I am at the part where the soldiers make an appearance... I am not impressed at all.
The soldiers sound terrible (the voice overs) and the MP5 type weapon is horribly inaccurate and not nearly as deadly as the soldiers themselves (I am playing on Hard). Furthermore they like to be able to attack you from so far away with pinpoint accuracy that it is impossible to return fire. The same with the turrets, why bother giving the turrets a laser sight and rotation feature when they can identify your presence even when they aren't looking at you... that is stupid.
The inconsistent application of the "iron sights" view is pitiful.
I mean it looks great, but it plays terribly. They need more balance in the game....
The AI prefers to run from hiding place to hiding place and take pot shots at you from various angles instead of engaging you. This may be "smart" way to vanquish your enemies, but it is not fun.
