Short and I had lots of issues getting the game to run, but once you are playing it's a good story driven 3rd person shooter that's very immersive and fun. Also had quite a few things I haven't seen in other similar games that fit well with the setting/mood of the game. There are also some very nice looking levels, in particular the ones in the office building near the end. It is short though, I finished the single player in just 4 hours but if you see it cheap it's worth checking out.

Pretty fun game, but has a lot of issues due to the port, in particular the terrible default controls and the fact that no matter what you change them to all the quick time events will always show the default key which for me meant seeing 'Q' pop up when I actually needed to press 'F' which made the quick time events a real pain. Also the targeting and the locked cameras for many boss fights are really frustrating as they do not work well with keyboard and mouse. But issues asside it was still mostly fun :).

Quite a fun 1st/3rd person tower defense game with persistant RPG elements like level ups and random items. Quite addictive too and has good support for co-op play online and even locally.
