ACHIEVEMENTS OBTAINABLE: (19)

This achievement counts enemies and allies of different factions killing each other, rather than Duke.

Find a location where multiple factions are engaged in combat, such as standing by a window near a battle between Security Bots and Assault Troopers.

Allow the combatants to kill each other until the total reaches 20.

After waking up in a chair, a robot (Duke Bot) will attempt to execute you.

Perform a Strength Tap (a quick time event requiring repeated button presses) and shoot the robot to disable it.

Automatically pick up the Pistol from the disabled robot.

Kick down the door and proceed through the hallway. An unarmed Assault Trooper is present but poses no threat if you keep your distance.

Enter the prison cell through the door on the left. You can use the toilet for an Ego Boost (increases Duke's health).

Jump through the hole in the wall on the right.

In the next hallway, an EDF Ammo Crate is on your right.

Move through the hallway and around the corner. The door is blocked; shoot the explosive on the other side to clear the path.

After proceeding through the cleared doorway, you will learn the name of your captor, Dr. Proton.

Continue forward. Before the building entrance with the alien fighter, you can find Pistol ammo and a code by going through the door on the right into a small office.

If you did not find the code in the office, look for a security camera monitor in the main entrance to find the access code, which is 1503.

Head to the door at the back of the main entrance.

Enter the code 1503 to unlock the door.

Proceed to the end of the hallway and perform a Strength Tap on the door.

Step onto the elevator platform to proceed to the next level.
