After alot of shouting, nearly breaking a controller and lots of tears of frustration I have finally finished the Marine Campaign on Nightmare.<br />
<br />
If you just use these saves it will unlock:<br />
<br />
Stay Frosty - Marine on Hard<br />
I Love the Corps - Marine on Nightmare<br />
<br />
I admire its purity - Alien on Hard<br />
Magnificent, Isn't It? - Alien on Nightmare<br />
<br />
It Ain't No Man - Predator on Hard<br />
One Ugly Mother - Predator on Nightmare<br />
<br />
Game over man - Beat all 3 campaigns<br />
<br />
All these unlock in order, you wont get the individual mission achievements so play through campaign before using these.<br />
<br />
Just beat one mission on easy and all the above will unlock.<br />
<br />
It will also unlock 10 spear kills, 10 headshot kills and 30 pistol kills if you get one kill with each of the required weapons.<br />
<br />
Dont forget to leave thanks and rep.<br />
<br />
Happy Gaming.
