System Shock 2

[graykin]

Someone I know once said that System Shock 2 is a game best enjoyed the second time around, due to its learning curve.

If you're settled in the weapons niche, then I definitely wouldn't put any points into Psionics. If there's a specific aspect of your character that you feel is making you an easy target, then I would definitely focus on correcting that sort of thing ASAP (i.e., if you can only take one or two hits from a melee hybrid then increase your stamina, if your gun has a ridiculous recoil then improve your agility).

Have you been researching the monsters from the organs they occasionally drop? That'll help reveal their weaknesses (some are vulnerable to bullets while being resistant to lasers), and improve your general damage against them.

Lastly, make sure you use the right kind of ammunition against the right type of enemy! Anti-personnel bullets aren't good against everyone!

EDIT: Oh yeah, and if you want to know the stats about anything in your inventory, click the "?" button whilst looking through your inventory, then click the item you want to learn about.

Just throwing these tips out there--I hope they help!
