The first time you find yourself in the middle of a well-executed pincer maneuver, with soldiers on all sides closing in, you'll know you've gotten the AI's attention. This intelligent adaptation to your gameplay is a little spooky once you start noticing it. If you pwn the bad guys hard enough in the first few levels, you may even find yourself outclassed when the action gets fast and furious later in the episode. The enemies will start off fairly dumb, but if you find yourself having an easy time of it you'll start to notice the enemies beginning to adopt new tactics. Every bullet you fire, which gun you use, whether it hits or not, all are tracked as you move through the title. If there is a differentiating element to SiN, it is the adaptive AI and stat-tracking that haunts you throughout the game. The few explanatory plot moments are used with the in-game engine, as in cousin Half-Life.

There's a couple of nice action set-pieces, such as a fight against jet-pack wearing baddies from inside a cargo crate being lifted over a body of water. Really, though, what else do you need? Enemy models and map creation are fairly generic, though they are competently executed. Weapons are fairly limited in this first episode For most of the game you have a pistol, a shotgun, and grenades. You make your way through the grubby urban environments, a secret underground lair, and moist crawlspaces, shooting the faceless bad guys that get in your way. Before you can really understand what's going on, another attractive woman comes to your aid, spiriting you away in her auto. You're strapped onto a table, and have apparently been injected with something. You're awakened at the start of this episode staring into the um, eyes of an attractive woman and a well-dressed guy. A 'season' will be a complete story made up of three episodes: a beginning, a middle, and an end. Ritual plans on making these 5-8 hour gameplay releases a regular event.

It would be more accurate to say that this first episode of the 'season' isn't heavy on plot elements. Calling SiN story-light might not be fair.
