You will need to do 3 playthroughs: A playthrough consists of all the levels of Act I and Act II (first and second row). Use the Complete Mission cheat to go through all levels in singleplayer, multiplayer, and in zombies mode. Make sure to use the Collect All Loot cheat on every level on either your singleplayer or multiplayer playthrough to avoid having to replay levels. Cheats work in both local and online coop.
Single/Multiplayer just means you are one player or 2+ players, you can do all trophies in local or online play (press P to toggle in lobby), you will need 2 controllers for local coop.
For Zombies mode, you need to change the version on the main menu from Enhanced to Zonaco.
Cheat Codes:
You will only need to use Collect All Loot and Complete Mission for getting the trophies, but God Mode (etc.) will be useful for some of the miscellaneous achievements.
F9, Up, F9 - God Mode
F9, Right, F9 - Unlimited Ammo
F9, Down, F9 - Invisible
F9, Up, Up, Up, F9 - Complete Mission
F9, Left, F9 - Display Entire Map
F9, Right, Right, Right, F9 - Collect All Loot
You can check trophy progress for each level in the level select.
The first one is for single player completion.
The second is for multiplayer completion.
The third is for completing the mission with no deaths.
The fourth is for getting all loot in the mission.
The fifth is for zombies mode completion.
Whacked can be gotten in any PvP map, but can also simply be unlocked in the Act I Epilogue. Must be done online.
For Slippery, you need to do the first level in the game in under 1:10 while collecting all loot. Each coin you miss increases your score by 10 seconds, and using cheats defaults your time to 1 hour, so this must be done legitimately. Go Locksmith and run through all the lasers. Near the end clean out the place from top to bottom since bottom has a side exit. This may take a few tries to learn the route but is very doable.
All other miscellaneous can be easily cheesed with this Workshop map. Workshop can be buggy with unlocks, you may need to try multiple times. You will need either 3 players or 3 controllers for Play It Again Sam.
