With its great optimization and well paced gameplay, Dark Sector's in no way a bad game. It's just nothing out of the ordinary, since it doesn't break away from the cliched corridor shooter and in the bargain, fails to establish a distinct identity for itself. As it stands, the game's worth a shot if you're an action game fan. Play it in short bursts, and you won't get too bored of it. While the game's not available in retail, you can buy it off Steam for US $19.99 (about Rs.1000).
