Full of glitches and other problems
It's as if you didn't even play through it yourself.
Froze on the informant running over buildings for no apparent reason, after nothing seemed to be hitting him (or the other 2 people on screen) using shuriken.
If you return to the safe house after being killed by the first yakuza, you complete the mission anyway.
If you retry on the bike chase, you start with no ammo.
There's no way to restart or leave in any mission without failing, so for example if you're stuck on the camera finding thing or run out of ammo there's nothing you can do about it other than restart the whole game.
Objectives are pretty unclear, so you end up wandering around aimlessly. Got bored incredibly quickly. The idea of finding and shooting informants out of random buildings is pretty idiotic too.
The doorways in buildings often don't have any relation to where you came in from, so you end up going backwards unintentionally (not really a problem, just annoying).
Finally, most of the weapons are ridiculously inaccurate.
This was a real disappointment, especially considering act 1 was better.
