This became one of my recent faves. If you can: Play the 360-version on a newer Xbox-Console. It works so much better than the weird PC-Port.

Condemned is a gem of gritty crime-stories, which just turns absolutely crazy in the end and MY GOD... the shopping mall haunts me till this day. Those freaking mannequins...
I love the grounded approach on the investigation and the fighting is also damn fun. Monolith are really a hidden champion when it comes to their games!
