Dead Space Extraction Cheats

After you beat the game go to any level and you'll see a box/square with every weapon you've collected from first to last level choose any weapon you want and it'll be you're secondary weapon.

The guns are "unlocked" as you find them scattered through out the game. Level 1, 2, and 3 have 1, 2, and 3 weapons to pick up respectively. Other levels have about 4 or 5. After you find a gun and finish the chapter, you can then choose it as your starting primary weapon in the challenge levels.

Ripper
Primary: Hold the trigger down to hold a spinning saw blade out in front of you. Move it around to cut limbs off and block enemies from grabbing you. Though each blade lasts long enough to cut through multiple enemies,but it is very short range only letting the longer range physical attacks get you. It does however push them back or cut limbs off, though only to one necromorph at a time.
Secondary: It shoots one of the blades straight out with a good rate of fire. It is similar to the horizontal plasma cutter, but a good hit will take down an enemy instead of just a limb and it will go through multiple targets. Make this your primary use and stasis enemies to get that good head/neck shot.

Line Gun
Primary: It shoots a very wide beam that travels through enemies and deals massive damage, but they travel noticeably slow enough that moving enemies that are far away are difficult to hit. A decent upper body shot will sever the head and arms of most targets.
Secondary: Fires a mine that has a huge explosion, though it has a delayed timer. Those just outside of the kill radius will be knocked down.

P-Sec Pistol
Primary: High rate of single shot fire, though pretty low damage.
Secondary: Knocks back enemies more so then primary, trading off lower rate of fire, extra ammo usage, and less damage. Stick with firing primary real fast.

Pulse Rifle
Primary: Very high rate of fire and holds enemies from advancing. To conserve ammo try shooting in quick bursts.
Secondary: More like a shotgun blast with a wide dispersal. It takes more time then I'd like to charge. Haven't found a use for it yet.

Flame Thrower
Primary: Great at crown control, primary actually has a short to medium range. It sets them ablaze and halts them in their tracks even knocking them back some. I find that repeatedly firing works better then holding down the trigger to spray them knocks them back a little more and conserves ammo since your not firing at the nothing between the targets. Then quickly switch to the rivet gun to add a shot or two.
Secondary: Missing your target may still cause some damage from a small explosion, but not much considering it uses up extra... 

You cannot see how many weapon upgrades are left/you missed in a chapter except by completing the chapter again.

Write it down so you know what levels to replay to upgrade your weapons further.

I haven't found all of them, (and I'm replaying every chapter to see which ones I missed) but I think if you do find all of them, you will have fully upgraded all your weapons by the end of the game.

When you reload, the crosshair has a progress bar that encircles it starting at the bottom and going clockwise. Did you notice that there is a gray rectangle that looks a lot like a stasis ammo slot on the left or upper left side, but it is the only rectangle

If you are using the zapper/pistol/whatever:
Shake the Nunchuck to begin reload
Pull the trigger (attempt to fire) when the progress bar is in the gray rectangle

If you use other control setups:
Press your reload button to begin reloading
Press the reload button again when the progress bar is in the gray rectangle

Each weapon seems to have a slightly different size rectangle in a slightly different position, so get to know the weapon you're using.
