[quote]explain attack vs impact? weapon elements as well? (i think the public should know)[/quote] There are three damage things to worry about: Attack/Defence, Impact/, and Light Attack is what you want to deal with levels. Essentially it is a "weight class". A level 57 attack gun with half an impact bar would do more damage then a level 20 with a full impact bar. Defense is the reverse of Attack. The higher it is the more resistance to damage you have. Attack and Defense scale to the level of the weapon with some deviation. Impact is what peirces armour for more damage a shot, worry about attack more (for non-scaled multiplayer of course). Impact is a bar, and does not change wih level (it operates likes fire rate and stuff. A Sahara will always have high fire rate and low impact, ect.) Light is how you operate against higher level enemies. I forget how the specifics, but Its important in end game to have lots of light.
