Story related, cannot miss.

This trophy is the first one you will get. After you activate the turrets in Jakob's Cover and talk to the claptrap, you will be told to meet Dr. Ned. Once you get to the waypoint and activate the intercom, you'll be tasked with holding off a few waves of enemies while Ned lowers the elevator. You should also take this opportunity to get as many headshots as possible, for the Brains quest. The trophy will unlock once you turn in the quest.

Story related, cannot miss.

You get this mission in Dead Haven, in Dr. Ned's lab. Just pick up the ECHO recordings, proceed to the waypoint, and activate the control panel. You'll have to fight off several enemies in the process, but apart form that, its pretty simple.

Just earn one-million dollars throughout the game. You do not need to have all one-million in your possession at once.

Self-explanatory, play with an employee or someone who has the trophy. Check the trophy boosting guide to boost with someone on here who has it.

Turn on a second controller and go to split-screen. Have the other character slash you and than you slash back. This will trigger the duel. Now just headshot the other character till it dies, and the trophy will pop-up. If you do not have a second controller, play with someone online, but make sure they are the same level or below your level. If they are a high level, you will not be able to kill them fast.

This is the most time consuming trophy in the game, though it can be made easy if you start the quest the first chance you get. This quest is the fifth of a series of a quests, which task you to obtain 10, 25, 50, 100 and 250 brains each. Brains are dropped by zombies if you kill them with a headshot.

To activate this quest, you need to go to Hallow's End (which you will go to for the House of The Ned mission) Once there, open your map and scroll to the south west corner. You will see two little clearings set apart from the main area. The south one is where you need to start the quest. Walk over there, killing enemies in your way (do NOT pick up their brains now!), and you will see a familiar object from the main story. Pick it up, go inside the shack and give it to an old friend from the main story. You can now accept the Brains! quests from him.

One thing to keep in mind while doing this is that brains do not carry over between the quests. For example, if you need to turn in 10 brains, but have collected 15 brains and turn them in, he will take ALL your brains and you'll start at 0 on the next quest, even though you had 5 extra. As such, its best to leave brains on the ground if you've already collected the required number of brains for the current quest. You can always return and pick up the brains- they won't disappear, unless you quit the game.

A good tip is to use the shotgun for headshots. Try not to use elemental weapons, as the last hit might be elemental damage, and not the headshot, and you won't get a brain.
