either owned or indirectly controlled by the eponymous corporation "SLA Industries" and incorporates themes from the cyberpunk, horror, and conspiracy genres.

The game combined concepts inspired by a range of aesthetics and ideas. Elements include: song lyrics from David Bowie and the Industrial music scene, cyberpunk fiction (including Blade Runner and Max Headroom), anime / manga (including Akira, Appleseed, Bubblegum Crisis, and Trigun), and the growing cultural obsession with the media (including 24-hour news services and the Gladiator TV Show).

SLA Industries itself is a fictional corporation run by a mysterious and seemingly immortal creature called "Mr. Slayer", whose upper management team includes two other creatures like himself, "Intruder" and "Senti". The corporation is headquartered in "Mort City", a densely populated city-sprawl larger than Eurasia and surrounded by the urban ruins of the "Cannibal Sectors". It is all located on a vast planet (also called "Mort") that had been stripped of its natural resources to the point that the ecology had been utterly destroyed. SLA Industries controlled an undefined but vast number of planets, collectively referred to as the World of Progress, and governed them in accordance with Mr. Slayer's Big Picture. The setting is bleak and surreal, with much left deliberately ill-defined in the source material.

Players take the role of freelance employees of SLA Industries, called Operatives, living in Mort City and taking care of odd jobs assigned to them by the corporation. These jobs usually involve keeping the peace—chasing serial killers, hunting monsters in the sewers, quashing riots, foiling terrorist plots, and silencing dissidents are common themes. Appearance, style and branding are emphasized in the game world as much as combat ability, due to the omnipresence of television; for ambitious Operatives public persona and TV ratings are often as important as professional abilities. A supplement, the Contract Directory, also provides the option for players to play as celebrity gladiators called Contract Killers. As a role-playing experience, the game tends to be predisposed towards splatterpunk horror, noir, dark satire, and/or gunbunny high action. However, the complexity and Byzantine politics of the setting allow for slower-paced campaigns based around subversion, inter-departmental rivalry, and cut-throat power struggles within the company.

Along with humans, playable races include the drug-addicted mutant humans called "Frothers", the stealthy feline "Wraith Raiders", the formidably violent saurian "Shaktar", and the two 'Ebb' / pseudo-magic using races: the emotionally sensitive and charismatic Ebon, and their more sadistic and violent evolution, the "Brain Wasters". There are also a variety of biogenetic vat-grown warrior races called Stormers, produced by SLA to fight in their endless wars.

SLA Industries was first published independently in 1993. The game was later bought by Wizards of the Coast late in 1994, after their success with Magic: The Gathering. It was later republished by Nightfall Games Ltd and distributed by Hogshead Publishing, until Hogshead Publishing closed down. Between 2003 and 2011 Cubicle 7 Entertainment produced new material, and in 2011 the license returned to Nightfall Games Ltd, who released supplements (known as Data Packets) as PDFs. In August, 2016, the Kickstarter for the SLA Industries: Cannibal Sector 1 miniatures game was launched by Daruma Productions and Nightfall Games. On 22 June 2018, Nightfall Games announced that Daruma Productions was entering the liquidation process and Nightfall would be taking over completion of the Kickstarter. Cannibal Sector 1, the last 1st Edition product was published in 2019.

A new Kickstarter campaign launched in September 2019, for SLA Industries 2nd Edition. It raised £90,444 from 1,281 backers. The KS also funded a new GM Screen Pack. Additionally, a free Quickstart was released in August 2019 to introduce the new rules, ahead of the Kickstart campaign. The pledge fulfilment started in December 2020, and the products went on general sale in January 2021.

A second Kickstarter was announced in July 2021 for the first sourcebooks for SLA Industries 2nd Edition to start on the 24th of August 2021. The first two books announced are Threat Analysis 1: Collateral and Species Guide 1: Shaktar/Wraithen.
