Complete Ada Wong's campaign to view a video after the credits.

The sniper rifle is useful for inflicting damage on distant enemies, but incorporating the quick-shot action will double its use as a close-quarter weapon. This will substitute any shotgun, the Desert Eagle, and the Elephant Killer when ammo is scarce for them. Piers' anti-material rifle is a one hit-kill on most enemies near or far.

You can prematurely "cut" a reloading animation by quickly selecting a grenade type item (grenade, remote mine, first aid spray) and then switching back to your firearm. As an alternative, you may also attempt to press [Fire] without aiming to perform a gun-butt with the weapon, which also "completes" the magazine reload, but places your character in the gun-butt animation. This, and other actions (taking cover, diving, etc.), may be faster or slower than weapon switching, but will depend on the situation you are in. This is especially useful in the very fluid situations in Mercenaries mode. This animation exploit allows you to cut down the animation cool-down periods for certain weapons (notably the grenade launcher), allowing you to fire the weapon a few moments earlier. This exploit does not apply to weapons with manually worked actions, such as the six-shot "sniper rifle", the regular shotgun, Piers' Anti-Material Rifle, etc.

Complete all four campaigns to unlock the Unlimited Ammo skill for each weapon.
