Team Fortress had a major revision recently, one of those having new weapons that are only unlockable once one succeeds in getting a number of achievements (think, challenges).
Several hours ago, some people discovered that a certain in-game command allows you to unlock select or all achievements, therefore unlocking the new weapons as well. So the thing is, is this right? is it ok? Will it result to a ban?
To the curious: Yes, I placed the command here as well, but it no longer works for TF2. You can use them for Portal and Episode Two though.
