Easy "Alien Bastards are Gonna Pay" trophy

Select the third or fourth difficulty setting. From the start of the level, fall down the ventilation shaft and run directly to the alley behind the movie theater. Use the pig cops as platforms to jump onto the small lip running along the wall. From there, go to the bridge. Once on the bridge, run past the pig cop and end the level.

Easy "Hail to the King, Baby" trophy

Note: This requires the help of a friend. Play the "Stadium" level (Episode 3, Mission 11). Have your friend host the game. He or she will spawn in the elevator, and you will spawn on the field and can quickly collect the RPG. Enable the Aim Assist option so none of your shots miss. Get to the corner of the stadium, next to the RPG ammos. You should be able to target your friend's respawn point from this position, and can collect the nearby ammunition when needed. Have your friend repeatedly press [Use] to respawn immediately as you kill him or her repeatedly with one shot of the RPG.

Easy "Oomph, Uugh, Where is it?" trophy

This trophy can be earned through normal progression, but you can grind by repeating the same level multiple times. The achievement counts secrets found across all play throughs rather than the number of unique secrets discovered.

Easy "Shake It Baby" trophy

The first time that this can be done is during episode 1 level2, "Red Light District". Enter the strip club, walk up to a stripper and press [Interact].

Easy "Take No Prisoners" trophy

Select the Piece Of Cake difficulty setting and episode 1 level 1, "Hollywood Holocaust". Explore the level carefully, killing every enemy encountered. Also remember the secret areas through the ventilation shaft in the bathroom and behind the movie screen. There are at least four spawnable sets of enemies that may count toward the kill count towards the end of the level:

Jump into the flaming dumpster.
Walk through the seat rows in the theater.
Enter the room behind the concessions counter, and walk to the security monitor to open the secret behind the counter.
Jump on top of the projector in the projection booth to open the secret wall in the same room.
