Man, Raw Data is a trip. I still feel like all the other characters have major design issues, either by themselves (Boss) or clashing against the design of the rest of the game being based on frenetic massive waves of enemies (Saija and Elder).
But Bishop, the dual guns Gun Fu man, holy shit. If you want a game that'll bring out your inner Gunslinger Dante and can't wait for Doom VFR, get Raw Data. You can even charge your guns! And the tracking remains solid throughout so you can just focus on going crazy on that stylish trigger action.
As MattAces said earlier in the thread, use the Walking mode and remember you can double-tap the Move button to teleport even in this mode. Being able to strafe and dodge while shooting shit makes the game much more comfortable to play.
As for my own recommendations, I recommend playing seated for comfort, but make sure you use a chair without arm rests as you'll need to reach for your gun holsters on the regular. Place the camera higher than your own head (in my experience, 2 to 3 heads higher than you is the best) and at a distance of between 1.5 and 2 meters as per Sony's own recommendations. Make sure your Moves stay within the picture frame with your arms extended up, down and to the sides and you're golden. I have pretty much zero issues like this even when shooting flying enemies at any angle.
