Unlock weapons and items from the original Army of Two
When you first start the game it will check your system for data from the first Army of Two. You get additional weapons and items to use when you reach the trash container at the start of chapter 1.
Cheat Codes
After beating the game for the first time, the Big Head Mode and Infinite Ammo cheat codes become available in the options menu (cheats may prevent you from earning trophies).
Fully upgrade weapons at the start
Upgrade your weapons/buy new ones at the start of the game, then play until the cutscene with the moral choice and make it. Go back to the main menu during the cutscene with the explosions, select campaign, and select the one you just did. Click new, and you will have all the weapons, upgrades and money from the previous mission, and can upgrade your weapons again. Repeat until all your weapons are upgraded/bought.
