Got a boxed copy years ago, and when I saw it in a bundle I wasn't able to resist!
The game hasn't aged really well, and nowadays you could define it "simple" since FPSs have evolved, but the nostalgia factor make it better than what it actually is.
The first use of cell shading I can remember, a nice spy-movie gadget, funny weapons (crossbow!) and a quite enjoyable story.
After a few minutes of tweaking to make it work on modern system I really enjoyed a new run on this game (actually not so long) and...a few deathmatches against bots, I didn't even recall this feature!
Never played? Hard to tell if you would find the time for trying it...
Played years ago? Play it again without any doubt!
