Defeat the robot | Chapter 5 - Alcatraz, USA Secret Files 3 Guide

Last update: 11 May 2016

Once you get to the other building, you face small but dangerous robot called Murphy. In order to get to the door on the other side of the corridor, Nina has to defeat the robot.

(You might save the game here, because after the fight with Murphy Nina will be forced to make a choice, which influences the game end. If you want to try both possible variants, you should save here).

Enter the room behind the door in front of Nina.

You'll find there another combat robot. Take it.

Examine also a scrap heap on the right. Nina will find taser, small flame thrower, buzz saw and drill.

You can arm your robot with one of these tools (one at time). Each of them has its advantages and disadvantages. With taser and flame thrower you can attack on the distance, to avoid enemy mines. This is a big advantage, because explosion of the mine takes 50 HP points of Nina's robot. Unfortunately, these weapons are quite weak - they inflict only 10 points of damage to Murphy.

Buzz saw and drill inflict 20 points of damage but they are close combat weapons and then your robot might get on the mine.

Nina's robot can also set trap with mines but in this case they inflict only 15 points of damage.

Murphy attacks with flame thrower which inflicts 60 points of damage and a cultivator-like arm, which inflicts 30 damage points.

As you can see, Murphy is much stronger but his HP does not regenerate. On the other hand, Nina can replace her robot's weapon and repair it thus sending it to another battle with 100% of HP.

Once you decide which weapon your robot will use, leave the room and attack Murphy. The battle puzzle will appear, where you can set your attack (bottom or top), as well as defense (bottom, top) and in addition to these two options your robot might use one of 3 limpet mines (if you check this). Both robots have 100 HP at the beginning. In order to start the first round (and any next) press the green button at the top right.

I personally think that it is better to equip taser or flame thrower, to reduce the risk of contact with enemy mines. I also feel that it is more worth to choose top defense and attack, but this can be changed after each round - you should notice what kind of attack and defense Murphy has and try something opposite on the next round, but this is not a rule. Of course you must absolutely use mines. One fight has as many rounds as needed to defeat one of opponents.

After eventual lost battle, action moves to the room where Nina has found the robot. You can repair it and change its weapons there. The game continues until you defeat Murphy.

Once it happens, Cassandra appears. During conversation it turns out that mysterious "they" tread on Nina's heels. When Cassandra fights with locked door, Nina has to make a choice: she can try to somehow stop the enemies, thus giving Cassandra more time to open the door or let it go. Regardless of your decision (it has an impact on the fate of characters, presented after the end of the game), Nina is caught.
