Leave it up to avid fans to deliver not one, but three days worth of reports and notes from the New Vegas display at PAX. Intact Garden Gnome brings us word from day 1, day 2 and day 3.<blockquote>I also caught a near complete screen shot of the tutorial of the different ammo types:
Armor Piercing: Ignores a large portion of the enemy's Damage Threshold, does slightly more damage.
Hollow Point: Does much more damage but is easily blocked by armor.
Over Charge: Used by Energy Weapons, increases damage but degrades the weapon more quickly.
Slug: Used by shotguns, slugs replace buckshot with a single, powerful bullet that is more accurate.</blockquote>See lots of camera phone shots here.
