Call of Duty: Black Ops 3 multiplayer, via the PC only Starter Pack, is available free to all Steam users this weekend.

The Black Ops 3 'Multiplayer Starter Pack' offers access to the game's multiplayer mode, including the full collection of maps and public ranked multiplayer matches, but with a handful of restrictions, including the inability to Prestige or play in custom games.

You won't be able to access the Campaign, Zombies or Nightmares modes, either, so if you want to play those you'll need to upgrade to the full game.

Call of Duty: Black Ops 3 base, digital deluxe and Upgrade to Full Game, are all discounted on Steam until Monday.
