I remember the original games that this game is supposed to pull its inspiration from, and they were about 23 times cooler than this game - and that's saying a lot.
The game looks average, but looks aren't what is bringing this game down. Its the completely contrived gameplay - a shooting gallery? Who still makes that. The AI is horrendous as they do not seem to notice people getting shot right next to them. After killing everyone on the river bank, stroll to the little wooden hut on the left - there is a guy leisurly smoking a cigar

Hehe I played it twice and saw that guy every time.
The stealth aspect with the spy is laughable. First of all, there are invisible walls EVERYWHERE, so you cannot circumvent enemies. It took me bloody 20 minutes to figure out that in order to progress past the first patrol in the stealth mission, I just have to dash straight past them!!! What the hell - what kind of spying is that. All the stuff about don't be noticed, sneak through is completely useless - I tried sneaking but when I got discovered I just shot the guy... A patrol of guys just 20 meters down the road didn't seem to care at all, so when I got to them, they were smoking a cigarette. So I killed them as well, got the officer's uniform and strolled past the guards 20 meters away that curiously did not see or hear anything from my machine gun.
Looking through the lock? Why - just bust down the door and kill the two pathetic enemies.
Sad - this sounded like a good idea, but crappy AI and invisible walls coupled with terrible level design - spies running past patrols like in Looney Tunes - just makes this game lousy.
I don't understand why this demo was released.
