Item description:

Ok folks here you go. Here is a save modded to play the game on Insane without having to beat it once and it will give you max ammo and max trip mines. i also modded the guns so you have the sniper rifle, shotgun, and the super gun from the very beginning. i have also enable big heads and changed the character to one of the girls but im not sure if these cheats transfer with this save so if not the codes are

Bonus weapon
Enter BlowOffSomeSteam as a code at the "Unlockables" menu. The weapon is a gun with a blade attached to the bottom of the barrel that kills in one hit.

All weapons
Enter LockNLoadAll as a code at the "Unlockables" menu.

Custom characters
Enter PeoplePerson as a code at the "Unlockables" menu.

Custom loadout
Enter LockNLoad as a code at the "Unlockables" menu. (This is to change your weapons if you don't want the 3 i setup. if you enable this cheat i believe you lose the max ammo mod.)

Insane difficulty
Enter Revenant as a code at the "Unlockables" menu.

Big head mode
Enter LincolnsTopHat as a code at the "Unlockables" menu.

Resign with 360SR (What Else !)
