IronStorm./World War Zero
Not really that it is that bad. It is a pretty bog standard FPS. It just had a pretty good concept of a story and setting, WW1 still being fought in the 1960s, so you think lots of great dirty brutal trench fighting.
But as I say, it is a bit ropey, the weapons are all a bit crap, for instance the pump action shotgun will only hit someone if you are right next to them. The automatic rifle is just simply not that good. Poison gas grenades are a nice, previously underused touch, but they are again a bit shit.
Basically it is a nice and original idea, made a bit crap by a over complicated storyline about a stock market gambling ring based on the soliders kills. How this would work, it does not seem to be clear.
Hopefully there may be a sequal which is better and more coherant.
