Power Jump gives the player 2.2x times the height of a normal jump.
It takes 20 energy to use.
 
The Air Stomp is a velocity-based attack. The higher you are, the more time you have to fall and the faster you'll go, naturally.
Depending on the height, the Air Stomp can deliver from a minimum of 40 damage to a maximum of 220 damage.
Similarly, the radius of the Stomp can grow from 2 meters out to 7 meters.
A simple Power Jump doesn't come close to getting enough air for more than the minimum damage. You need some elevation, a few seconds of air.
 
Speed (sprinting) will boost the player's forward speed to 1.8x.
Speed drains up to seven points of energy per second.
 
Stealth drains the player's Energy by five points when standing still.
Based on how fast the player is moving with stealth, the suit will drain up to fifteen points per second.
 
Armor drains 2 to 7 points of energy per second depending on the player's movement speed. His movement speed is also decreased to 80%.
Armor absorbs a percentage of damage to the Player's health. 35% of the damage is diverted to his Suit Energy.
If for example, a player with Armor is hit in the torso for 30 damage. His health takes 19 damage.

    Some stuff. Info on all of the Suit Modules below the (currently empty) weapon chart.
 
    The Player has 100 Health.
 
    The Nanosuit has 100 Energy.
    After one second of not using any energy draining functions, the suit will recharge 30 energy per second.
   If the suit is reduced to 0 Energy, it stays disabled for three seconds before recharging.
 
    Recoil for most weapons is low (it should be, you have a big muscle suit) and character models are rather stiff and upright.
    There is not a lot of randomness when the weapon is sighted (much less with Aim Enhance), meaning accuracy and reflex are pivotal in a shootout. Aim for the head.
 
   Weapons start off with a certain amount of Damage out to a set Distance.
    After that range, the weapons in Crysis 2 lose Damage Per Meter to a Minimum Damage.
    For example, the SCAR loses 0.25 damage per meter until it reaches 25 Damage.
    The Single Fire mode on assault rifles has its own Damage and Range and Rate of fire.
    Silencers do not alter damage, but they typically halve the maximum damage Distance.
 
    Weapons in Crysis 2 have their rates of fire measured in Rounds Per Minute.
    Divide 60 by that RPM and you'll get the FireTime, or time between each shot fired.
    The Rapid Fire Suit Module multiplies the rounds per minute uniquely for each weapon.
 
    Weapons have a single Reload Time. Exception being the Marshall.
    Along with the Reload time is the Fill Ammo Reload Fraction or "AddTime", the point when the ammo counter changes.
 
    The Spread of a weapon has both a maximum and minimum, both reduced by a 0.8 multiplier when crouching.
    The Point Fire Enhance Suit Module multiplies the spread of each weapon.
    The Laser Sight Attachment reduces the spread of most weapons to around 3.0 and less when firing from the hip.
