Space Hulk tactics can be brutal, and will punish almost all mistakes you make. If you are into the high tension and planning your turns carefully, it's a really good game and a faithful recreation of the board game (with some added mechanics for extra spice). This isn't Xcom. If you are not into the powerfist CBT experience and just looking for a 40K themed Xcom this is not the game you are looking for.

The only warning to give is that Online Multiplayer is dead so only custom missions and the two campaigns are left, which are the main attractions in my opinion.
