On this page of the Hitman 3 guide, you will find detailed information on how to unlock the Keep Your Eyes Peeled trophy/achievement. This trophy can be unlocked on the Dubai map and is awarded for causing the mission objective (Carl Ingram or Marcus Stuyvesant) to slip on a banana peel and fall while being evacuated in a parachute suit. After successfully completing this task, you will also finish the Flying Monkey Business challenge.
In the beginning, go through the bar area and head to the art gallery. Walk across the room and enter the staff area through the narrow door on the right.
Climb the ladder to the metal footbridge and turn left. Carl Ingram will be passing in the hallway with security guards. Moreover, there will be quite a few security in the area.
Wait until all potential enemies have passed or are not looking in your direction and immediately jump over the railing - head to the left.
One guard stands at the entrance to the security room. The man is talking on the phone, so he will not pay attention to you. Approach him from behind, overpower him and take his belongings.
Drag the guard's body to the security room and hide in the closet. Then walk up to the sleeping guard's desk and take the banana.
Before you leave this room, open the small safe - the code is 6927. Inside, you'll find an access card for the evacuation alarm switch - take it.
Go through the conference room to the reception area and then enter the penthouse. Inside, you will find two alarm switches that you must activate at the right time. You'll find the first one on the first floor, in the location shown in the picture above.
The second one is on the first floor, in the corridor next to the main entrance - two guards stand by it. Activate the alarm, then exit the penthouse.
Now head to the observation deck and place a banana peel in the location shown in the image above (default Capslock on PC, R1/L1 on PS4/PS5, LB/RB on Xbox One/X/S).
Now move away to a safe distance so that Agent 47 is not detected by the guards and wait for about 2 minutes. After enough time passes, Carl Ingram and Marcus Stuyvesant will appear on the terrace – one of them will slip on the banana peel.
