The game succeeds, I fail at playing it!
Its a weird game that plays great solo and the games play out very much like Space Hulk Proper games do 85% of the time: The Marines start strong, they have enough firepower and people to position themselves at the right places most of the time. They move through the hulk smoothly, and then something happens to slow things down. Maybe there are 5 corridors that need covering but only three marines to do so, or maybe one marine has found himself trailing behind, whatever the cause the end result is the same - DISASTER.
One marine croaks, then the rest are vulnerable. Then another, and by that time the house of cards that is the mission is about ready to fall the eff down.
So far my first two missions have ended in marine slaughter - my most recent mission in the first room I needed to clear (of 4).
All in all, I really like it, just when you think you have a handle on things it all falls apart. Good stuff.
