Parking - Murdering Heather McCarthy | 14: Attack of the Saints Hitman: Absolution Guide
Last update: 11 May 2016
General objectives: Eliminating Heather McCarthy is your last order of business in the Parking stage. Killing the nun can be quite tricky, because she's patrolling an amusement park guarded by a lot of Agency soldiers.
The area where Heather McCarthy can be found was mentioned several times on the previous pages and it's the amusement park (screen above). You will reach this location soon after dealing with the situation with the captured civilian. Heather is moving between two bars located in the far corners of the park. She stops for a while near each bar and then heads to the other one.
The least subtle way of getting rid of the nun is to use remote explosives you may have found near the bus at the parking lot. You would have to throw the explosives towards one of the bars, wait for the assassin nun to get there and then detonate the charge. The explosion would of course alarm the guards and also bystanders could die, effectively lowering your points score.
If you don't want to (or simply can't) use the remote explosives, then you should take some time to familiarize yourself with the area patrolled by Heather. On the higher difficulty levels it's best to proceed towards the left bar.
On the lower difficulty levels on the other hand it's best to use a small wooden bridge as seen on the screen above, heading towards the right bar. Don't cross the bridge right away, because there are some guards nearby and it's recommended to wait for them to end their conversation.
The left bar offers much less opportunities when it comes to eliminating the nun. It's best to attack Heather when she stops close to the bar (screen above) and QUICKLY hide her body in a box afterwards . You can also use the same chest to hide while waiting for her to show up, however taking cover behind the counter should also work.
The right bar grants an alternative way of getting rid of Heather. You can use the rat poison you've located on the ground floor of the motel on a coffee mug found on the bar's counter (screen above). It's important to know that you shouldn't interact with the mug if someone is looking your way, because it'll trigger an alarm. Once you've poisoned the coffee you must hide or leave this area, because the nun's death will be noticed by Agency's soldiers.
It doesn't matter how you've eliminated Heather McCarthy, because the end of this stage will remain the same. Your job is to interact with a door (screen above) located between two of the bars described earlier in the walkthrough. It's worth mentioning that opening this door will take Agent 47 a few seconds, so make sure that no one is heading your way before interacting with it (throwing an object is also a good idea to distract enemy units).
