Valve is giving away access to online multiplayer Modern Warfare 2 on PC for free via its Steam download service.
However, the deal only lasts until Sunday - so you'll have to be quick if you fancy some weekend war.
The multiplayer access will kick off tomorrow at 4pm PDT - 11pm to UK readers.
Enjoy yourselves. Or just go on there and moan about the lack of dedicated servers.
