Priced at around L15, Killing Floor is just about worth its weight. The extra content and support provided by Tripwire, as well as the modding community will help add extra value to that. Those of you who are happy with L4D might enjoy a change of pace with this title, then again you may not. There really is very 'little' to this game in terms of depth, and it still feels a little bit like a mod. Play or not, it's still a decent little title, and a testament to just how far you can take your hobby if you but try.
