I think they shut down the website for good. Because every time I go to http://criticalstrikeportable.com/ it takes me to C-Ops on facebook so I think they shut it down for good but if you still want to play it then go to here http://www.mediafire.com/file/hwfiffgvvzc3fc3/csp.rar download it and download WinRAR http://www.rarlab.com/download.htm and get it and extract the Critical Strike file and Play Multiplayer and Singleplayer. If you need help doing this then watch this video. https://www.youtube.com/watch?v=PpxT0_mnt7s
