A simulation tactical shooter that is broken by so many things that makes it so frustrating.
Sometimes, you will have to run several hundred of meters before hitting a checkpoint, and then, if you fail, you will have to run again this distance before having a chance to retry your objective. That makes the game so annoying. If you have the ambition of trying the hardest difficulty level, prepare yourself mentally at redoing several 30 minutes play without having any save. Be sure to understand your objective before going anywhere.
Your squadmates are so stupid, you will have to kill almost every enemies yourself, heal them when they are down, etc...
There are absolutely no video throughout the game. You will see the objective at the beginning of the missions, but nothing more.
You will probably have more fun playing Ghost Recon or Rainbow Six than this.
