Ok, so this one is really interesting. I found it yesterday and played it till 4:00 am this morning. Its great combination of tower defense and steampunk fps shooter. It has a free demo so i recommend you to try it out...beware it gets really intense on higher difficulties. The full game is also really cheap like 6 bucks.
As a most coop game played with strangers it lacks true cooperation, and this game really needs cooperation to not get owned. So its better to play with friends.
..and btw its one of those games where loosing is fun!
