I was cruising around on TMP and came across a post in the forums about Dead Walk Again and thought I'd check out
http://www.pm-production.nu/index.php?file=kop1.php and to my surprise they are back online. The site has only limited info but it has a teaser regarding something called "Zombie Carnage". This was posted in May and there has been no activity since then.
Fingers crossed we see some more stuff soon.
