And it's a free play weekend. You can pre-load it if you want to give it a try.

I bought it during the holiday, but my PC just can't handle it. I suspect this free weekend is going to have a lot of people finding out that they can't run it either.
If you're a regular, there's going to be a lot of easy kills this weekend.

I bought it during the release campaign in the hope of getting a mixture of Descent and UT only to realise that it ain't that and my PC can barely run it. At least it was cheap.
Edit: It was still sort of fun to play it a couple times though because controls are a bitch and almost everyone had the same problem as me with the controls. So everyone was floating around trying to hit someone without much success. :P

Posting here, if anyone is interested in watching it:
