Alan Wake - The Signal DLC. Worth buying?

I'm playing through Alan Wake atm and really enjoying it. Think it's gonna be a game I try to max. I've heard that the ending doesn't really answer much, but is apparently answered in both lots of DLC. Has anyone played through 'The Signal' yet and is it worth buying?

Think someone gave me a code for the signal off this site played it for about 30mins and i got bored.
All i seemed to do was aim torch at words got a bit dull

It's well worth buying in my opinion, adds another 2/3 hours of gameplay and answers some questions, not all of them though!

I don't know how much it costs, got mine free with the game, but if you're an Alan Wake fan I'd buy it.

I think it's 560 points. Was thinking of buying some next week because the 2nd dlc is out then too.

Still need to play The Signal. Better do it soon with the new chapter coming.

ive got 1250 gs on alan wake, my favourite game this year. i got a free signal code with the game. the signals worth 250gs. the cheevos are pretty simple, find the collectables etc, the only one is complete in one run thru with no deaths or continues,thats quite difficult cause at the end you get attacked by eveything. i think its def worth buying
