Syphon Filter: Dark Mirror Help?

Hey, i'm wondering is there's any tips on how to shoot and aim well at the same time? Lol, i can't really do it much without target locking (This is for online).

I'm only asking because those T3's keep destroying me.

use the free aiming set-up I like the advance aiming (nub for aiming, face buttons for moving) find a weapon you like, take some time to get use to the maps and do your best. soon you'll rank up and be a better match for them.

Haha well, i'm a R2 (soon to be R3), and i do fairly well against T3s (unless they use cheap weapons like MGL, and such), but i just want a better control when i face them, and i want to be on the same level :P Thanks for your advice!

I only have 3 badges, and 4 guns :P
