I reckon it's worth it, it's not exactly a shoot-em up in the purest sense as you have to be careful with ammos (military grade and home made, latter is inferior and cause jamming), and prepared to feel frustrated not hitting your target.
No HUD, you go by feel, if the screen start to go red/heartbeat quicken, you're gunna die if you keep this up.
The story alone is worth playing, the book also worth reading too.
2033 is free with gold, worth a play?
