About Slitherine

Slitherine publishes turn-based and real-time wargames, grand strategy and tactical simulation, often with well known licences attached. Its range takes in Warhammer 40,000: Battlesector and Warhammer 40,000: Sanctus Reach, the Stargate: Timekeepers commando missions, Battlestar Galactica Deadlock fleet combat and Terminator: Dark Fate - Defiance.

The games come from a spread of specialist studios, including Black Lab Games, Proxy Studios, Flashback Games, VR Designs, Ageod and SoftWarWare, with releases spanning 2014 to 2025. Historical titles such as Decisive Campaigns: The Blitzkrieg from Warsaw to Paris, To End All Wars, Armored Brigade and Field of Glory: Empires sit next to speculative settings like Shadow Empire, ICBM and ICBM: Escalation.

Games in the catalogue

The listings lean heavily towards strategy and simulation, with action, RPG, co-op and indie entries mixed in. Broken Arrow and Headquarters: World War II handle modern and Second World War warfare, while Terminator: Dark Fate - Defiance and Stargate: Timekeepers bring licensed settings to the same tactical style.

Almost everything activates on Steam, and Warhammer 40,000: Battlesector also appears as a key for Xbox One. A large part of the range is made up of DLC and expansions, which add campaigns, factions and units to a base game you already own.

How buying works

Most Slitherine titles are sold as Steam keys, redeemed in the Steam client or website to add the game to your library; the Steam key activation guide walks through the steps. A few games, including Broken Arrow, Terminator: Dark Fate - Defiance, Headquarters: World War II, ICBM: Escalation and Stargate: Timekeepers, are also offered as accounts, which arrive with the game already on it and are signed into rather than redeemed.

Games are sold per region, and a key has to match the region of the account it is activated on, so check the region of a listing against your account before buying. Details of region locking are covered in the help centre.

Common questions

Which platform do these games activate on?
Almost all Slitherine listings activate on Steam for PC. Warhammer 40,000: Battlesector is also available as a key for Xbox One.
Will a key work in another country?
Only if the key matches the region of the account redeeming it. A key restricted to one region will not activate on an account registered elsewhere, so match the two before buying.
What is the difference between a key and an account?
A key is a code you redeem to add the game to your own library. An account comes with the game already on it, and you sign in to play instead of redeeming anything.
Do DLC and expansions need the base game?
Yes. Expansions and DLC for titles such as Warhammer 40,000: Battlesector or Field of Glory: Empires require the matching base game on the same account.
When do I receive my key or account details?
The key or account details are delivered to your order once payment completes.
