Cold Winter is a 2005 first-person shooter video game developed by Swordfish Studios and published by Vivendi Universal Games for the PlayStation 2. Its story was written by Warren Ellis.

The game uses the Karma Physics engine, allowing for interactivity with items in the game world and for ragdoll effects. Cover can also be improvised by using objects in the environment; for example, the player can flip a table to provide cover or grab a table and block a door. Over 30 weapons are available.

The game offers a multiplayer component that supports up to four players offline and eight players online; in the offline mode, human players may be substituted for CPU-controlled. There are a dozen maps and six modes, including deathmatch and king of the hill.
