Hi I fixed all the problems so it will now work for everybody both in campaign and spec ops.
I made it.
List of features.
Super jump - Jump really high.
Unlimited steady - Unlimited steady while using a sniper.
Super knife - Knife from any distance.
Dual Wield - When you pick up a new gun, you will have two. This doesn't work for all guns.
No bob - when you sprint the camera view will not jump up and down.
Explosive - explosive bullets.
Wallhack - if u stand close to a wall you can look through it.
No Kick - Your view will not move when you get shot.
Burst to Auto - Burst weapons become automatic.
Give All - Gives you all the weapons in the level, but no ammo so it is useless.
Aim Assist - Aka Fake assist. Some people say it bends the bullets, but its a lie.
Spot Assist - Makes it easier to spot enemies.
How to use the crosshair:
1. Toggle on and chose your color.
2. While in game, let go of your mouse, click the windows key and now click the K key.
Step 2 centers the crosshair and it can only be done while the crosshair window is open.
I only listed the ones that might be confusing since you can see the rest in the picture.
I have also attached the cheat engine table i made for MW2 SP.
The table contains a couple of hacks which isn't in the trainer for example: 10x Regenerate.
