what is your game style
how do you use your suit
what are your strategies

Hey there connorp30. I have a youtube channel I recently made specifically for crysis 2 and I thought you should check out my videos and see first hand what I do. I am trying to record videos with all different setups so I can open up the game of crysis 2 to different play styles and show that that isn't just one good setup or weapon and show the style of play you can use with each specific one.

Basic strategy: Number one most important thing I can tell you is to manage your energy. Never run in the open or into a fight with less than 50% energy unless you know you can get the kill and have Energy Transfer on.

2) Stay cloaked as much as possible and use Nano Vision as much as you can. Running these two things can be difficult when keeping up with your energy but this will give you the edge when you run up on an enemy cloaked or not because A) You are cloaked so they have to look hard to see you B) You see them with much more ease and can get the jump on them.

3) Cases may vary but most the time you want to switch to armor mode before firing. Do not break stealth by firing at someone and end up not having any energy. I come in many cases where I can turn around or be face to face and kill someone who does so. I have had less success killing someone who has the drop on me when they switch to armor mode.

4) Keep on the move after a kill. Enemy teammates or surrounding players will take notice and come looking for you. This will also mean you need to cloak up when the area is clear and move to a position to recuperate.

If you have not been able to do well, the easiest and most basic set up will be:

Primary weapon: Scar - Red dot & Extended mag

Secondary weapon: AY69 if you feel the need for a machine gun or use the M12 Nova if you have a nice trigger finger. AY69 lacks in a lot of damage so you may not be always successful when killing someone if you need to switch. It requires basically a full clip to kill someone until you get the extended mag.

Module: Energy Transfer
Stealth Enhance
Mobility Enhance

This set up will help you manage your energy with ease while being able to play fast pace and move around quickly with fewer to no stops. If you can find someone to kill quicker than your energy drains with this, you won't make any stops to regain energy. Only stop should be a death.

Right now for me I use the stealth ----> armor strategy with:
SCARAB (no attachments yet)
nova
frag grenade
mobility enhance- allows you to sprint in either mode for longer and still be able to retain energy
stealth enhance- faster transitions and you are harder to see
armor enhance- most versatile when fully leveled, lower drain + faster movement speed

another nice module is an upgraded nano recharge for the energy charge and health recharge delay, less down time out of stealth.
