Alien Breed

This trophy is level specific, simply run through Alien Breed Level 2 - Mainframe without ever firing a weapon. Before attempting this, back up your save to the PS+ Save File Cloud or external storage. Be sure to have at least three lives, ten keys and enough money to buy extra lives or health if you run into trouble. The map can also be a big help. Ignore all enemies and side rooms and head directly to your first objective. Enemies will run into and damage you along the way. Don't be too concerned with them and continue to the goal. If you see a heath pack in the open, grab it but don't go out of your way for one.

Once you reach the first goal stand in the path of the spinning targets, destroying them in the process. When the countdown begins head towards the exit and get back on the elevator. Once you have the trophy you can load your save from the cloud and resume the game with your lives and keys intact.
