Over the weekend, PC games all over the globe have enjoyed the two new Batman: Arkham Asylum maps offered for free by Eidos and released via the Games for Windows Live Marketplace. If you weren't able to download the free downloadable content pack (there were some problems, indeed), head over to the GfW website now and start the download.The free Batman: Arkham Asylum DLC adds two new Challenge maps and you can play them as soon as you get them. It’s a really nice gift from the developers of one of the best selling games of the year who got the number one position in the Steam sales report.
