Reach Beta - More Subtleties

An extensive breakdown of some of the subtleties in Reach has been posted on bungie.net.  Here's the newest tidbits:

• Field of vision is wider than H3, may consider increasing look sensitivity by 1 to compensate
• Gravity is stronger in Reach, so jumps are less "floaty"
• As posted here, bullets are "instant hit" now, but bullet contrails may look funny and not represent actual shot
• Crouching slightly improves accuracy
• Crouching reduces fall damage
• Melee will take down shields completely, but will NOT break through shields.  This is a pretty big difference and may be manifesting in many frustrating ways.  But if you charge in with AR and punch, the other guy will not die if he had *ANY* shields left (even 1%) before the melee.  You can compensate in the Reach Beta by punching twice quickly (though the double punch is considered a Beta bug and may go away in production.)
• [Update] Needle rifle is not "instant-hit" like the DMR.  3 needles to an unshielded body will combine kill, as will 1 head-shot.
• Needle rifle has automatic fire capability by holding down the trigger.  Recommended to use it in 3-shot bursts or single-shot mode for accuracy though.
