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.
