Perfect Dark: Isno Style

Peek and Snipe
This tactic is very useful in single player and can really save your life in Perfect Agent. It involves three steps:

1. Peek out from behind a wall using the C-Left or C-Right buttons.
2. Let go of these buttons and go back behind the wall. You should now hear the enemies bullets start flying by.
3. Go out and rush the guards with guns blazing while they sit and wait, painfully reloading their guns.

The Lure
When you have guards piling up or you enter a situation where enemies surround you, run away to a better place. This way, you can lure the guards into a trap or a more favourable situation for you.

Objects
This trick requires the use of, well, objects! Things like tables, crates, and other things can become your best friends in the solo missions because they will shield you from bullets. If you want this tactic to become even more useful, be sure to take advantage of the Peek and Snipe method. Just make sure the object doesn't explode!

Penetrating Weapons
Nothing feels better than killing an enemy before he even sees you. Using penetrating weapons, you can pump bullets through doors or in the case of explosives, even walls. Wondering what the penetrating weapons are? Check out the list below:

1. DY357 Magnum
2. DY357-LX
3. Callisto NTG (High Impact Shells)
4. Farsight XR-20
5. Any explosive weapon

Crouching
Want to increase the aim of your weapon and have a lesser chance of being hit? Crouching is what you want. Double crouching will give you even better aim and allows you access to small passageways and vents.

Fist Fight!
When you have a large group of enemies all packed together, sometimes the best course of action, if you don't have explosives, is to charge at them with fists flying. As long as you have switched to Disarm, you will probably recieve little or no damage while grabbing their weapons. Once they are all unarmed, pull out a gun and take out the resistant guards. The others can just be knocked out (to save ammo).

Motion Blur
From time to time, you'll run into an enemy who carries a Tranquilizer or N-Bomb, and will give you motion blur. It is caused to disorient and confuse the player. Obviously you don't want this, and want to get rid of it as soon as possible. Unfortunately, you can't wait it out so you must run around to wear it off. If you haven't experienced much motion blur and want to see how much a weapon will give you, look at this list:

Low Amount: Repeated punching, pistol whipping, or nerve gas.
Medium Amount: Tranquilizers, Poison Knife, Crossbow, or Radioactive areas
Very High Amount: N-Bombs

Speed
If you need some speed to run away, chase someone, or otherwise, strafing is the best thing you can do. Continuous strafing gradually builds up your speed until it peaks at a certain point, and you go three times faster than a non-strafer.

Shields
Shields can sometimes make the difference between living and dying because theygive you an extra bar of health, essentially giving you two lives. One thing to remember: When you see a shield, grab it!

Proxy Mines
Proximity Mines in the solo missions will always come in handy. The only reason they are there is to help you out, like the shields, so always use them when you get them.

Burst Fire
Going trigger happy in the missions isn't the smartest thing to do. As an alternative, try using short controlled bursts. That way, you'll make less noise and conserve ammo, which is a necessity in Perfect Agent.

Reload... Now!
One of the worst possible scenarios you can get is when you confront a horde of guards and find that you only have one bullet in your clip! To prevent this from happening again, you'll want to manually reload your weapon before you move on. That way, you'll atleast have a fighting chance if you go up against a horde of enemies.

Damage
Location, location, location! Where the bullets hit really does count, especially in Perfect Agent. Refer to this list to see where to aim your bullets for damage.

Head: 100% Damage
Body: 30-50% Damage
Limb: 15-25% Damage
Other: (Gun hit) N/A
