Valve has revealed that it will be adding more Achievements to games on Steam, starting with extra rewards for Team Fortress 2 in the coming weeks.
Word came from the company in an emailed response to a fan, who asked whether older titles like Day of Defeat: Source and Half-Life 2 would get the Live-style awards.
"We're planning on adding achievements to all of our games you touched on in your mail," replied Valve. "We're just now coming out of the post-shipping haze, so these should start showing up on Steam pretty quick here."
"We're also planning on adding a bunch more to TF2, starting with an achievement pack for the Medic in the next week or so."
Steam Achievements work in a similar way to their console counterparts. In games like Portal you can also bring up a menu to see what you've achieved so far in life. Just as well you can't do that in the real world, isn't it.
