I've compiled a little guide for finding all 30 of the intel locations in the game so you can unlock all the goodies
Here's what they unlock :-
2 Pieces -
"CoD Noir" : Play the game in black and white,
4 Pieces -
"Photo-Negative" : Game colours become inverted,
6 Pieces -
"Super Contrast" Game's contrast increases,
8 Pieces -
"Ragtime Warfare" : The game feels like an old silent movie,
10 Pieces -
"Cluster Bombs" One frag grenade thrown equals five in explosion,
15 Pieces -
"A Bad Year" : Enemies explode into tyres when shot,
20 Pieces -
"Slow-Mo Ability" : Game plays at 40% normal speed,
30 Pieces -
"Infinite Ammo" : Exactly what it says on the tin.
I didn't write the guide, just edited others I found into a Word file which is easy to print out & follow
