Boost is a Secondary Badge of the Assault class in Killzone 2 multiplayer.

Description

When activated, the Boost ability will increase the Assault player's standard movement speed by 60% above the maximum. When sprinting, their running speed will be increased to 50% above the standard sprint speed. These increases waive the movement speed penalty if the M80 Rocket Launcher is equipped. Boost will also immediately start regenerating the player's health up to the standard 120% of an Assault's total health, ignoring the 6-second, no-damage delay that generally applies. Once Boost runs out, there is a cool-down period of 1 minute before it can be redeployed. Once Boost is activated, the player's screen will glow blue-green.

The Boost Badge is the only Badge that the player does not have to unlock; it is automatically equipped once the Assault class is unlocked when the player attains the rank of Lieutenant Colonel.

Strategy

• When used with Body Armour, this makes the Assault virtually unstoppable.
• Using the Boost's extra speed allows Assault players to quickly reach their objective points or any team mates who require assistance.
• For maximum effect, time it so that half the Boost time is spent getting Assault players to where they need to be, and keep the other half to engage the enemy.
