Aggressive Defense System

Aggressive Defense System is a cranial slot augmentation in ''Deus Ex. ''It is a nanotechnological augmentation that, when activated, provides protection against rockets and plasma bolts that come within a certain distance to the player.

This augmentation is installed from the augmentation canister that also includes Spy Drone. Since there is only one cranial slot, Aggressive Defense System and Spy Drone are mutually exclusive options.

Description
Aerosol nanoparticles are released upon the detection of objects fitting the electromagnetic threat profile of missiles and grenades; these nanoparticles will prematurely detonate such objects prior to reaching the agent.


 * TECH ONE: The range at which incoming rockets and grenades are detonated is short.
 * TECH TWO: The range at which detonation occurs is increased slightly.
 * TECH THREE: The range at which detonation occurs is increased moderately.
 * TECH FOUR: Rockets and grenades are detonated almost before they are fired.

Effects
Aggressive Defense System is an active augmentation that consumes 10 units of bioelectric energy per minute.

When activated, the augmentation will intercept and destroy incoming explosive projectiles that come within a certain distance from the player. The interception distance increases based on the tier level, as listed below. Projectiles intercepted by the augmentation include, but are not limited to:


 * Rockets of all types, including:
 * Rockets launched by the GEP gun (blast radius: 192 units)
 * Rockets launched by the mini rocket launcher of MJ12 Commandos (blast radius: 64 units)
 * Rockets launched by the robot-mounted rocket launchers (blast radius: 96 units)
 * Plasma bolts fired by the plasma rifle and PS20 (blast radius: 300 units)
 * Grenades of all types, including:
 * LAM s (blast radius: 384 units)
 * Gas grenades (blast radius: 512 units)
 * EMP grenades (blast radius: 512 units)
 * Fireballs from the flamethrower
 * Darts (all types) from the mini-crossbow

Many other types of projectiles are covered in terms of internal game mechanics, but are not used by enemies; such projectiles include: LAW rockets, scramble grenades, throwing knives, the GEP gun's WP rockets, and the assault rifle's 20mm HE grenade. In general, the augmentation destroys every projectile that isn't a gas cloud, shot tracer, Greasel Spit, or Gray Pisonic Blast.

At tech 4, the interception distance is well above the blast radius of any projectile used by enemies. This augmentation can also be used as an offensive weapon by exploding projectiles fired by enemies onto themselves, especially at tech 4.
